Broadcom Linux bnx2 and 10GigE Virtual Bus Drivers(VBD)

Version 2.0.24b
09/19/2011

NOTEs:
1. These driver files are the original files from the vendor. They include multiple driver
change histories for multiple Linux Operating Systems. Some drivers may or may not
pertain to all Linux Operating Systems but are part of this file for references.

2. This package may or may not contain iSCSI driver support even though there may be mention
of iSCSI support in the documentation.

Highlighted Fixes:
==================
- BSOD with BASP when IPV6 runt packet is found in buffer
- Provide the ability of BASP to fix the BASP MAC address
- 1g/10g Mezzanine cards lose TOE capability when BOFM MAC address is applied to card
- Addressed 10g Linux driver compilation errors on some older vanilla kernels
- Linux iSCSI - TCP connection erroneously closed
- 10g Linux driver - MSI-X configuration was not properly cleared when MSI-X was disabled.
- 10g Windows driver - Fixed race condition that could occur during driver update.
- 10g Windows driver - Fixed problem where a system reboot could occur if one port of a dual port device was being enabled/disabled while heavy traffic is running on the other.
- 10g Windows driver - Fixed inability to wake system via magic packet when Locally Administered MAC address was assigned.

Feature Additions:
==================
- Non-switch dependent NIC Partitioning support added to all components for 57712 based mezzanine cards.
- BOFM support added for NIC Partitioned devices
- Added support for Red Hat 5.6, SLES 10 SP4, and SLES 11 SP1

********* Currently known issues and limitations with Broadcom NetXtreme drivers and devices. **********

1. BASP (the Broadcom Advanced Server Program) will appear to be bound to all adapters in the
system once loaded. This binding is normal and is used only to determine compatibility with BASP.
The binding is not active, as indicated by the gray background of the selection box. This pre-binding
will not interfere with bindings to other software protocols.

2. The NetXtreme II drivers have two parts, the VBD driver and the NDIS Client driver. This combination
of drivers can be used for WinPE installations as long as the WinPE image is built with the /PnP option.
WinPE images that are booted with the -miniNT option will only load the NDIS driver so NetXtreme II
network devices will not be functional in this environment. Use the -winpe option instead of
the -minint option to boot WinPE when using NetXtreme II devices or use the special RIS driver contained
in the distribution package in the NX2_RIS_Driver directory of the unpacked files.

3. Specifying network settings for NetXtreme II devices using the Microsoft unattended answer file does not
work using the PCI Bus/Device/Function designation to specify adapters. This is due to the NDIS
personality of the NetXtreme II device being a virtual device which means it does not have a
physical Bus/Device/Function address. MAC address designation does work and may be used in conjunction
with Bus/Device/Function for a complete solution. A program called netset.exe from Microsoft, available
in the Windows 2000 Server Resource Kit, can also be used to apply network settings after the unattended
install. Netset.exe uses the answer file to apply the network settings specified to the adapters in
the system. See Microsoft Knowledge Base article 268781 for more information on netset.exe.

4. The first time diagnostics are run in a Windows environment on NetXtreme II devices, the diagnostic
driver must be installed. Windows will either automatically install the driver, in which case, no action
is required by the user, or Windows will ask to be directed to the INF file for the diagnostic driver. If
you are prompted to install the driver, please direct the Windows dialog to search for the driver in the
directory where the Broadcom driver package was unzipped. You may also search your hard drive for the
file “bxdiag.inf.”

5. When loading drivers through the PNP (Plug and Play) method, users can occasionally end up loading the
RIS drivers accidentally. Generally this occurs when a user is asked to point to the proper driver
for the device, and the user selects the folder containing the RIS drivers as the driver for the device.
This can result in network connections that fail to communicate across the network, as the NDIS driver
will fail to bind to the devices. The most obvious way to identify the problem scenario is to open BACS
and look at the network adapters displayed. Adapters that have the RIS drivers installed will be grayed
out. Observing the driver loaded for the System Device portion of the Broadcom NetXtreme II devices will
show that the RIS driver is loaded. Additionally, attempts to load the drivers using the installer will
result in NDIS drivers displaying a yellow bang, as they’re not able to bind to the VBD driver. The easiest
way to correct the problem is to run add/remove programs on all installed Broadcom devices, and then re-run
the installer.

6. Windows Pre-installation Environment (WinPE for short) does not contain native support for 5708, 5709,
5716, 57710 and 57711 devices on operating systems prior to Windows Server 2008 R2. In order to “inject”
driver support into Windows PE, refer to the steps provided by Microsoft at:
http://support.microsoft.com/kb/923834/en-us.
Broadcom 5708 Network Controller support is available as a native driver package in the Windows Server 2008 OS.

7. Network Teaming limitation with iSCSI offload: When iSCSI offload is enabled on Broadcom NetXtreme II
NIC's or LOM's, only SLB teaming mode is supported. In order to create other teaming modes like 802.3ad
and FEC/GEC, you will need to disable iSCSI offload. You can disable the iSCSI offload by
a. launching the Broadcom Advanced Control Suite 3 (BACS 3).
b. select the adapter you want to add to the team
c. click the configurations tab, extend resource reservations.
d. Uncheck iSCSI resource.

8. When iSCSI devices are installed on Windows Server 2003 or Server 2008, they will have the same friendly
name. View devices "by connections" in BACS3 on for managing iSCSI devices.

9. Restoring the team configuration with static IPv6 addresses may fail. Use either DHCP addresses for team configuration, or restore the team and re-apply the IP address manually if this issue is encountered.

10. When working in BACS while being logged into W2K3 x86 with a non-administrator account, the same icon
that is used for a non-teamed adapter is being displayed for a teamed adapter. This is due to the fact the
non-admin account cannot query the driver due to insufficient privileges.

11. Windows Server 2008 R2 is expected to support the ability to utilize the TCP Offload Engine (TOE) on
child partitions for supported Guest operating systems. However, the stack supporting this feature was not
fully matured upon the completion of this Windows drivers release. As a result, we do not recommend
enabling this capability with these drivers until an update to resolve these issues are released. This
is now understood to be a third-party issue.

12. After upgrading to this version of the software in W2K8 we have noticed that during a team restore in
BACS3 that not all of the IPv4 addresses for VLANS are restored properly. This may require that the team
be recreated and saved.

13. Remote install of Windows Server 2008 R2 over non-offload path (MSFT stack) with new Broadcom adapters,
e.g. 57711, which are not supported by the inbox driver will fail. The problem is due to a conflict between
the inbox (boot.wim) driver not able to support the new adapters. Although the installer provides a newer
driver externally during the installation, the OS reverts back to the inbox. Please refer to the workaround provided through the following link:
http://attachments.wetpaintserv.us/JA9hJcVpHrEi11mJ19vYVg%3D%3D23856.

Alternatively, Microsoft’s proposed solution is to build a custom install DVD by extracting the boot.wim
and overwrite the .INF and .SYS files with Broadcom’s newer driver set. Please read Microsoft’s WAIK
documentation for instruction process.

Note: Remote install of Windows Server 2008 R2 over Broadcom iSCSI Offload path does not have an issue.

14. Flow control statistics (MAC Sent X-ON, MAC Sent X-OFF and MAC Rx w/ no Pause Command) are reported
incorrectly within BACS for 57710 based adapters. There is no functional impact and device is working as
expected.

15. Receive Side Scaling (RSS) on TCP offloaded connections require a minimum of 8 gigabytes of RAM and
only works for the 64-bit version of Windows Server 2008 and Windows Server 2008 R2. This feature is not
supported in Windows Server 2003 due to a limitation in this operating system. RSS on non-offloaded
connections, however, is supported for Windows 2003 SP2 and later.

16. WoL with NPar: When using Wake on LAN (WoL) with NIC Partitioning, all of the devices that comprise
a port must be shut down to cause the WoL configuration to be written to the controller during operating
system shutdown. If only a single function is shut down, the WoL configuration might not be written to the controller, and the controller might not wake.

17. Editing BASP teams: There is a known problem where editing a BASP team in BACS can sometimes cause a
failover to occur on another team. This is currently believed to be a Microsoft issue, and Broadcom is
pursuing a fix or workaround.

18. NC-SI with IOMMU: There is a known problem using NC-SI with IOMMU enabled, that can cause link down/up
under stress conditions. If this occurs, disabled IOMMU in the BIOS.

========================================================
Fixes
-----
1. Problem: (CQ53174, CQ53400) iSCSI detected conn error and ping timeout.

Cause: Race condition between cnic driver and hardware DMA'ing a
new status block with new iSCSI events. The bug was
introduced when adding FCoE support.

Change: 1. Add proper memory barrier after reading status block.
2. After servicing FCoE EQ, we must loop back and check the
iSCSI EQ again because we may have a newer status block
index that is read after servicing the iSCSI EQ.

Impact: bnx2x iSCSI.

bnx2 v2.0.23b (Feb 01, 2011) cnic v2.2.13b (Feb 01, 2011)
=========================================================
Fixes
-----
1. Problem: EEH errors on PPC when loading bnx2i

Cause: KWQ page tables set up in wrong endian order, causing EEH
errors when sending the first KWQ message.

Change: Fixes page tables endian order.

Impact: PPC only.

bnx2 v2.0.22f (Jan 18, 2011) cnic v2.2.12f (Jan 18, 2011)
=========================================================
Enhancements
------------
1. Prevent AER error messages on PPC. PPC does not support AER.

Impact: 5709 only.

2. Integrated with bnx2x 1.62.10.

Impact: bnx2x iSCSI only.

bnx2 v2.0.22e (Jan 12, 2011)
=========================================================
Fixes
-----
1. Problem: change MTU would fail for the CNIC IRQ.

Cause: Mismatched module IDs for request/free IRQ.

Change: Masquerade as CNIC when cnic ops are called from bnx2.

Impact: ESX only.

bnx2 v2.0.22d (Jan 11, 2011) cnic v2.0.12d (Jan 11, 2011)
=========================================================
Fixes
-----
1. Problem: NetQueue would not properly allocate RX queue

Cause: BNX2_NETQ_HW_OPENED bit was not properly set.

Change: When the NetQueue device is openned properly set the
BNX2_NETQ_HW_OPENED bit in the netq_flags field.

Impact: ESX NetQueue

2. Problem: NetQueue could possibly get out of sync with the uppper
layers

Cause: The queue cleanup code between the driver and upper layer
is not synchronized

Change: Introduce the NetQueue lock to synchronize the cleaning
of the queues between the vmkernel and the bnx2 driver.

Impact: ESX NetQueue

3. Problem: iSCSI may not work if multi-function is disabled in NPAR NICs.

Cause: Bug in logic in detecting NPAR mode.

Change: Offload bit should not be checked if iSCSI MAC address is invalid.

Impact: iSCSI on 57712 NPAR NIC.

bnx2 v2.0.22c (Jan 6, 2011) cnic 2.2.12c (Jan 6, 2011)
=========================================================
Enhancements
------------
1. Change: Updated to 6.2.1a firmware for 5709. It has fixes for
CQ51953 (ESX netqueue issue) and CQ51894 (iSCSI performance).

Impact: 5709 iSCSI and L2.

bnx2 v2.0.22b (Jan 4, 2011) cnic 2.2.12b (Jan 4, 2011)
=========================================================
Enhancements
------------
1. Change: Send netlink IF_DOWN message during cnic_unregister_device().
This fixes the problem of bnx2i referencing freed hba when we
used to send the netlink message during cnic_unregister_driver().

Impact: iSCSI.

2. Change: Upstream fix for memory leak in cnic_alloc_uio_rings() when
we cannot allocate all the memory.

Impact: None.

3. Change: Upstream fix to remove flush_scheduled_work() since it is
obsolete.

Impact: None.

4. Change: Do not allow iSCSI on bnx2x devices in MF mode. The
hardware does not yet support it.

Impact: iSCSI.

5. Change: Removed VLAN_ID from the parameters of
ulp_ops->indicate_netevent(). Upstream code no longer uses
this parameter.

Impact: None.

Fixes
-----
1. Problem: SPQ RAMROD type field does not consistently contain the
function ID.

Change: Fixed in cnic_submit_kwqe_16() for HSI 6.0 and above.

Impact: iSCSI in NPAR mode.

bnx2 v2.0.21b (Dec 21, 2010) cnic 2.2.11b (Dec 21, 2010)
=========================================================
Enhancements
------------
1. Change: Call cm_connect_complete() when an invalid path_response
netlink message is received. This will speed up iscsid in
disconnecting the connection. This helps to resolve
CQ49665.

Impact: iSCSI.

bnx2 v2.0.20g (Dec 17, 2010) cnic 2.2.10g (Dec 17, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ51766) cnic driver panics in cnic_service_bnx2() during
iscsid restart.

Cause: Referencing the cp->kcq1 pointer before checking that the device
is up.

Change: Fixed logic so that the cp->kcq1 pointer will only be
refernced after checking the device is up.

Impact: iSCSI.

Enhancements
------------
1. Change: Added retry logic in iscsi_nl_send_msg() to retry netlink
messages to userspace.

Impact: iSCSI.

bnx2 v2.0.20f (Dec 09, 2010) cnic 2.2.10f (Dec 09, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ51544) Unable to connect to iSCSI targets on 57712 NPAR
LOMs with NPAR disabled.

Cause: ff:ff:ff:ff:ff:ff iSCSI MAC address was used in this case.

Change: Add code to detect invalid MAC address and use port MAC address
instead. That's the only to determine NPAR is disabled.

Impact: 57712 iSCSI.

2. Problem: MTU change in INTA mode crashes occasionally.

Cause: Status block may be accessed if INTA is shared with another
device during reset. There is a short period that the status
block is freed.

Change: Free IRQ before freeing status block.

Impact: bnx2 MTU change/ring size change.

3. Problem: Heap corruption reported by VMWare.

Cause: list_del() is called after kfree() in OOO code.

Fix: call list_del() before kfree().

Impact: iSCSI OOO.

bnx2 v2.0.20e (Dec 06, 2010) cnic 2.2.10e (Dec 06, 2010)
=========================================================
Enhancements
------------
1. Change: Adjusted hc timeout for EQ to use the T6.0 value of 4. This
will match T5.x HC timeout values.

Impact: 10G iSCSI only.

2. Change: Minor changes to match upstream code.

Impact: None.

bnx2 v2.0.20d (Nov 16, 2010) cnic 2.2.10d (Nov 16, 2010)
=========================================================
Fixes
-----
1. Problem: VMware NetQueue not working properly on 5709.

Cause: HSI mismatch.

Change: Updated HSI to match T6.0 bnx2 firmware.

Impact: NetQueue on 5709.

Enhancements
------------
1. Change: Adjusted kernel compatibility code to compile on RHEL5.6.

Impact: bnx2 and cnic.

bnx2 v2.0.20c (Oct 28, 2010) cnic 2.2.10c (Oct 28, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49616) NMI occurs during repeated load/unload of bnx2 driver
on 5709.

Cause: The 5709 chip's DMA block wasn't stopped properly before reset.

Change: Fixed by clearing DMA_ENABLE in NEW_CORE_CTL register and
polling for pending bus transactions to stop.

Impact: 5709.

Enhancements
------------
1. Change: Update 5706/5708/5709 firmware to 6.2.1.

Impact: All 1G devices.

2. Change: Fixed one circular lock dependency issue with bnx2i when making
up call to send iSCSI NL message.

Impact: None.

bnx2 v2.0.20b (Oct 13, 2010) cnic 2.2.10b (Oct 13, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49481) pci_enable_pcie_error_reporting failed on
5706 and 5709.

Cause: AER not supported on non-PCIE devices.

Change: Enable AER only on PCIE devices (5709).

Impact: None.

Enhancements
------------
1. Change: (CQ49858) Support KVM pass-through mode by eliminating
config cycles to non-standard PCI registers
(PCICFG_MISC_CONFIG, PCICFG_REG_WINDOW*).

Impact: All chips.

bnx2 v2.0.18c (Sep 13, 2010) cnic 2.2.6c (Sep 13, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49832) bnx2 flow control not working

Cause: Mistakenly disabled in firmware in 2.0.17j to fix CQ46393.

Change: Re-enabled RV2P flow control with additional fixes to
for a number of odd flow control issues. New firmware
versions are 6.0.15 for 5706/5708 and 6.0.17 for 5709.

Impact: 5706/5708/5709.

Enhancements
------------
1. Change: Added zeroing of the iSCSI L2 ring's RX BD page to help
signal ring shutdown to uIP.

Impact: iSCSI.

2. Change: Fix compile issues on 2.6.36 kernel.

Impact: None.

bnx2 v2.0.18b (Sep 02, 2010) cnic 2.2.6b (Sep 02, 2010)
=========================================================
Enhancements
------------
1. Change: Slightly improve the cnic Netlink fix in cnic 2.2.5k.

Impact: iSCSI.

bnx2 v2.0.17l (Aug 19, 2010) cnic 2.2.5l (Aug 19, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49502) - bnx2x_panic_dump doing DHCP and Data/Header Digest

Cause: A mismatch was found in the txbd where the hw prod idx did not
match the sw prod idx (via the vlan_id field). The problem will
show when uIP restarts without cnic reload. Since uIP restarted,
it has lost all previous history about the uio ring.

Change: Added cnic_shutdown_rings to the uio_close path so whenever
uio_open is called from uIP, the rings will start off fresh.

Impact: 570X/5771X iSCSI.

2. Problem: (CQ49211) Connection via bnx2i path fails in SuSE 11 SP1

Cause: For 5708/09, the previous firmware set did not take the l2 frame
header length into account in the placement filter.

Change: Updated to 5706/08 fw 6.0.14 and 5709 fw 6.0.16 which addresses
this issue.

Impact: 570X iSCSI.

bnx2 v2.0.17k (Aug 18, 2010) cnic 2.2.5k (Aug 18, 2010)
=========================================================
Fixes
-----
1. Problem: iSCSI sessions do not recover when running under
heavy stress conditions with the socket layer.

Cause: The NetLink buffer would get congested, so that the response
to the PATH_UPDATE back to uIP would not be delivered.

Change: Use CNIC to throttle the number of outstanding PATH_REQ's
to uIP, easing the congestion on the Netlink buffer.

Impact: 570X/5771X iSCSI.

bnx2 v2.0.17j (Aug 15, 2010) cnic 2.2.5j (Aug 15, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49395) Session recovery occurs during heavy traffic.

Cause: The mapping of the 10g hw context id to l5 cid didn't consider
the port/vfid.

Change: Fixed the 10g hw context id to l5 cid mapping in TCP OOO

Impact: 5771X iSCSI.

2. Problem: (CQ49111) System freezes when unloading bnx2x drivers while
having active sessions.

Cause: The iro_arr was not initialized before deferencing which led to
a kernel panic. This is caused by a race condition between uIP
and cnic.

Change: Moved the initialization of the iro_arr to before uIP can call
uio open.

Impact: 5771X iSCSI.

3. Problem: (CQ49211) 5708/09 Connection via bnx2i path fails SuSE 11 sp1

Cause: For 5709, the fast coalescing algorithm had a bug in the fw.

Change: Updated 5709 MIPS firmware to 6.0.14 which contains a fix for
this issue.

Impact: 5709 iSCSI.

4. Problem: (CQ46393) 5706/08/09 NC-SI Traffic Stops After Host Kernel Panic

Cause: RV2P firmware was set to drop input packets at a rate which is
slower than input line rate when the host stops posting buffers.
This has caused the rxp ftq to backup which eventually led to the
rxp ftq hw to assert PAUSE and flood the network.

Change: RV2P firmware was modified to disable any waiting before dropping
the input packet when the host doesn't post buffers.

Impact: 5706/08/09.

bnx2 v2.0.17i (Aug 09, 2010) cnic 2.2.5i (Aug 09, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49159) 57710 firmware asserts running disktest.

Cause: CSTORM memory corruption.

Change: Do not initialize and use the FCoE EQ on 57710. The memory
offsets for the FCoE EQ ring are not defined on 57710.

Impact: 57710 iSCSI.

2. Problem: (CQ49271) Soft lockup during ifup/ifdown test with active iSCSI
connections.

Cause: rtnl_lock may have a circular dependency with another filesystem
mutex during uio_close().

Change: Removed rtnl_lock() in cnic_uio_close().

Impact: All iSCSI.

bnx2 v2.0.17h (Aug 03, 2010) cnic 2.2.5h (Aug 02, 2010)
=========================================================
Enhancements
------------
1. Change: Enabled new RV2P flow control on all bnx2 devices.

Impact: All bnx2 devices.

2. Change: Suppressed "OOO CQE is empty" kernel message.

Impact: None.

bnx2 v2.0.17g (Aug 02, 2010) cnic 2.2.5g (Aug 02, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49152) cnic driver crashes during iscsid restart.

Cause: cnic_wq destroyed while cnic_delete_task() is still queued
in the workqueue.

Change: Call destroy_workqueue() after cnic_release() which waits
for the cnic_delete_task() to finish.

Impact: 10G iSCSI.

bnx2 v2.0.17f (July 30, 2010) cnic 2.2.5f (July 30, 2010)
=========================================================
Fixes
-----
1. Problem: iSCSI license not read correctly on 57712 in NIC partitioning
mode.

Cause: Missing NIC partitioning license logic.

Change: Added NIC partitioning license logic.

Impact: 10G iSCSI.

Enhancements
------------
1. Change: Updated 5709 firmware to 6.0.13. The new 5709 firmware
has additional rx and tx performance improvements.

Impact: 5709.

bnx2 v2.0.17e (July 29, 2010) cnic 2.2.5e (July 29, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49117, CQ49111) Soft locup when unloading bnx2x with cnic
and bnx2fc/bnx2i loaded.

Cause: cnic_cm_stop_bnx2x_hw() thread under rtnl_lock() and pci_bus_sem
has to wait for cnic_delete_task() to finish the 2-second wait
and CFC DELETE of every FCoE or iSCSI connection. There may
be work structs scheduled on the common workqueue ahead of
cnic_delete_task() that require the same semaphores, leading
to the soft lockup.

Change: Use a dedicated workqueue for cnic_delete_task().

Impact: 10G iSCSI and FCoE.

2. Problem: (CQ49113) Compilation error with bnx2x 1.60.30.
(CQ48828) lediag fails with cnic loaded.

Cause: license_key structure changed to use all 32-bit fields. This
change is to fix CQ48828 (lediag fails with cnic loaded).
16-bit access causes lediag failure.

Change: Made corresponding change to read 32-bit values for the
iSCSI license.

Impact: 10G iSCSI.

3. Problem: (CQ49097) cnic panics when loading on 5708.

Cause: The driver uses NULL OOO ring pointers to initialize OOO
for 5708.

Change: Skip OOO completely on 5708.

Impact: bnx2 iSCSI.

bnx2 v2.0.17d (July 28, 2010) cnic 2.2.5d (July 28, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49071) Soft lockup during system shutdown after logging
in to 10G iSCSI sessions.

Cause: This was introduced in 2.2.5c when fixing CQ49003.
flush_scheduled_work() can deadlock because we're
holding rtnl_lock and linkwatch_event may be on the
workqueue.

Change: Fixed by using flags to wait for the cnic_delete_task()
to finish.

Impact: 10G iSCSI.

2. Problem: cnic driver does not load on 5708 devices.

Cause: Bug in driver that skips devices without OOO support.

Change: OOO setup has been changed so that cnic initialization will
continue even if OOO fails for whatever reason on all chips.

Impact: iSCSI.

Enhancements
------------
1. Change: Updated 5708 firmware to 6.0.11 and 5709 firmware to
6.0.12. The new 5709 firmware fixes small packet rx
performance issue. Some adiitional fixes for iSCSI
and OOO.

Impact: All bnx2 chips.

bnx2 v2.0.17c (July 23, 2010) cnic 2.2.5c (July 23, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ49003) Panic in cnic_free_bnx2x_conn_resc() during
ifdown with many 10G iSCSI active sessions.

Cause: cancel_work_sync() is not available in RHEL5.x kernels to
wait for cnic_delete_task() to finish before freeing
the device's data structures (in particular the csk table).

Change: Use flush_scheduled_work() to wait instead.

Impact: 10G iSCSI on older kernels (e.g. RHEL5.x)

Enhancements
------------
1. Change: Added AER (Advanced Error Reporting) on bnx2.

Impact: None.

bnx2 v2.0.17b (July 20, 2010) cnic 2.2.5b (July 20, 2010)
=========================================================
Fixes
-----
1. Problem: Still seeing uio_release panics during ifup/ifdown test.

Cause: UIO device unregistered prematurely.

Change: Do not unregister UIO devices until rmmod.

Impact: iSCSI.

Enhancements
------------
1. Change: Various upstream patches. Please see ChangeLog for details.

bnx2 v2.0.16d (July 14, 2010) cnic 2.2.4d (July 14, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ44916) Unload bnx2/bnx2x fails after connecting to
iSCSI targets.

Cause: UIO device deleted before userspace has closed the device,
causing various failures including kernel panic.

Change: Separated UIO structure from cnic_dev structure so that
we can wait until UIO is closed before unregister and deleting
UIO.

Impact: iSCSI. This change should have possitive impact on ifup/ifdown,
MTU change/selftest/hotplug/etc with active iSCSI sessions.

Enhancements
------------
1. Change: Allocate the actual number of MSI-X vectors instead of always
9. Also, keep trying if the number of vectors is less than
the desired number.

Impact: 5709 networking and iSCSI.

bnx2 v2.0.16c (July 12, 2010) cnic 2.2.4c (July 12, 2010)
=========================================================
Enhancements
------------
1. Change: Added VLAN_TAG_PRESENT to distinguish between physical and
VLAN netevents in cnic.

Impact: FCoE.

bnx2 v2.0.16b (July 8, 2010) cnic 2.2.4b (July 8, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ48753) cnic will not compile with bnx2x 1.60.27.

Cause: IGU symbols not defined without ELINK_DEBUG defined.

Change: Added ELINK_DEBUG.

Impact: None.

2. Problem: (CQ48717) Kernel panic in bnx2x during ifdown with active iSCSI
sessions.

Cause: uio_close() is called after the device is already down. bnx2x
will crash when we try to shutdown the iSCSI ring.

Change: Shutdown the iSCSI ring even if uio_close() is not called in
the shutdown path.

Impact: 10G iSCSI.

Enhancements
------------
1. Change: Always run in MSI-X mode on 5709.

Impact: 5709.

2. Change: Added wait of 2 seconds when sending PATH_REQ if UIO has not
been opened yet. This improves the liklihood of login success
during the first login if using older iscsid.

Impact: iSCSI.

bnx2 v2.0.15k (July 1, 2010) cnic 2.2.3k (July 1, 2010)
=========================================================
Fixes
-----
1. Problem: Compile problems on various older kernels.

Cause: pci_save_state()/pci_restore_state incompatibility in older
kernel. DECLARE_PCI_UNMAP_ADDR() caused dma mapping
field to be undefined on kernels not using IOMMU.

Change: Do not use pci_save_state()/pci_restore_state() on older
kernels. Use dma_addr_t to declare mapping fields.

Impact: None.

bnx2 v2.0.15j (June 30, 2010) cnic 2.2.3j (June 30, 2010)
=========================================================
Fixes
-----
1. Problem: bnx2x firmware asserts if cnic is loaded on 57711E (MF)
functions 2 and higher and the device is brought up.

Cause: Statistics for iSCSI ring not implemented, casuing firmware to
assert when the iSCSI ring is initialized.

Change: Do not enable statistics if the clien ID is bigger than
MAX_STAT_COUNTER_ID.

Impact: bnx2x iSCSI on 57711E.

2. Problem: cnic terminations for iSCSI and FCoE connections may panic or
hang during repeated ifdown/ifup.

Cause: Data structures may be freed while cnic is still waiting for the
2 second CFC_DELETE wait time.

Change: Use cancel_work_sync() to wait for the completion of the
cnic_delete_task(). Check that the CTX_FL_DELETE_WAIT flag
has been set before waiting.

Impact: bnx2x iSCSI and FCoE.

3. Problem: (CQ48642) Compile errors on older kernels.

Cause: VMWARE_ESX_DDK_VERSION not defined in Linux.

Change: Added check for VMKLNX.

Impatc: None.

bnx2 v2.0.15i (June 30, 2010) cnic 2.2.3i (June 30, 2010)
=========================================================

Enhancements
------------
1. Change: Added iSCSI out-of-order support.

Impact: iSCSI.

bnx2 v2.0.15h (June 18, 2010) cnic 2.2.3g (June 10, 2010)
=========================================================
Enhancements
------------

Impact: RSS on 5709.

2. Change: Updated to 6.0.10 firmware.

Impact: all chips.

bnx2 v2.0.15g (June 10, 2010) cnic 2.2.3g (June 10, 2010)
=========================================================
Enhancements
------------
1. Change: Added FCoE statistics SPQ command.

Impact: FCoE.

bnx2 v2.0.15f (June 4, 2010) cnic 2.2.3f (June 4, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ46648) CID leaks while running iLAB 5.12 connection closure
test.

Cause: Race condition between bnx2i initiated TCP close and an
asynchronous RESET_COMP from firmware.

Change: Re-structured cnic code that handles close, abort, and various
completion events to ensure all scenarios are accounted for
with no race conditions.

Impact: All iSCSI connection termination scenarios.

Enhancements
------------
1. Change: Added host iSCSI IP address to the cnic_dev structure so that
bnx2i can report it to sysfs. This is needed for iSCSI boot
during pivot_root.

Impact: iSCSI boot.

bnx2 v2.0.15e (June 3, 2010) cnic 2.2.3d (June 2, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ48133) bnx2 fails to compile on older 2.6 kernels.

Cause: PCI MSIX attributes not defined in kernel .h files.

Change: Added compatibility code.

Impact: None.

bnx2 v2.0.15d (June 2, 2010) cnic 2.2.3d (June 2, 2010)
=========================================================
Fixes
-----
1. Problem: (CQ47942) rmmod hangs if the device has been opened and closed
more than once.

Cause: netif_napi_add() called once during every ->open().
netif_napi_del() is only called once during rmmod.

Change: Call netif_napi_del() in ->close().

Impact: None.

bnx2 v2.0.15c (May 21, 2010) cnic 2.2.3c (April 21, 2010)
=========================================================
Fixes
-----
1. Problem: service iscsid restart on 5709 does not work.

Cause: Not restarting KWQ correctly due to stale context.

Change: Fixed by correctly zeroing KWQ/KCQ/RX context
memory.

Impact: bnx2 iSCSI.

2. Problem: iSCSI license not read correctly on 57711E in single
function mode.

Cause: Bug in reading the mf_cfg block.

Change: Bug fixed.

Change: 57711E iSCSI.

Enhancements
------------
1. Change: Added GRO support.

Impact: All devices on kernels supporting GRO.

bnx2 v2.0.15b (May 12, 2010) cnic 2.2.3b (April 12, 2010)
=========================================================
Fixes
-----
1. Problem: iSCSI does not work on 57712.

Cause: License checking always disabled on 57712.

Change: Added proper checking for 57712 iSCSI license.

Impact: None.

2. Problem: (CQ47360) Compile errors on older kernels not supporting
UIO and latest iSCSI.

Cause: New cnic driver will only compile on kernels newer than
2.6.31 and some selected distros that have the backport.

Change: Makefile changes to compile cnic only on supported kernels.

Impact: None.

Enhancements
------------
1. Change: Changed bnx2_cnic_probe() to bnx2_cnic_probe2() so
that out-of-tree driver componenets will not inter-
operate with upstream components. This avoids
compatibility problems that often lead to kernel
crashes.

Impact: Out-of-tree cnic will not operate with upstream
L2 drivers and vice versa.

2. Change: Revert the PRS_REG_NIC_MODE change done in 2.0.11h. Newer
bnx2x driver (1.60.18+) do not require this setting.

Impact: None.

bnx2 v2.0.14b (April 28, 2010) cnic 2.2.2b (April 28, 2010)
============================================================
Enhancements
------------
1. Change: Added compatibility code for RHEL5.4+ kernels.

Impact: None.

2. Change: Added VLAN ID to netdev event callback.

Impact: bnx2i.

bnx2 v2.0.13b (April 22, 2010) cnic 2.2.1c (April 30, 2010)
============================================================
Enhancements
------------
Add debug code to dump all KWQE's (RAMROD) posted to 5771x chipset.
This feature can be enabled/disabled using module parameter, by default
this feature is disabled. Also a exported function is introduced to
dump 3 pages worth of KCQE's

bnx2 v2.0.13b (April 22, 2010) cnic 2.2.1b (April 22, 2010)
============================================================
Enhancements
------------
1. Change: cnic has been updated to be similar to the upstream versions
using UIO with added T6.0 iSCSI support for 10G and other bug
fixes.

Impact: iSCSI now requires UIO, new bnx2i, and bnx2x 1.60.16+.

bnx2 v2.0.11j (April 22, 2010) cnic 1.10.2j (April 22, 2010)
============================================================
Fixes
-----
1. Problem: (CQ47298) Does not compile with bnx2x 1.60.16.

Cause: cnic_if.h has changed.

Change: Updated code to be compatible with new cnic_if.h.

Impact: None.

bnx2 v2.0.11i (April 15, 2010) cnic 1.10.2i (April 15, 2010)
============================================================
Fixes
-----
1. Problem: (RHBZ 511368) Driver loses one MSI-X vector after many hours
of traffic.

Cause: Chip timing out on write cycle to the MSI-X mask bit, causing
the unmask operation to be dropped.

Change: Increase GRC timeout in register 0x8cc.
(Same fix from 2.0.8e).

Impact: bnx2x MSI-X mode.

2. Problem: (RHBZ 554706) scheduling while atomic warning when bonding and
VLANs are used with cnic loaded.

Cause: bond_del_vlans_from_slave() holds bond->lock when calling
ndo_vlan_rx_register(). bnx2 calls bnx2_netif_stop() to
stop the rx handling while changing the vlgrp. The call
also calls bnx2_cnic_stop() which has many sleeping functions.

Change: Do not stop cnic when VLANs are changed. Since there is no
reset during VLAN change, there is no need to stop cnic.
(Same fix from 2.0.8e).

Impact: VLAN and iSCSI.

3. Problem: (CQ46940) Poor small packet performance on 5709.

Cause: FTQ discards caused by bottlenecks in firmware.

Change: Upgraded to 5.0.0.j15 MIPS firmware for 5709.
(Same fix from 2.0.8c)

Impact: 5709.

Enhancements
------------
1. Change: Improved rx performance by prefetching next entry's descriptor
header and SKB.

Impact: All chips.

2. Change: Updated cnic interface to support out-of-order processing. This
is needed for bnx2x 1.60.15 but the feature is not available in
cnic yet.

Impact: None.

bnx2 v2.0.11h (Mar 29, 2010) cnic 1.10.2h (Mar 29, 2010)
========================================================
Fixes
-----
1. Problem: iSCSI not functional with bnx2x 1.60.11.

Cause: PRS_REG_NIC_MODE set to 1, causing L2 to receive iSCSI traffic.

Change: Cleared PRS_REG_NIC_MODE.

Impact: bnx2x iSCSI.

bnx2 v2.0.11g (Mar 17, 2010) cnic 1.10.2g (Mar 17, 2010)
========================================================
Enhancements

Impact: bnx2x iSCSI.

2. Change: Added new igu status block ID to handle iSCSI status
block acknowledgement in T6.0 HSI.

Impact: bnx2x iSCSI.

3. Change: Allow multiple ethtool speed advertisments when using
newer ethtool 6.

Impact: ethtool -s.

Fixes
-----
1. Problem: Statistics 64-bit counters may not be accurate after MTU
change.

Cause: Bug missing the carry when summing 64-bit counters.

Change: Fixed the missing carry.

Impact: statistics.

Impact: bnx2x iSCSI.

bnx2 v2.0.8e (April 13, 2010) cnic 1.9.13b (Dec 16, 2009)
=========================================================
Fixes
-----
1. Problem: (RHBZ 511368) Driver loses one MSI-X vector after many hours
of traffic.

Cause: Chip timing out on write cycle to the MSI-X mask bit, causing
the unmask operation to be dropped.

Change: Increase GRC timeout in register 0x8cc.

Impact: bnx2x MSI-X mode.

2. Problem: (RHBZ 554706) scheduling while atomic warning when bonding and
VLANs are used with cnic loaded.

Cause: bond_del_vlans_from_slave() holds bond->lock when calling
ndo_vlan_rx_register(). bnx2 calls bnx2_netif_stop() to
stop the rx handling while changing the vlgrp. The call
also calls bnx2_cnic_stop() which has many sleeping functions.

Change: Do not stop cnic when VLANs are changed. Since there is no
reset during VLAN change, there is no need to stop cnic.

Impact: VLAN and iSCSI.

bnx2 v2.0.8d (April 02, 2010) cnic 1.9.13b (Dec 16, 2009)
=========================================================
Enhancements

=======================================================
Fixes
-----
1. Problem: (CQ44964) RHEL5.4 crashes when bnx2 driver is updated with
out-of-tree version.

Cause: Newer out-of-tree driver's cnic_eth_dev structure has been
updated, making it incompatible with RHEL5.4's cnic driver.

Change: Reverted the structure update for RHEL5.4.

Impact: None.

Enhancements
------------
1. Change: Improved the reset logic to prevent NETDEV WATCHDOG when
TSS is enabled.

Impact: MTU change, ring size change, selftest, etc.

2. Change: Fixed some compiler warnings when compiling bnx2 and cnic
drivers.

Impact: None.

bnx2 v2.0.7b (Dec 7, 2009) cnic 1.9.12b (Dec 7, 2009)
=======================================================
Fixes
-----
1. Problem: (CQ44620) Spurious KCQ entries leading to bnx2x assert.

Cause: Stale status block with old KCQ index after restarting hardware.

Change: Added some additional cleanup and initialization steps including
zeroing the status block.

Impact: None.

Enhancements
------------
1. Change: Updated RV2P P1 for 5709 to 5.0.0.j10 to address a flow control
issue that can lead to context corruption. Flow control
watermarks have also been optimized.

Cause: cnic_lock mutex has circular dependency, causing deadlock
when iscsid tries to cleanup connections.

Change: Merged in upstream cnic patches to avoid circular
dependency.

Impact: None.

Enhancements
------------
Change: (CQ43088) Changed the firmware version string format.

Impact: None.

2. Problem: (CQ44399) iLAB 5.10 connection establishment test failure.

Cause: Firmware SYN-ACK handling issue.

Change: Updated firmware to 5.0.0.j6 in bnx2_fw.h and 5.0.0.j9 in
bnx2_fw2.h.

Impact: iSCSI.

Enhancements
------------
Change: (CQ43088) Added VPD-R V0 firmware version string to ethtool -i.

Impact: None.

bnx2 v1.9.39b (Nov 6, 2009) cnic 1.9.10b (Nov 12, 2009)
=======================================================
Fixes
-----
1. Problem: (CQ44470) Kernel panics when bnx2/bnx2x is unloaded with
active iSCSI sessions.

Cause: NETDEV_UNREGISTER will cause bcm570x_* transport to be
destroyed while sessions may still be active.

Change: Use module referencing to prevent bnx2/bnx2x from unloading.
This is a simple interim solution to revert back to the
old behavior. In T6.0, we will migrate to the upstream
driver architecture and network drivers will be able to be
unloaded again.

Impact: None.

Enhancements
------------
Change: Added a short register dump during NETDEV_WATCHDOG.

Impact: None.

bnx2 v1.9.38b (Nov 6, 2009) cnic 1.9.9b (Nov 6, 2009)
=====================================================
Fixes
-----
1. Problem: (CQ44446) cnic panics during 10G iSCSI initialization.

Cause: Recent interface changes introduced this regression.
cnic_service_bnx2x() panics when accessing uninitialized
status block pointer.

Change: Added state checking in cnic_service_bnx2x().

Impact: None.

2. Problem: (CQ44439) bnx2 does not compile on older 2.6 kernels.

Cause: mutex not defined on older kernels.

Change: Use rtnl_lock() to protect bnx2_reset_task().

Impact: None.

bnx2 v1.9.37b (Nov 4, 2009) cnic 1.9.8b (Nov 3, 2009)
=====================================================
Enhancements
------------

1. Change: Updated 5708/5706 firmware to 5.0.0.j5 for better small packet
performance.

Impact: 5706/5708.

Fixes
-----
1. Problem: (CQ43280) Cannot unload cnic after bnx2/bnx2x is loaded.

Cause: module referencing.

Change: Changed module referencing scheme.

Impact: None.

bnx2 v1.9.36b (Oct 22, 2009)
=======================================================
Enhancements
------------

1. Change: Expand on NetQueue module parameters.

Impact: bnx2 VMware NetQ.

bnx2 v1.9.35b (Oct 22, 2009)
=======================================================
Fixes
-----
1. Problem: If only 1 queue is used on VMware ESX, iSCSI
offload would fail.

Cause: The inboxed VMware driver would only use
1 MSI-X vector. Because of this the driver
would not setup MSI-X

Change: Always setup MSI-X reguardless of the
number of MSI-X vectors used.

Impact: 5709 iSCSI on VMware

bnx2 v1.9.34b (Oct 20, 2009)
=======================================================
Fixes
-----
1. Change: Updated xinan firmware to 5.0.0.j8
Nop timeout tuning (VMware PR467194)
Added a new data fw heartbeat to work with
the new bootcode and also handle older
bootcode.

Impact: 5709.

bnx2 v1.9.33b (Oct 8, 2009)
=======================================================
Enhancements
------------

1. Change: Make NetQueue module parameters more explict.

Impact: bnx2 VMware NetQ.

bnx2 v1.9.32b (Oct 8, 2009) cnic v1.9.7c (Oct 8, 2009)
=======================================================
Fixes
-----
1. Problem: CNIC unable to handle an unsolicited
RESET COMPLETE which would result in a hung
session.

Cause: The CNIC driver couldn't handle unexpected SYN.

Change: The CNIC driver will now handle an unsolicited
RESET COMPLETE and cleanup properly.

Impact: cnic

Enhancements
------------

1. Change: Allow the default NetQueue options to be
controlled through the macro,
BNX2_ENABLE_NETQUEUE.

Impact: bnx2 VMware NetQ.

bnx2 v1.9.31b (Oct 6, 2009)
=======================================================
Fixes
-----
1. Problem: PSOD would occur when alloc()'ing NetQueue's

Cause: With the removal of the global 'disable_netq'
parameters, the NetQueue CID's weren't being
mapped in some cases

Change: Always map the NetQueue CID's

Impact: bnx2 VMware ESX NetQueue

bnx2 v1.9.30b (Oct 5, 2009)
=======================================================
Fixes
-----
1. Problem: PSOD would occur because of TX timeouts

Cause: The VMware netdev watchdog timer was ran before
the reset task got a chance to run on a loaded
system.

Change: Elongated the TX timeout value for VMware ESX
only to allow for the reset task to run.

Impact: bnx2 VMware ESX

Enhancements
------------

1. Change: Updated vmkernel module parameter, 'force_netq',
to allow NetQueue setting to be adjusted per
function rather then globally for all functions.

Impact: bnx2 VMware ESX

bnx2 v1.9.29b (Oct 1, 2009)
=======================================================
Fixes
-----
1. Change: Updated xinan firmware to 5.0.0.j7 and
teton firmware to 5.0.0.j4 which will fix
L2 hang due to iSCSI PDU's padding byte
extended to another TCP segment

Impact: 5706/5708/5709.

bnx2 v1.9.28b (Sep 25, 2009)
=======================================================
Fixes
-----
1. Change: Updated firmware to 5.0.0.j6 which will add
the corresponding flow control trip point.

Impact: 5709.

bnx2 v1.9.27b (Sep 24, 2009) cnic v1.9.7b (Sep 24, 2009)
=======================================================
Fixes
-----
1. Problem: For the cnic users would see in the kernel logs:

"kcq abs(hw_prod(0) - sw_prod(65534)) >
MAX_KCQ_IDX(2047)"

Cause: The function was not taking into account the
wrapping of the software and hardware producer
indexes.

Change: Recaculate the difference between the index with
wrapping taken into account.

Impact: cnic

Enhancements
------------

1. Change: Updated firmware to 5.0.0.j5 which increased the
rxpq depth from 32 to 256 to enhance the performance
on systems without flow control.

Impact: 5709.

bnx2 v1.9.26c (Sep 17, 2009)
=======================================================
Enhancements
------------
1. Change: Cleanup the VMware NetQueue code. Eliminate unneeded
RX flush routine, fix the number of queues to be the
same on 1500 and 9000 MTU sized packets.

Impact: bnx2 VMware NetQ.

bnx2 v1.9.26b (Sep 14, 2009)
=======================================================
Fixes
-----
1. Problem: VMware PSOD on MTU change

Cause: MSI-X window was remapped to the beginning of the PCI
config space. The driver would disable the bar space
because the MSI-X window was remapped incorrectly. This
would eventually cause a PSOD.

Change: Before the chip reset, the driver would disable MSI-X,
after the chip reset, MSI-X is re-enabled.

Impact: VMware NetQueue

bnx2 v1.9.25b (Aug 21, 2009) cnic v1.9.6 (Aug 21, 2009)
=======================================================
Fixes
-----
1. Problem: (CQ 43182/43252) Compile error on RHEL4

Cause: struct mutex not defined on older kernels.

Change: Wrap cnic_lock mutex structure and code with #ifdef BCM_CNIC.

Impact: None.

2. Problem: Unloading cnic after ifdown may crash.

Cause: cnic unregisters with bnx2/bnx2x twice.

Change: Fixed logic to unregister only once.

Impact: None.

bnx2 v1.9.24b (Aug 13, 2009) cnic v1.9.6 (Aug 13, 2009)
=======================================================
Fixes
-----
1. Problem: (CQ 42778) Kernel occasionally panics when enabling jumbo
frames.

Cause: If the driver is unable to allocate memory for the buffers,
the device is not properly shutdown.

Change: Added logic to shutdown device if unable to allocate buffers
and complete the setup of the device.

Impact: bnx2, changing MTU and ring sizes.

Enhancements
------------
1. Change: Updated firmware to 5.0.0.j3 for better small packet rx
performance. Firmware also fixes header digest error during
I/O.

Impact: All bnx2 devices.

bnx2 v1.9.23b (July 29, 2009) cnic v1.9.5 (July 29, 2009)
==========================================================

Fixes
-----
1. Problem: (CQ 42723) KCQ not resetting to 0 problem

Cause: RCU deadlock during shutdown

Change: Move the bnx2_register_cnic() call out of the
above sequence. Instead, register and
unregister during NETDEV_UP/NETDEV_DOWN events.

Change all slow path RCU read locks to mutex.
In cnic, we also use reference counting to
protect some slow paths.

Impact: bnx2 iSCSI, bnx2x iSCSI

bnx2 v1.9.22b (July 23, 2009) cnic v1.9.4 (July 23, 2009)
==========================================================

Enhancements
------------
1. Change: If a TX timeout occurs, there could be the possiblity that the
chip is hung. By printing chip state into the kernel ring buffer,
it will be easier to determine this.

Impact: bnx2 iSCSI.

2. Change: The bnx2 firmware should always be matched with the proper bnx2
driver. The bnx2 firmware version string are now printed.
It will be easier to identify the running firmware.

Impact: bnx2

3. Change: When a TX timeout occurs and the chip is reset, the ability to
debug the chip further is lost. This is because the chip state
information is lost during the reset. The users have a choice
to prevent the chip reset.

Impact: bnx2

4. Change: Add a check to see if there was a KCQ overflow was
in the bnx2x firmware. Now this check has been moved to the
CNIC so that the driver could control the cleanup/recovery.

Impact: bnx2 iSCSI.

bnx2 v1.9.21b (July 16, 2009)
==========================================================
Enhancements
------------
1. Change: Updated firmware to 5.0.0.j2 to fix remote reset problem

Impact: bnx2 iSCSI.

bnx2 v1.9.20b (July 09, 2009), cnic v1.9.3 (July 09, 2009)
==========================================================
Fixes
-----
1. Problem: (CQ42534) cnic.c does not compile on older kernels.

Cause: Some iscsi_proto constants not defined in

Change: Added the constant definitions if not already defined.

Impact: None.

Enhancements
------------
1. Change: Updated firmware to 5.0.0.j to fix TMF releated iSCSI issues.

Impact: bnx2 iSCSI.

bnx2 v1.9.19b (July 01, 2009), cnic v1.9.2 (July 01, 2009)
==========================================================
Fixes
-----
1. Problem: (CQ42399) 10G iSCSI fails when initiator and target MTUs
don't match.

Cause: cnic driver sets the MSS without knowing the actual MSS
option and timestamp option during TCP connection.

Change: Changed driver to set MSS to 0xffff so that firmware can
calculate MSS on its own.

Impact: bnx2x iSCSI.

2. Problem: 1G iSCSI fails when initiator and target MTUs don't
match and timestamp is enabled.

Cause: Firmware was not adjusting for the 12-byte timestamp option
if MSS was reduced by MSS option.

Change Updated firmware to 5.0.0.i

Impact: bnx2 iSCSI.

3. Problem: (CQ42353) Unable to disable TCP timestamp on 10G iSCSI.

Cause: Timestamp was hardcoded to be enabled for 10G.

Change: Update global timestamp option during each TCP connection.

Impact: bnx2x iSCSI.

4. Problem: (CQ42329) bnx2x MC assert during IPv6 login/logout.

Cause: EQ filled with more than 128 L4 kcqes without MSI-X interrupt
for 2 seconds. The driver can only buffer 128 L4 kcqes.

Change: Increased L4 kcqe buffer to 256 entries as a temporary solution.
Need to understand the delayed interrupt issue.

Impact: None.

bnx2 v1.9.18b (June 25, 2009), cnic v1.9.1 (June 24, 2009)
==========================================================
Enhancements
------------
1. Change: Added FTQDiscard counter to the list of counters being
reported. During small packet test, there may be FTQ
overflow and this counter is very useful.

Impact: None.

2. Change: Updated firmware to 5.0.0.h to improve small packet L2
performance and to enhance iSCSI TMF handling.

Impact: 5706/5708/5709.

bnx2 v1.9.17b (June 24, 2009), cnic v1.9.1 (June 24, 2009)
==========================================
Fixes
-----
1. Problem: Leaking NetQueues if the firmware did not respond in time

Cause: System might be clogged and there is not enough time to
process the KCQ

Change: Updated driver/firmware to allow the calling of the free RX
queue request before a RX alloc request is issued

Impact: 5709

2. Problem: An offloaded iSCSI connection would get stuck

Cause: Issing an offload request might fail, and this was not handled
properly.

Change: Updated driver/firmware to return the proper return code and
handle offload connection failures.

Impact: 5706/5708/5709

3. Problem: tasklet_init() is being called on a task that is scheduled

Cause: When the CNIC calls register_device(), that task might already
be schedled.

Change: tasklet_disable() is insufficient because the tasklet remains
scheduled and stays on the tasklet list, instead tasklet_kill()
is now used.

Impact: 5706/5708/5709

bnx2 v1.9.16b (June 10, 2009), cnic v1.9.0 (June 10, 2009)
==========================================================
Enhancements
------------
1. Change: (CQ38228) Use symbol_get() for ipv6 symbols so that the
cnic driver will load without necessarily loading ipv6
modules.

Impact: iSCSI over IPv6.

2. Change: Updated 5706/08/09 MIPS firmware to 5.0.0.g.

Impact: 5706/08/09.

3. Change: Backported some dma_mapping_error() checking.

Impact: None.

bnx2 v1.9.15b (June 1, 2009), cnic v1.8.6 (June 1, 2009)
========================================================
Enhancements
------------
1. Change: Upstream bnx2 tx path optimizations. Please see ChangeLog.

Impact: bnx2 tx path.

2. Change: In the cnic driver, save the last allocated TCP port during
unregistration so that previously used TCP ports will not
be immediately re-used.

Impact: iSCSI.

3. Change: VMWare TCP port allocation changes.

Impact: VMWare iSCSI.

bnx2 v1.9.14b (May 21, 2009)
==========================================
Fixes
-----
1. Problem: NOPOUT timeouts on 570x iSCSI connections.

Cause: Bugs in TCP timestamp implementation.

Change: Updated MIPS firmware to 5.0.0.f.

Impact: 5706/5708/5709.

bnx2 v1.9.13b (May 18, 2009)
==========================================
Fixes
-----
1. Problem: Potentially exceeding the NetQueue limit recommendations
by VMware which could stress system resources

Cause: When system resources are strained.

Change: There are now limits on the number of NetQueues which the
driver will request:
When the MTU is 1500 the max number of queues per port is 8
When the MTU is 9000 the max number of queues per port is 4

Impact: NetQueue enabled version of VMware ESX

2. Problem: Getting conflicting NetQueue and iSCSI completions

Cause: When MSI-X is not used on a 5709, NetQueue is still enabled

Change: NetQueue is not disabled is MSI-X is not used.

Impact: NetQueue enabled version of VMware ESX

bnx2 v1.9.12b (May 13, 2009)
==========================================
Fixes
-----
1. Problem: Potentially returning a negative number of NetQueues

Cause: When calculating the number of rings, we use the calculation from
the number of msi-x vectors returned, The number of NetQueues
returned could potentially be negitive if only 1 vector was
returned. This is because the driver was subtracting 2
instead of subtracting 1 (for the default queue) from the total
number of rings.

Change: Return the proper number of queues not including the default
queue.

Impact: NetQueue enabled version of VMware ESX

bnx2 v1.9.11b (May 12, 2009), cnic v1.8.5 (May 13, 2009)
========================================================
Fixes
-----
1. Problem: TCP Delay ACK not working on bnx2x iSCSI

Cause: Disabled in cnic driver.

Change: Fixed csk->tcp_flags definitions and enabled the proper storm
bit for delay ACK.

Impact: bnx2x iSCSI.

bnx2 v1.9.11b (May 12, 2009)
==========================================
Fixes
-----
1. Problem: iSCSI timestamp TCP option not working.

Cause: Disabled in firmware.

Change: Updated to 5.0.0e MIPS firmware.

Impact: 5709.

bnx2 v1.9.10b, cnic v1.8.4 (May 11, 2009)
==========================================
Fixes
-----
1. Problem: NetQ and iSCSI do not work in Vmware environment.

Cause: 1. cnic driver is overwriting CP and COM mailbox bit values newly
defined to support multiple kcqs.

2. Firmware is completing some iSCSI kcqes on the NetQ's kcq.

Change: Fixed cnic driver to only set and clear bit 0 of the CP
and COM mailbox.

Firmware has been updated to 5.0.0d. This firmware also
supports TCP timestamp option for iSCSI connections.

Impact: 5706/5708/5709 iSCSI, NetQ.

bnx2 v1.9.9b (May 1, 2009)
==========================================
Fixes
-----
1. Problem: There is link, but can't pass traffic on ESXi

Cause: Bits in the RX context are being trampled during the
renegotiation of the link.

Change: RX context offset 0x6 should only be initialized once
during init and not be updated during run-time. Offset
4 contains the BIDX that's mapped to the mailbox.

Impact: VMware with NetQueue

bnx2 v1.9.8b, cnic v1.8.2 (April 27, 2009)
==========================================
Enhancements
------------
1. Change: Updated cnic driver to support 1.50.x HSI as well as the older
1.48.107 HSI. A compile flag will be used to select one or the
other.

Impact: iSCSI on bnx2x.

2. Change: Spec file and Makefile changes detect the proper module
install directory.

Impact: installation.

bnx2 v1.9.7b, cnic v1.8.1 (April 22, 2009)
==========================================
Fixes
-----
1. Problem: Compile error with redfinition of struct kwqe.

Cause: Both the CNIC and bnx2 defined this structure.

Change: Because the bnx2 definition is L2 specific, it was renamed to
struct l2_kwqe.

Impact: None.

2. Problem: Add context memory DMA alignment for 57710.

Cause: For the 57710 context memory needs to be 16k aligned.
Without this alignment you will see errors when trying to
establish more then 5 iSCSI connections on VMware ESX 4.0 U1.

Change: Properly aligned the context memory by allocating a bigger
chunk of memory and then finding the proper alignment.
This reduces the number of possible connections in half
but now we can properly establish more then 5 connections
on VMware.

Impact: iSCSI.

bnx2 v1.9.6b (April 17, 2009)
=============================
Enhancements
------------
1. Change: Added NetQueue support for VMware.

Impact: 5709.

bnx2 v1.9.5b (April 17, 2009)
=============================
Enhancements
------------
1. Change: Updated to 5.0.0.a firmware with NetQ support and iSCSI max
connection license information. RV2P firmware unchanged:
4.6.16 for 5706, 4.6.15 for 5709.

Impact: All chips.

2. Change: Set USE_INT_PARAM on 5709. This will switch the chip in
use "interrupt mode" coalescing after MSI/MSI-X.

Impact: 5709.

3. Change: Included 5706 when doing statistics block DMA workaround.

Impact: 5706.

bnx2 v1.8.8b (March 12, 2009)
=============================
Enhancements
------------
1. Change: Updated to latest 4.6.17 CP firmware for 5709.

Impact: iSCSI licensing on 5709.

bnx2 v1.8.7b, cnic v1.7.8 (March 10, 2009)
==========================================
Enhancements
------------
1. Change: Reverted 5706/5708 firmware to 4.6.16. Low latency interrupt
mode does not work on 5706/5708.

Impact: None.

2. Change: VMWare changes to expose max. number of iSCSI connections in
the cnic_device structure.

Impact: VMware iSCSI.

Fixes
-----
1. Problem: (CQ39867) Compile error on RHEL5.3 Xen kernel.

Cause: msi related symbols undefined because CONFIG_PCI_MSI is not
enabled on Xen kernels.

Change: Added CONFIG_PCI_MSI around the msi related code.

Impact: None.

2. Problem: (CQ39818) iSCSI targets do not reconnect after running self test.

Cause: Interrupt is disabled by bnx2 before notifying CNIC to clean up
and stop. As a result, bnx2i will not receive interrupts when
closing the connections if sharing INTA/MSI with network.

Change: Disable interrupt after notifying CNIC to stop.

Impact: iSCSI.

bnx2 v1.8.6b, cnic v1.7.7 (March 2, 2009)
=========================================
Enhancements
------------
1. Change: Updated to new 5706 firmware (4.6.17) and 5709 firmware (4.6.16).
New interrupt coalescing mode for improved latency and iSCSI
cache line fix on 5709.

Impact: All bnx2 chips.

2. Change: CNIC iSCSI changes for VMWare.

Impact: VMWare only.

bnx2 v1.8.5b, cnic v1.7.6 (Feb 9, 2009)
=======================================
Fixes
-----
1. Problem: (CQ39380) bnx2x iSCSI license not read correctly.

Cause: Using wrong variable to check the license.

Change: Fixed the logic.

Impact: bnx2x iSCSI.

2. Problem: Driver accesing MMIO registers during VLAN operations when
the device is in D3hot state in older kernels.

Cause: VLAN registration functions do not check for device state.

Change: Added if_running check before MMIO access in VLAN registration
functions.

Impact: VLAN operations on all bnx2 chips.

Enhancements
-----------
1. Problem: Updated 5706/5708 firmware to 4.6.16.

Impact: 5706/5708.

bnx2 v1.8.4b, cnic v1.7.5 (Jan 30, 2009)
========================================
Fixes
-----
1. Problem: (CQ39281) Management firmware stops passing traffic when
bnx2 driver is loaded with jumbo frames enabled.

Cause: Firmware bug.

Change: Updated to 4.6.15 firmware.

Impact: 5706/5708/5709.

2. Problem: iSCSI does not work on 57711 in single function mode.

Cause: Driver only allows iSCSI on 57711 if iSCSI is enabled.

Change: iSCSI config. not required in single function mode.

Impact: bnx2x iSCSI.

Enhancements
------------
1. Change: (CQ38576) Add 5709 to bnx2.4 man page.

Impact: None.

bnx2 v1.8.3b, cnic v1.7.4 (Jan 23, 2009)
========================================
Fixes
-----
1. Problem: (CQ38610, CQ39000, CQ39015, CQ39071, CQ39133) Various Jumbo
frames related data corruption issues.

Cause: Bug in RV2P firmware causing jumbo frames to be DMA'ed without
the frame header control structure occasionally.

Change: New firmware.

Impact: 5706/5708/5709.

bnx2 v1.8.2c, cnic v1.7.4 (Dec 30, 2008)
========================================
Fixes
-----
1. Problem: (CQ38955) Xen kernel panic when unloading bnx2 with jumbo MTU.

Cause: Bug in bnx2_free_rx_mem(). The jumbo page ring memory was
freed incorrectly using the wrong local variable as array
index.

Change: Fixed bug by using the correct variable as array index.

Impact: Jumbo frames.

2. Problem: (CQ38965) iSCSI connection timeout on bnx2x.

Cause: During CFC Delete RAMROD completion handling, the wrong (older)
iSCSI connection ID can sometimes be retrieved using the
harware CID. The CID in the mapping table was not cleared
after the CID was freed.

Fix: Adding clearing of the CID in the data structure after a CID
is freed.

Impact: bnx2x iSCSI.

Enhancements
------------
1. Change: (CQ38744) Reduced R2TQ memory usage to match new firmware
interface (firmware 4.8.9). This reduces the amount of
kernel memory substantially for each iSCSI connection on
bnx2x.

Impact: bnx2x iSCSI.

bnx2 v1.8.2b, cnic v1.7.3 (Dec 17, 2008)
========================================
Enhancements
------------
1. Change: Added iSCSI configuration check on 57711E devices before
allowing iSCSI connections.

Impact: bnx2x iSCSI.

bnx2 v1.8.2b, cnic v1.7.2 (Nov 25, 2008)
========================================
Fixes
-----
1. Problem: bnx2x iSCSI does not work on functions 2 or above.

Cause: This was caused by multiple problems:
a) Status block ID specified by bnx2x was wrong.
b) MSI-X vector assigned to CNIC was wrong.
c) New method to ack. status block using HC register was not
implemented.
d) Status block ID in CSTORM status block is always 0, and
as a result, the status block ID used to ack. the status
block was wrong.

All these problems only affect functions 2 and above.

Change: All problems fixed in bnx2x and cnic.

Impact: bnx2x iSCSI.

bnx2 v1.8.2b, cnic v1.7.1 (Nov 15, 2008)
========================================
Enhancements
------------
1. Change: Added CNIC support for Multi function bnx2x iSCSI.

Impact: bnx2x iSCSI.

bnx2 v1.8.2b, cnic v1.6.2 (Nov 12, 2008)
========================================
Enhancements
------------
1. Change: Updated to latest 4.6.13 5709 firmware to fix context corruption
with flow control enabled.

Impact: 5709.

2. Change: Added support for 5716S PCI ID.

Impact: None.

Fixes
-----
1. Problem: (CQ35904) Netdump does not work.

Cause: Problem introduced by MSI-X multiqueue. IRQ handlers were
changed to take bnx2_napi parameter instead of netdev parameter.

Change: Fixed by passing proper parameter to IRQ handler from netpoll.
All IRQ handlers are called when using multiple MSI-X vectors.

Impact: 5709 netpoll.

bnx2 v1.8.1f, cnic v1.6.1 (Nov 5, 2008)
========================================
Fixes
-----
1. Problem: All TSO packets corrupted on 5706/5708.

Cause: Firmware bug zeroing the wrong field in IP header.

Change: Updated to latest 4.6.11 5706/5708 firmware and 4.6.12 5709
Firmware.

Impact: 5706/5708/5709.

2. Problem: bnx2x chip asserts when trying to make iSCSI connection
to an unknown IP address.

Cause: When connection fails, the driver sends a command to an
unitialized CID.

Change: Added logic to only send deletion commands to initialized
CIDs.

Impact: bnx2x iSCSI.

Enhancements
------------
1. Change: Added support for one single VLAN to a bnx2x iSCSI interface.

Impact: bnx2x iSCSI.

bnx2 v1.8.1e, cnic v1.6.0 (Oct 27, 2008)
========================================
1. Change: Updated to latest 5709 firmware to fix iSCSI data integrity
problem.

Impact: 5709.

bnx2 v1.8.1d, cnic v1.6.0 (Oct 23, 2008)
========================================
Enhancements
------------
1. Change: Updated to latest bnx2 firmware to fix iSCSI data integrity
problem.

Impact: 5706/5708/5709.

2. Change: Updated to the latest bnx2x HSI files.

Impact: bnx2x iSCSI.

bnx2 v1.8.1c, cnic v1.5.9 (Oct 13, 2008)
========================================
Fixes
-----
1. Problem: (CQ37905) Unable to compile on SLES10 SP2.

Cause: DIV_ROUND_UP macro not defined in this kernel.

Change: Added it for compatibility.

Impact: None.

Enhancements
------------
1. Change: Updated to latest 5709 firmware that fixes an NCSI problem.

Impact: 5709.

2. Change: Handle TCP reset in the middle of TCP close more appropriately.

Impact: iSCSI.

3. Change: Handle iSCSI license checking in the same way as 5708/5709.

Impact: iSCSI on bnx2x.

bnx2 v1.8.1b, cnic v1.5.8 (Oct 13, 2008)
========================================
Fixes
-----
1. Problem: bnx2x iSCSI CIDs may be allocated outside the range of allocated
host memory.

Cause: CID range bigger than the amount of allocated host context
memory.

Change: Changed to match the CID range with memory range.

Impact: bnx2x iSCSI.

Enhancements
------------
1. Change: Sync'ed with the latest upstream driver bnx2 1.8.1.

Impact: None.

2. Change: Implemented iSCSI connection license enforcement for bnx2x
devices.

Impact: bnx2x iSCSI.

bnx2 v1.8.0j, cnic v1.5.7 (Oct 6, 2008)
========================================
Fixes
-----
1. Problem: (CQ37610) Chip hangs when changing MTU with active iSCSI
connections.

Cause: Both cnic and bnx2 drivers setting up the chip at the same
time.

Change: Added check so that the register_cnic function will fail
if the bnx2 driver is in reset.

Impact: iSCSI.

2. Problem: (CQ37762) Able to unload bnx2/bnx2x drivers while there are
active iSCSI connections.

Cause: CNIC driver does not have a reference count on the BNX2/BNX2X
drivers.

Change: This became a problem after the register_cnic function was
no longer exported. To solve the problem, the CNIC driver
will now get an explicit reference during register_cnic.

Impact: iSCSI.

3. Problem: (CQ37429) MMIO access while the chip is in D3hot state.

Cause: The driver does not check if_running state consistently during
ethtool operations.

Change: Added proper checks to all ethtool and multicast change
functions.

Impact: ethtool operations and multicast operations.

Enhancements
------------
1. Change: Simplified ipv4 TSO logic in the driver. This was made
possible with newer 5708 firmware.

Impact: 5708 TSO and other traffic.

2. Change: ethtool -p now blinks forever. This is the standard behavior
in most other net drivers.

Impact: ethtool -p.

bnx2 v1.8.0i, cnic v1.5.5 (Sep 30, 2008)
========================================
Fixes
-----
1. Problem: (CQ36787) iSCSI login/logout commands fail on 5709 after a
while.

Cause: Not handling the KWQ completion properly on 5709 in INTA/MSI
mode.

Change: Changed to handle KWQ completions by checking the
cmd_consumer_index instead of the rx_quick_index15.

Impact: 5709 ISCSI in INTA/MSI mode.

2. Problem: (CQ37497) CNIC driver does not compile on powerpc.

Cause: csum_ipv6_magic() not defined.

Change: Added #include

Impact: None.

v1.8.0g (Sep 24, 2008)
========================
Fixes
-----
1. Problem: (CQ37511) System locks up when loading cnic driver on 2.6.16
kernel.

Cause: symbol_put_addr() in 2.6.16 tries to acquire the same lock twice.

Change: Workaround by using __symbol_put() which does not have the same
problem.

Impact: None.

v1.8.0f (Sep 23, 2008)
========================
Fixes
-----
1. Problem: (CQ37405) Kernel panic when performing ifup/ifdown with iSCSI
connections on bnx2x devices.

Cause: Sending searcher delete to bnx2x devices when connection was
not established (due to Spanning Tree or other reasons).

Change: Check PG offload state before sending searcher delete.

Impact: iSCSI on bnx2x.

v1.8.0e (Sep 22, 2008)
========================
Enhancement
-----------
1. Change: Updated to latest driver firmware 4.6.6 for 5709.

Impact: 5709.

2. Change: Updated cnic so that it will not crash even if using older
bnx2/bnx2x drivers without CNIC support. The net driver
can also be loaded after cnic and it will still work without
crashing.

Impact: iSCSI.

3. Change: (CQ 37381) Updated driver to check Vaux PRESET before allowing
WoL. This is needed to support 5709 quad-port boards.

Impact: WoL on all devices.

v1.8.0d (Sep 15, 2008)
========================
Enhancements
------------
1. Change: Updated CNIC iSCSI setup for bnx2x devices.

Impact: iSCSI on bnx2x devices.

v1.8.0c (Aug 25, 2008)
========================
Fixes
-----
1. Problem: Does not compile on older kernels.

Cause: "__maybe_unused" undefined on older kernels. "num_online_cpus()"
undefined on 2.4 kernels.

Change: Added compatibility code to workaround.

Impact: None.

v1.8.0b (Aug 25, 2008)
========================
Enhancement
-----------
1. Change: Updated to latest driver firmware 4.6.2 for 5709.

Impact: 5709.

v1.7.9c (Aug 5, 2008)
========================
Fixes
-----
1. Problem: bnx2 does not compile on older kernels.

Cause: is missing on 2.6.19 and older kernels.

Change: Added compatibility code to check for kernel version before
including the file.

Impact: none.

v1.7.9b (Aug 5, 2008)
========================
Enhancements
------------
1. Change: Added multi-tx ring for 5709. This fetaure is available on
2.6.27 kernel when using MSI-X.

Impact: 5709

2. Change: Added support for 57710 iSCSI in the CNIC driver.

Impact: iSCSI.

v1.7.7c (July 14, 2008)
========================
Fixes
-----
1. Problem: Source RPM fails to build.

Cause: New file missing in tarball.

Change: Added missing file.

Impact: None.

v1.7.7b (July 9, 2008)
========================
Enhancements
------------
1. Change: Added probe function so that the CNIC driver can get the
pci_device pointer earlier before registration.

Impact: iSCSI.

2. Change: Added support for 5716.

Impact: None.

v1.7.6c (June 6, 2008)
========================
Enhancements
------------
1. Change: Added multi-ring RX support on 5709 using MSI-X. This feature
is only available on 2.6.24 and newer kernels running on SMP
machines.

Impact: 5709.

2. Change: Added secondary unicast address support. We now support up
to 5 unicast addresses. This feature is only available on
2.6.23 and newer kernels.

Impact: All chips.

v1.7.6b.1 (Aug 14, 2008)
========================
Fixes
-----
1. Problem: (CQ36808) VLAN tagged packets received by host stack without
the VLAN tag.

Cause: If no VLANs are set up using vconfig, and if the driver
configures the chip to strip the VLAN tag, the problem can
happen. With IPMI or UMP enabled, the driver is likely to
configure the chip to strip the VLAN tag.

Change: Modified the driver to re-insert the VLAN tag when necessary.
I.e. when IPMI/UMP is enabled and vconfig has not setup any
VLANs.

Impact: All chips receiving VLAN traffic.

v1.7.6b (May 29, 2008)
========================
Fixes
-----
1. Problem: IPv4 TSO generates bad packet when the TSO packet size
is 1-MSS.

Cause: Probably firmware does not expect this boundary condition.

Change: Detect this 1-MSS condition in driver and skip the TSO logic.
1-MSS TSO packet will be treated like a regular TX checksum
offload packet.

Impact: TSO on all chips.

2. Problem: Cannot disable VLAN stripping even when management firmware
is disabled.

Cause: The new logic to check firmware VLAN stripping capability
was buggy.

Change: Fixed the code so that VLAN stripping can always be disabled
if management firmware is disabled.

Impact: VLAN/management firmware.

v1.7.5d (May 13, 2008)
========================
Enhancements
------------
1. Change: Incorporated latest firmware 4.4.18. Bug fix is in
RV2P.

Impact: All chips.

v1.7.5c (May 7, 2008)
========================
Enhancements
------------
1. Change: Incorporated latest firmware 4.4.17. Bug fix is in
RV2P.

Impact: All chips.

v1.7.5b (May 5, 2008)
========================
Fixes
-----
1. Problem: (CQ35080) Hard lock when running ethtool -s on the device
that is in the down state.

Cause: I/O to the device to set link speed in D3-hot state can cause
lockup because the chip does not respond to I/O.

Change: ethtool -s will just store the new settings without configuring
the new speed. When the device is later brought up, the new
speed will be set as part of chip init.

Impact: All chips.

2. Problem: (CQ35075 CQ35042) Various compile errors on SuSE SLES 9 and SLES
10 distro kernels.

Cause: ip_hdr() and __le32/__le32 backported to the distro kernels.

Change: Adjusted compatibility defines.

Impact: None.

Enhancements
------------
1. Change: Incorporated latest 5709 firmware 4.4.16. Timer context
scanning is reduced with this firmware to 500us. With this,
the temporary enhancement in 1.7.4c #2 has been removed.

Impact: 5709 iSCSI.

v1.7.4e (April 26, 2008)
========================
Fixes
-----
1. Problem: (CQ34841) 5709 does not link up on some remote PHY systems.

Cause: No initial link interrupt.

Change: Added code to poll for link when remote PHY is present.

Impact: Remote PHY systems.

2. Problem: (CQ34767) Kernel panic on 5709 when using jumbo frames
with NCSI traffic.

Cause: RV2P bug causing RX packets to overwrite kernel memory.

Change: Updated to latest RV2P code for 5709 and 5708.

Impact: 5706/5708/5709.

v1.7.4d (April 17, 2008)
========================
Fixes
-----
1. Problem: IPv6 iSCSI does not work.

Cause: Added code in the last version 1.7.3c to check for CONFIG_IPV6
before enabling the IPv6 CNIC support. This failed to check
for CONFIG_IPV6_MODULE if IPv6 is configured as module in the
kernel configuration.

Change: Changed the checking to CONFIG_IPV6 or CONFIG_IPV6_MODULE.

Impact: None.

v1.7.4c (April 16, 2008)
========================
Fixes
-----
1. Problem: (CQ34814, CQ33984) Driver does not compile on 2.4 kernels.

Cause: __le32 and __be32 not defined in 2.4 kernels.

Change: Defined these as u32 on 2.4 kernels.

Impact: 2.4 kernels.

Enhancements
------------
1. Change: Incorporated latest 5709 4.4.12 firmware to fix various iSCSI
problems.

Impact: 5709.

2. Change: Slowed down the timer block reload time. It was noticed that
after the CNIC driver was unloaded, the timer context memory
was reloaded in a tight loop by the chip. This issue needs
to be properly addressed in the firmware at a future date.

Impact: iSCSI.

v1.7.4b (April 11, 2008)
=======================
Enhancements
------------
1. Change: Incorporated latest 5709 4.4.11 firmware to fix various iSCSI
problems.

Impact: 5709.

v1.7.3k (April 9, 2008)
=======================
Enhancements
------------
1. Change: Incorporated latest 5709 4.4.10 firmware to fix various iSCSI
problems. CID ranges are now read directly from shared memory.

Impact: 5709.

v1.7.3j (April 7, 2008)
=======================
Fixes
-----
1. Problem: (CQ33967) Ethtool register test fails.

Cause: Register 0x1004 context status register should not be tested.

Change: Removed 0x1004 from register test.

Impact: None.

Enhancements
------------
1. Change: Incorporated latest 5709 4.4.9 firmware to fix various iSCSI
problems.

Impact: 5709.

v1.7.3i (April 4, 2008)
=======================
Fixes
-----
1. Problem: (CQ33948) iSCSI over IPv6 does not work on SLES10.

Cause: The CNIC driver does not handle IPv6 on older kernels without
NETEVENTS support.

Change: Modified the logic to support older kernels.

Impact: All iSCSI connections using IPv4 or IPv6.

2. Problem: (CQ34315) Scanning iSCSI disks during max sessions test causes
connection problems.

Cause: 5709 context memeory allocated by CNIC driver does not match
the iSCSI and PG CID range used by the firmware.

Change: Changed to the matching CID range.

Impact: 5709 iSCSI.

v1.7.3h (March 28, 2008)
=======================
Fixes
-----
1. Problem: (CQ33984, CQ34210, CQ34310, CQ34597) Various compiler warnings
and errors on RHEL, SuSE, and 2.4 kernels.

Cause: New features not compatible with older kernels, or older
vendor kernels backported with newer features.

Change: Fine-tuned compatibility compiler directives.

Impact: All kernels.

v1.7.3g (March 10, 2008)
=======================
Enhancements
------------
1. Change: Updated to latest 5709 firmware version 4.4.7.

Impact: 5709.

v1.7.3f (March 10, 2008)
=======================
Fixes
-----
1. Problem: CNIC takes a long time to resolve ARP, causing iSCSI to fail.

Cause: NETEVENT_NEIGH_UPDATE event notifier sometimes takes a long time
to be called.

Change: This is under investigation. For now, the workaround is to
use the existing neighbour entry if it is in NUD_VALID state.
Previously, we would only use it if it was in NUD_CONNECTED
state.

Impact: iSCSI neighbour resolution.

2. Problem: iSCSI sometimes fails to initialize.

Cause: The KWQ is in full condition and prevents any KWQE to be sent
to the firmware. This is caused by the KWQ consumer index in
the status block not initializing to 0.

Change: Added workaround to skip the KWQ full condition check when
sending the first KWQE. This should be properly fixed in
firmware.

Impact: None.

v1.7.3d (February 15, 2008)
============================
Fixes
-----
1. Problem: System hangs with iSCSI traffic.

Cause: Infinite loop in NAPI poll.

Change: Fixed the problem of not comparing the CNIC tag properly when
determining whether there is more work in NAPI poll.

Impact: None.

2. Problem: iSCSI does not work on 5709

Cause: Not initializing 5709 properly for iSCSI. The chip_id field was
not propagated to the CNIC driver.

Change: Fixed the chip_id field.

Impact: None.

v1.7.3c (February 09, 2008)
============================
Enhancements
------------
1. Change: Updated 5708 and 5709 firmware to version 4.4.2.

Impact: All devices.

2. Change: Updated RV2P firmware to the latest. This may fix the jumbo
frame issue.

Impact: All devices, especially jumbo frames on 5709 Bx.

3. Change: Modified CNIC interface in preparation for 57710 devices.

Impact: iSCSI.

v1.7.2f (February 04, 2008)
============================
Fixes
-----
1. Problem: Temporary workaround for one prototype 5709S mezz. card not
working.

Cause: The driver was looking at the wrong shared memory location to
identify the card.

Change: Fixed the code to check the correct BNX2_SHARED_HW_CFG_CONFIG
location.

Impact: 5709S.

v1.7.2e (January 31, 2008)
============================
Fixes
-----
1. Problem: (CQ33704) CNIC driver fails MSI-X mode on 5709.

Cause: When implementing the fix, the wrong constant was used
for the CNIC MSI-X vector.

Change: Corrected to use the correct constant BNX2_CNIC_VEC.

Impact: None.

2. Problem: iSCSI outgoing packets over IPv6 are bigger than 1518 bytes.

Cause: MSS calculation was based on IPv4 and did not accout for the
IPv6 header size.

Change: Adjusted MSS calculation for IPv6.

Impact: None.

v1.7.2c (January 30, 2008)
============================
Fixes
-----
1. Problem: CNIC driver does not work in MSI-X mode on 5709.

Cause: This is a regression caused by moving the CNIC MSI-X
vector from 8 to 2. The context memory did not get
updated with the new vector.

Change: Changed the definition. All bits that depend on the
MSI-X vector will now have the proper definitions automatically.

Impact: None.

v1.7.2b (January 30, 2008)
============================
Enhancements
------------
1. Change: Updated 5709 firmware to 4.4.1.

Impact: 5709.

2. Change: Added temporary workaround for one prototype 5709S mezz. card.
The workaround will be removed once newer cards are available.

Impact: 5709S.

v1.7.1e (January 14, 2008)
============================
Enhancements
------------
1. Change: Updated 5709 firmware to 4.1.1 for IPv6 iSCSI support.

Impact: 5709.

2. Change: Updated 5708 RXP firmware to 4.1.1.

Impact: 5706/5708.

3. Change: Updated RV2P firmware for 5709.

Impact: 5709.

4. Change: Added IPv6 support to CNIC driver.

Impact: New BNX2I driver must be used with this new CNIC driver.

v1.7.1d.3 (February 7, 2008)
============================
Fixes
-----
1. Problem: 5706S continues to not link down occasionally on some blade
systems.

Cause: In some cases, even turning off the tx current does not
cause the link to go down.

Change: Link transition can be triggered based on the SYNC_FAILED bit
in the AN_DEBUG register when all else fails.

Impact: 5706S.

v1.7.1d.1 (February 1, 2008)
============================
Fixes
-----
1. Problem: 5706S still not linking down occasionally on some blade
systems when the switch blade is disconnected.

Cause: Occasionally, all the bits that we check will falsely
indicate link up and trigger the parallel detect logic on
this blade platform. Once in parallel detect mode with
autoneg disabled, the driver will never detect link down.

Change: Disabled parallel detect on this platform by checking
PCI sub IDs to identify the device.

Impact: Parallel detect not supported on this vendor device.

v1.7.1d (January 25, 2008)
============================
Fixes
-----
1. Problem: 5706S still not linking down on some blade systems when the
switch blade is disconnected.

Cause: This is the same problem that was fixed in 1.7.0b. After
switch module is removed, the SYNC_FAILED bit sometimes
toggles low, and this causes the parallel detect logic in the
driver to trigger and disable autoneg. Disabling autoneg
causes false link to come up immediately.

Change: It seems that the RUDI_INVALID bit can be used to prevent the
above from happening. Modified parallel detect code to
additionally check the RUDI_INVALID bit and trigger only when
the bit is cleared.

Impact: Parallel detect logic in 5706S.

v1.7.1c (December 27, 2007)
============================
Fixes
-----
1. Problem: Driver crashes when adding VLAN and bonding.

Cause: Bonding calls driver's VLAN function in interrupt context with lock
held. We recently added a VLAN feature in 1.6.8b which requires
chip reset when VLANs are added or removed. The reset will call
vmalloc/vfree which must not be called in interrupt context.

Change: Reverted the VLAN feature for now. Will workaround it in the
future.

Impact: 5709 only. This new VLAN feature is no longer available.

v1.7.1b (December 24, 2007)
============================
Fixes
-----
1. Problem: Driver crashes when using jumbo frames on 5709 A1.

Cause: RV2P firmware problem.

Change: Disabled jumbo page ring on 5709 Ax chips.

Impact: Jumbo receive page rings not supported on 5709 Ax.

2. Problem: CNIC driver prints "Failed waiting for ref count to go to zero"
when unloading the driver. This is a minor cosmetic issue.

Cause: Minor bug in driver comparing ref_count to 1 instead of zero
during exit.

Change: Fixed the code to check for ref_count == 0.

Impact: None.

v1.7.0b (December 12, 2007)
============================
Fixes
-----
1. Problem: (CQ33032) CPU utilization increases dramatically when TSO
is enabled.

Cause: Driver is spending a lot of unnecessary time in TX handling
code when TSO is enabled. This regression was introduced when
the TX handling code was changed to match the RX handling code.
The RX handling code was changed to fix a packet rot problem.
When TSO is enabled, the tx index can stop at non-packet
boundaries and the code will keep waiting until it gets to the
next packet boundary.

Change: Fixed it to handle this condition properly.

Impact: None.

2. Problem: 5706S does not link down in some blade systems.

Cause: Hardware problem.

Change: Added workaround logic to check periodically and force a
link down when the PHY reports SYNC status failed. This
only works when autoneg is enabled.

Impact: 5706S.

v1.6.8e (December 10, 2007)
============================
Fixes
-----
1. Problem: When using jumbo MTU with large RX ring sizes, system will
crash or the driver won't load.

Cause: Bug in driver where the page descriptor array was declared
too small.

Change: Fixed the array size.

Impact: None.

2. Problem: CNIC driver won't compile on kernels without CONFIG_PCI_MSI.

Cause: Some code needs to be conditionally compiled only when
CONFIG_PCI_MSI is set.

Change: Added #ifdef CONFIG_PCI_MSI where necessary.

Impact: None.

3. Change: Disabled iSCSI on 5709 until next release.

Impact: None.

v1.6.8d (December 07, 2007)
============================
Change: Reverted the 5706S workaround made in 1.6.8c because it was
unreliable.

Impact: None.

v1.6.8c (December 07, 2007)
============================
Fixes
-----
1. Problem: (CQ32794) Kernel panic (skb_over_panic) with jumbo frames.

Cause: RV2P firmware incorrectly placed jumbo data into SKB.

Change: New RV2P firmware.

Impact: Jumbo frames on all hardware.

2. Problem: (CQ32817) ethtool loopback test fails.
3. Problem: (CQ32842) Chariot test fails.

Cause: RX buffer size too small to contain MTU-sized frame.
This was introduced by the new Jumbo RX logic.

Change: Fixed RX buffer size logic.

Impact: Traffic on all hardware.

4. Problem: (CQ32862) Fails to compile on RH9u9.

Cause: Kernel API skb_fill_page_desc() backported to RH kernel
causing duplicate definition.

Change: Adjusted compatibility code.

Impact: None.

5. Problem: (CQ32866) ISCSI driver fails to compile with 1.6.8b.

Cause: print_mac() multiply defined when bnx2.h is included
in the bnx2i driver.

Change: Changed print_mac() to static inline.

Impact: None.

6. Problem: 5706S does not link down in some blade systems.

Cause: Hardware problem.

Change: Added workaround logic to check periodically.

Impact: 5706S.

Enhancements
------------
1. Change: Added flow control logic on 5709.

Impact: 5709.

2. Change: Updated all firmware to 4.0.5.

Impact: All hardware.

v1.6.8b (November 28, 2007)
============================
Enhancements
------------
1. Change: Added MSIX support for 5709 B0.

Impact: 5709 B0.

2. Change: Added multi-page buffer support for Receive Jumbo frames.

Impact: All chips. This feature is experimental at this point.

3. Change: Allow VLAN tags in receive packets when management firmware
is enabled.

Impact: 5709 only. This feature is experimental and requires new
boot code and UMP/IPMI code.

4. Change: Updated firmware to 4.0.3.

Impact: All chips.

v1.6.7b (October 16, 2007)
============================
Fixes
-----
1. Problem: (CQ31861) Remote copper PHY does not link up if WoL is enabled.

Cause: bnx2_set_power_state() assumes that only copper devices support
WoL and proceeds to configure the copper PHY to 10/100 Mbps.
This assumption is no longer valid after Serdes WoL support
was added in 1.6.3c.

Change: Fixed the code to take check for Serdes and copper when setting
up the PHY for WoL.

Impact: WoL.

v1.6.6b (October 10, 2007)
============================
1. Change: Update 5708 firmware to 3.7.19.

v1.6.5k (October 10, 2007)

v1.6.5c (September 26, 2007)
============================
Enhancements
------------
1. Change: Update 5708 firmware to 3.7.14.

v1.6.5b (September 25, 2007)
============================
Fixes
-----
1. Problem: (CQ30086) 5709 A1 does not link up when connected to
some Broadcom devices.

Cause: Early DAC wakeup workaround needed for 5709 A1.

Change: Added workaround.

Impact: None.

Enhancements
------------
1. Change: Added CNIC support for iSCSI.

Impact: Only enabled on 2.6.16 and newer kernels.

v1.6.3c (July 23, 2007)
=======================
Fixes
-----
1. Problem: (CQ30591) ethtool -t fails on remote PHY systems.

Cause: Link test and loopback test were not modified to support
remote PHY.

Change: Added remote PHY support to link test and changed the code
to skip PHY loopback on remote PHY since it's not supported.

Impact: None.

2. Problem: (CQ30625) ethtool speed settings are lost after ifdown.

Cause: The remote PHY settings stored in firmware is not the same
as the driver's last setting.

Change: Modified the code to keep the driver's setting unless there's
is change in the remote PHY media.

Impact: ethtool -s on remote PHY systems.

Enhancements
------------
1. Change: Change ethtool's wol setting to NVRAM's default and
add support for Serdes WoL if NVRAM supports it.

Impact: ethtool wol's default setting.

v1.6.3b (July 13, 2007)
=======================
1. Problem: Problems reading and writing flash on 5709.

Cause: Hardware changes in 5709.

Change: Rearranged current flash code to properly support 5709.

Impact: Changes will impact flash operations on 5706/5708/5709 devices.

2. Problem: (CQ30516) Management firmware version string disappears
on 2nd modprobe of the driver.

Cause: The 2nd modprobe will program the device back to D0 from D3hot.
This causes a reset and it will take some time before the
management firmware information will be available.

Change: Added a proper wait loop to wait for the firmware information
to be deposited in shared memory.

Impact: None.

v1.6.2f (July 3, 2007)
=======================
1. Problem: The fix for CQ29488 in the previous version is problematic
and needs to be reverted.

Cause: Adding the netif_carrier_off() call before register_netdev()
in bnx2_init_one() can cause problems if register_netdev()
fails. netif_carrier_off() can queue a link watch event
that can run later. If register_netdev() fails, the netdev
structure will be freed and the link watch event may panic
when it is scheduled to run.

Change: Moving the netif_carrier_off() to after register_netdev()
also will not work as it can cause race conditions with
the interrupt handler. So the best thing to do is to
revert the earlier fix and not address the CQ29488 issue.

Impact: CQ29488 is not fixed.

v1.6.2e (July 3, 2007)
=======================
Fixes:
------
1. Problem: (CQ29528) Link does not come up using remote PHY (continued).

Cause: ifup script may be using mii-tool to obtain link status,
and interfering with remote PHY firmware.

Change: Block mii-tool ioctl access when remote PHY firmware is present.

Impact: None.

2. Problem: (CQ29488) Driver reports link up in ethtool before the interface
is brought up.

Cause: The netdevice structure's initial link setting is up and that
gets reported directly by ethtool.

Change: Added netif_carrier_off() call in bnx2_init_one().

Impact: None.

v1.6.2d (June 22, 2007)
=======================
Fixes:
------
1. Problem: (CQ29528) Link does not come up using remote PHY.

Cause: The fix in 1.6.2b still has a problem. The copper or Serdes
default link setting does not follow the correct port when
the port is changed during chip reset.

Change: Fix the code to always refresh the port and link setting
during chip reset.

Impact: None.

2. Problem: (CQ30181) Cannot compile on 2.4 kernels.

Cause: USEC_TO_SEC constant is not defined on older kernels.

Change: Added conditional #define for this constant on older kernels.

Impact: None.

Enhancements:
-------------
1. Change: Update 5709 firmware to 3.7.1.

Impact: 5709 devices.

v1.6.2b (June 21, 2007)
=======================
Enhancements:
-------------
1. Change: Added management firmware version to ethtool -i.

Impact: None.

Fixes:
------
1. Problem: (CQ29528) Link does not come up using remote PHY.

Cause: The driver is using the wrong port when setting up the remote
PHY link.

Change: Fixed bug to always use the correct requested port or
default port when setting remote PHY link.

Impact: None.

2. Problem: (CQ30028) Advertised Autoneg not set in ethtool.

Cause: Remote PHY code is not setting the flag which is for
information only.

Change: Added code the set the flag for consistency.

Impact: None.

v1.6.1c (May 22, 2007)
=====================
Enhancements:
-------------
1. Change: (CQ28907) Added support for setting copper and fibre speeds.

Impact: Only available on Remote PHY systems.

v1.6.1b (May 7, 2007)
=====================
Fixes:
------
1. Problem: (CQ29301) Setting invalid speed setting causes driver to
crash.

Cause: Lock taken without unlock when exiting iwith error the
procedure to set speed.

Change: Fixed the code with proper unlock.

Impact: None.

v1.6.0b (April 30, 2007)
========================
Enhancements:
-------------
1. Change: Improved handshake with remote PHY firmware.

Impact: None.

v1.5.10c (May 4 , 2007)
=======================
Fixes:
------
1. Problem: Extremely low TSO performance when destination has a
smaller MSS than the source.

Cause: Packets smaller than MTU are not processed as TSO packets.

Change: Removed the SKB length check when doing TSO.

Impact: None.

v1.5.10b (May 1, 2007)
=========================
Enhancements:
-------------
1. Change: Removed Remote PHY until next release.

Impact: No Remote PHY support.

2. Change: Added check for 2.5G capability before enabling 2.5G on
5709S.

Impact: None.

Fixes:
------
1. Problem: (CQ28438) NETDEV WATCHDOG after OS boot.

Cause: The mailbox queue is halted after the OS reads config.
register 0x94.

Change: Set MQ_CONFIG_HALT_DIS in register MQ_CONFIG on 5709 A0 and
A1.

Impact: None.

v1.5.9b (April 20, 2007)
=======================
Enhancements:
-------------
1. Change: Enhanced remote PHY support for 5708S.

Impact: None.

Fixes:
------
1. Problem: (CQ29056) Driver does not compile on SLES 10 SP1 kernel.

Cause: Backported netif_tx_lock() causes compatibility problem.

Change: Adjuested compatibility #ifdef.

Impact: None.

2. Problem: (CQ28880) Driver fails register test after running traffic.

Cause: A reserved register 0x500c was mistakenly included in the test.

Change: Removed this register from the test.

Impact: None.

v1.5.8b (March 13, 2007)
=======================
Enhancements:
-------------
1. Change: Added remote PHY support for 5708S.

Impact: None.

v1.5.7b (March 2, 2007)
=======================
Enhancements:
-------------
1. Change: Added IPV6 TSO for 5709.

Impact: None.

2. Change: Added 2.5G parallel detection for 5709s.

Impact: None.

v1.5.6b (February 28, 2007)
===========================
Enhancements:
-------------
1. Change: Added Serdes support for 5709.

Impact: None.

Fixes:
------
1. Problem: (CQ28433) Driver does not compile on some early 2.6 and
2.4 kernels.

Cause: Kernel compatibility issue.

Change: Added some missing #ifdef CONFIG_PCI_MSI.

Impact: None.

2. Problem: (CQ28527) System hangs when running bonding scripts on 5709.

Cause: Bonding driver reads MDIO registers after the device is in
D3hot state.

Change: Added check to disallow MDIO access after the device is down.

Impact: None.

v1.5.5b (January 31, 2007)
===========================
Fixes:
------
1. Problem: (CQ28252) Driver reports the same MAC address for both
ports of 5709.

Cause: The driver was obtaining the MAC address from the same
shared memory area for both ports.

Change: Updated driver to read from the deicated shared memory
area for each port.

Impact: None.

2. Problem: (CQ28226) 5709C does not link up when connected to Dell
5324 and some other switches.

Cause: PHY's Early DAC Wakeup Enable bit's strapped value is set.

Change: Disable Early DAC Wakeup enable on 5709 A0 after PHY reset.

Impact: None.

v1.5.4b (January 8, 2006)
===========================
Fixes:
------
1. Problem: 5709 copper device detected as serdes.

Cause: Media detection code not complete.

Change: Added complete media detection code.

Impact: None.

Enhancement:
------------
1. Change: Add IPv6 checksum support.

Impact: None.

v1.5.2b (December 22, 2006)
===========================
Merged in all latest changes.

v1.5.1c (November 30, 2006)
===========================
Enhancement:
------------
1. Change: Remove 5709 FPGA code.

Impact: None.

v1.5.1b (November 15, 2006)
===========================
Enhancement:
------------
1. Change: Added support for 5709.

Impact: None.

v1.4.52c (March 07, 2007)
=========================
Enhancement:
------------
1. Change: Increase maximum receive ring size to 4080.
The default is kept the same at 255.

Impact: None.

v1.4.51b (December 21, 2006)
============================
Fixes:
------
1. Problem: (CQ27802) Cannot enable flow control in some cases.

Cause: In some cases when flow control is forced to on, the
driver detects no changes in advertisement, and as a
result, will not re-autoneg. Without the link change,
flow control settings will not change.

Change: Added some code to setup flow control when no other
PHY settings are made. This will ensure that flow
control changes will take effect immediately.

Impact: None.

v1.4.50b (December 15, 2006)
============================
Fixes:
------
1. Problem: (CQ27424) Panic when writing to nvram.

Cause: Bug in driver when an alignment buffer is used

Change: Fixed the bug so that the alignment buffer is freed with the
correct pointer.

Impact: None.

v1.4.49b (December 13, 2006)
============================
Fixes:
------
1. Problem: (CQ27459) Driver reports link down when link is up.

Cause: Hotplug scripts can cause bnx2_open() to be called immediately
after bnx2_init_one() calls register_netdev(). The initial
link state set after register_netdev() may overwrite the actual
link state set by the link handler on SMP systems.

Change: Move all initial state setup code to before calling
register_netdev().

Impact : None.

v1.4.48b (December 08, 2006)
============================
Fixes:
------
1. Problem: (RHBZ 212055) Panic in bnx2_poll().

Cause: Bug in determining tx ring space when the tx ring is
completely full.

Change: Fixed the flawed logic in bnx2_tx_avail().

Impact: None.

2. Problem: (CQ27424) Buffer overflow when writing to nvram.

Cause: Bug in driver when the beginning NVRAM offset is
not 4-byte aligned.

Change: Fixed the bug to allocate enough buffer space.

Impact: None.

3. Problem: (CQ27543) Loopback failed if MAC address is changed.

Cause: Driver uses permanent MAC address for loopback which may
be different from a locally administered address.

Change: Fixed by alwaysing using the current MAC address in the
netdevice structure.

Impact: None.

v1.4.47b (November 02, 2006)
===========================
Fixes:
------
1. Problem: (CQ25922) 5708S does not pass PHY loopback test on
some blade servers.

Cause: It takes longer (about 100msec) to link up in some
backplane environments when the Serdes is set to PHY
loopback mode.

Change: Increase delay loop to up to 1 sec when waiting for
link up after PHY loopback. Previous wait time was
100usec.

Impact: None.

v1.4.46b (October 30, 2006)
===========================
Fixes:
------
1. Problem: (CQ25916) Device does not receive packets when configured
by the Xen bridge script and when IPMI is enabled.

Cause: Firmware does not forward packets to the host when the
device is in promiscuous mode in some cases.

Change: Firmware change and driver change to enable the
BNX2_RPM_SORT_USER0_PROM_VLAN bit when going into
promiscuous mode.

Impact: None.

v1.4.45b (October 19, 2006)
===========================
Enhancement:
------------
1. Change: Added software parallel detection on 5708S to link at
1000Mbps or 2500Mbps automatically if the link partner is
forced at 2500Mbps.

Impact: None.

2. Change: Added 2500Mbps forced speed setting. Setting it requires
a future version of ethtool or custom apps.

Impact: None.

3. Change: Port driver to compile on 2.6.19 kernel.

Impact: None.

Fixes:
------
1. Problem: Driver does not complile on 2.4 kernels.

Cause: TSO symbols not defined in 2.4 kernels.

Change: Added #ifdef for compatibility.

Impact: None.

2. Problem: MSI doesn't work on 5706 when the host bridge is AMD8132.

Cause: Compatibility issue.

Change: Added code to disable MSI when 5706 is on a systems with
AMD8132.

Impact: 5706 cannot use MSI on such systems.

v1.4.44b (August 10, 2006)
==========================
Fixes:
------
1. Problem: A rare tx race window exists in the tx path.

Cause: CPU re-ordering can cause the tx queue to be stopped
forever when the tx ring is full in a very rare
condition. See ChangeLog for more details.

Change: Fixed the race condition with memory barriers.
See ChangeLog for more details.

Impact: None.

Enhancement:
------------
1. Change: Increase default rx ring size to 255 to prevent
packet drops under heavy load.

Impact: Higher memory usage.

2. Change: Port driver to run on 2.6.18 kernel.

Impact: None.

v1.4.43b (June 26, 2006)
=======================
Enhancement:
------------
1. Change: (CQ25508) Use DRV_MSG_CODE_UNLOAD_LNK_DN message on
5708 B1 and older chips so that the link will turn
off after ifdown.

Impact: None.

v1.4.42b (June 2, 2006)
=======================
Fixes:
------
1. Problem: (CQ22585) WoL cannot be enabled on 5708 B2.

Cause: Hardware limitation in previous 5708 versions required
driver to always disable driver WoL on 5708.

Change: With the issue fixed in B2, the driver was changed to
allow 5708 B2 and above to support driver WoL.

Impact: None.

2. Problem: (CQ21779) Driver does not report dropped receive packets.

Cause: Packets dropped by firmware are reported in a scratch pad
location in memory separate from other counters.

Change: Added code to report this firmware counter.

Impact: None.

Enhancements:
-------------
1. Change: (CQ24690) Allow driver to be compiled for non-running kernels.

Impact: None.

v1.4.41b (May 17, 2006)
=======================
Fixes:
------
1. Problem: Driver writes wrong data to non-buffered flash.

Cause: Bug in driver causing the unchanged portion of the page
to be corrupted.

Change: Fixed bug.

Impact: None.

v1.4.40b (April 17, 2006)
=========================
Enhancements:
-------------
1. Change: Combine 2 small memory allocations into 1.

Impact: None.

2. Change: Separate tx consumer and producer entries into separate
cache lines for better performance.

Impact: None.

3. Change: Compress firmware data to reduce driver size.

Impact: Driver now requires zib_inflate library which should be
available on most vendor kernels.

v1.4.39b (Mar. 10, 2006)
=======================
Fixes:
------
1. Problem: (CQ23181) Driver loses track of link changes in some cases.

Cause: In some cases, the status block gets a link change indication
that contradicts with the MII link status. This is due to
transient link signals during link changes.

Change: Add coalesce_now at the end of link change interrupt to flush
out the transient behavior.

Impact: None.

2. Problem: 5708 only supports 40-bit DMA addresses.

Cause: Limitation of the built-in PCIE-to-PCIX bridge.

Change: Add workaround code to make sure all DMA addresses are
less than 40 bits.

Impact: Some minor impact on performance on some 64-bits systems.
There should be practically no performance impact on i386 and
x86_64 systems.

3. Problem: "Copyright" deprecated in RPM spec file.

Change: Changed to "License".

Impact: Should be none on the distributions that we support.

v1.4.38b (Feb. 10, 2006)
=======================
Fixes:
------
1. Problem: Setting rx ring size to 255 causes memory allocation errors.

Cause: Multiple bugs that do not handle the full ring properly.

Change: Fixed all bugs related to full ring handling and changed
maximum ring size from 4080 to 1020 after discussion with
Dave Miller.

Impact: Maximum rx ring size is now smaller.

2. Problem: Compile warnings and panic on IA64.

Cause: not included.

Change: Added include .

Impact: None.

v1.4.36b (Jan. 19, 2006)
=======================
Version number update.

v1.3.36 (Jan. 17, 2006)
=======================
Fixes:
------
1. Problem: (CQ22827) bnx2 does not compile on 2.6.6 and earlier
kernels.

Cause: Introduced bug while fixing CQ22666.

Change: Fix compatibility code.

Impact: None.

2. Problem: (CQ22823) bnx2 reports extra .5 at the end of firmware
version string.

Change: Skip the last digit in the firmware version string.

Impact: None.

3. Problem: (CQ22585) WoL still does not work on 5708.

Cause: New WoL mechanism introduced in 1.3.34 has a flaw.

Change: Removed the workaround code and disabled WoL support
on 5708. During shutdown and suspend, the driver will
shutdown the device and WoL will be setup by the
bootcode according to the nvram's out-of-box WoL
setting.

Impact: 5708 will not support driver-initiated (ethtool-intiated)
WoL.

v1.3.35 (Jan. 17, 2006)
=======================
Fixes:
------
1. Problem: (CQ22666) bnx2 driver does not compile on RHEL3 U7.

Cause: if_mii() back-ported to RHEL3 U7.

Change: Adjusted the compatibility code.

Impact: None.

2. Problem: (CQ22718) UMP connection is lost after enabling WoL.

Cause: FORCE LINK was mistakenly set during WoL setup.

Change: Do not set FORCE LINK.

Impact: None.

v1.3.34 (Jan. 13, 2006)
=======================
Fixes:
------
1. Problem: (CQ22585) WoL does not work on 5708.

Cause: Internal bridge not in proper PME state.

Change: Added new firmware message to allow bootcode to help set up
WoL.

Impact: None.

Enhancements:
-------------
1. Change: Added compile option to include crc32 function for RH2.4
boot kernels.

Impact: None.

2. Change: Updated TSO firmware to handle ECN.

Impact: None.

v1.3.33 (Dec. 12, 2005)
=======================
Enhancements:
-------------
1. Change: Increased firmware hand-shake timeout from 50 msec to
100 msec. Also changed the delay from busy-wait udelay
to non-busy-wait msleep.

Impact: None.

2. Change: Added code to read nvram size from shared memory if
available. Otherwise, the size will come from the
flash table which only gives the smallest size for
that type of flash.

Impact: None.

3. Change: Added workaround to issue 2 separate IOs for interrupt
acknowledgement. The workaround is only used for INTA
(non-MSI) interrupts.

Impact: Slightly higher overhead for INTA interrupts.

v1.3.32 (Dec. 01, 2005)
=======================
Enhancements:
-------------
1. Change: Added PHY loopback to the loopback selftest.

Impact: None.

2. Change: (CQ21810) Added ethtool -d register dump.

Impact: None.

3. Change: Reduce the number of registers tested in selftest to make
the driver smaller.

Impact: None.

4. Change: Increased maximum rx ring size to 4080.

Impact: None.

5. Change: Changed rx checksum logic for better reliability.

Impact: None.

6. Change: Added 5708 B1 workarounds.

Impact: None.

v1.3.31 (Nov. 18, 2005)
=======================
Fixes:
------
1. Problem: (CQTO2080) Cannot pass traffic during 2nd ifup if IPMI
is enabled.

Cause: A flaw in driver/firmware handshake.

Change: Changed driver/firmware handshake by doing WAIT0 first before
writing the first signature.

Impact: None.

2. Problem: (CQTO2056) VLAN-tagged IPMI traffic fails after driver is
loaded.

Cause: Driver configures the NIC to keep the VLAN tag by default,
causing VLAN-tagged IPMI traffic to fail.

Change: Changed driver to always strip VLAN tags if IPMI is enabled.

Impact: VLAN will always be stripped when IPMI is enabled. This may
affect some applications that rely on raw VLAN packets.

Enhancements:
-------------
1. Change: Sync'ed up with latest upstream bnx2.

v1.3.29 (Oct. 6, 2005)
=======================
Fixes:
------
1. Problem: (CQTO1929) Traffic stops when MTU is greater than 1500
with TSO enabled.

Cause: TSO firmware bug.

Change: Updated to latest firmware.

Impact: None.

v1.3.28 (Sep. 29, 2005)
=======================
Fixes:
------
1. Problem: (CQTO1875) Traffic stops when running Nettack with TSO
turned on.

Cause: TSO firmware bug.

Change: Updated to latest firmware.

Impact: None.

2. Problem: (CQTO1575) ethtool -S shows non-zero rx_error_bytes.

Cause: Hardware errata.

Change: Ignore this counter and always report zero.

Impact: None.

v1.3.27 (Sep. 21, 2005)
=======================
Enhancements:
-------------
1. Change: Enabled ethernet@wirespeed on copper devices.

Impact: None.

2. Change: Enabled customized pre-emphasis and other serdes control
settings on 5708S backplane devices. A special PHY
register will be programmed according to the NVRAM value.

Impact: None.

3. Change: Modified Makefile to check for the source symbolic link
in the kbuild environment.

Impact: None.

4. Change: Improved NAPI poll processing so that all events will be
processed before interrupts are re-enabled. This will
reduce the number of unnecessary interrupts.

Impact: None.

5. Change: Add support for ETHTOOL_GPERMADDR (from John Linville)

Impact: None.

Fixes:
------
1. Problem: Bug in irq handler causing extra register read.

Cause: Bug in bnx2_interrupt() reading BNX2_PCICFG_MISC_STATUS
register when it is not necessary.

Change: Fixed the logic bug and added prefetch of status block in
msi handler.

Impact: None.

v1.3.25 (Aug. 22, 2005)
=======================
Fixes:
------
1. Problem: Ethtool register and memory tests fail on 5708.

Cause: Some code was not merged properly many versions ago.

Change: Merged in properly code.

Impact: None.

Enhancements:
-------------
1. Change: Slow down flash clock speeds

Impact: None.

2. Change: Code re-sync'ed with upstream driver.

Impact: None.

v1.3.24 (Aug. 16, 2005)
=======================
Enhancements:
-------------
1. Change: Changed all spin_lock_irqsave locks to spin_lock_bh for
better overall system performance. All code requiring
spin_lock runs in BH or user context.

Impact: None.

2. Change: Removed atomic operations in the transmit fast path.
Code should run a bit faster as atomic operations can be
quite slow.

Impact: None.

v1.3.23 (Aug. 10, 2005)
=======================
Enhancements:
-------------
1. Change: Added reporting of link speed to firmware.

Impact: None.

2. Change: Added shared memory base look-up.

Impact: None.

3. Change: Possible sparse fixes (from Peter Hagervall)
- use C99 struct initializers
- make a few arrays and structs static
- remove a few uses of literal 0 as NULL pointer
- use convenience function instead of cast+dereference in
bnx2_ioctl()
- remove superfluous casts to u8 * in calls to readl/writel

Impact: None.

4. Change: Updated documentation with the crc32 library requirement and
other minor updates.

Impact: None.

v1.3.22 (July 25, 2005)
=======================
Enhancements:
-------------
1. Change: Added check for default link speed setting in shared memory.
This allows some blade servers that don't support autoneg to
default to forced speed to speed up link-up time.

Impact: None.

2. Change: Changed timer code to speed up the timer after serdes autoneg.
This speeds up the time for parallel detection when the link
partner does not autoneg. After autoneg or parallel detction
completes, timer goes back to normal 1 HZ interval. With the
new scheme, link should be detected up using parallel detection
in less than 0.7 seconds. Autoneg normally completes in 120
msec exchanging base pages and 3 next pages.

Impact: None.

v1.3.21 (July 21, 2005)
=======================
Enhancements:
-------------
1. Change: Updated firmware to properly handle TSO packets with ECN
bits set.

Impact: None.

2. Change: Updated to latest rxp firmware.

Impact: None.

3. Change: Added check for the 2.5G capability in shared memory.

Impact: None.

4. Change: Expanded nvram support for 5708.

Impact: None.

Fixes:
------
1. Problem: (CQTO1511) Downing a team of bnx2 adapters causes hang.

Cause: Deadlock when the second adapter's close routine calls
flush_scheduled_work() because the linkwatch_event
is scheduled on the work queue when the first adapter
is closed. The linkwatch_event will try to get the rtnl_lock
which is already held by the bnx2_close routine.

Change: Fixed by not calling flush_scheduled_work(). Instead,
use a flag to indicate work is pending and wait until
the flag is cleared.

Impact: None.

2. Problem: (CQTO1439) ethtool -S on 5708 causes oops.

Cause: A pointer is not initialized if the device is 5708.

Change: Added proper initialization.

Impact: None.

3. Problem: Some error counters are mis-reporting.

Cause: The workaround for the hw errata is not applied properly
on the chips with the errata.

Change: Added proper checks for the workaround.

Impact: None.

4. Problem: High BER on 5708 SerDes.

Cause: hardware errata.

Change: Added workaround for 5708 A0 and B0.

Impact: None.

v1.3.19 (May 27, 2005)
=======================
Enhancements:
-------------
1. Change: Merged 5708 code with the latest 1.1.19.

Impact: None.

Fixes:
------
1. Problem: (CQTO1260) 5708S does not link at 1000Mbps when forced. It
links at 2500Mbps when connected back-to-back with another
5708S.

Cause: 2.5G bit is still turned on.

Change: Fixed by turning off 2.5G when the speed is forced.

Impact: None.

v1.1.19 (May 26, 2005)
=======================
Enhancements:
-------------
1. Change: Made significant changes to merge into the kernel. Among
them, consolidate all source files into bnx2.[ch] and
bnx2_fw.h, change structure style register definitions
to offset based.

Impact: None.

Fixes:
------
1. Problem: Excessive stack usage.

Cause: Use of local variable array.

Change: Fix excessive stack usage in bnx2_alloc_bad_rbuf() by
replacing local variable array with kmalloc array. Also
changed function to return error code, and changed some
of the callers to check for the return code.

Impact: None.

2. Problem: Bug in receive checksum.

Cause: Software bug.

Change: Fix bug in rx checksum by indicating CHECKSUM_UNNECESSARY
only when the hw calculated checksum is 0xffff.

Impact: None.

3. Problem: Excessive busy loop.

Cause: Software bug.

Change: Replaced one excessive udelay of 15msec with msleep since
the calling context is always process.

Impact: None.

4. Problem: Need to call flush_scheduled_work() and bnx2_netif_stop().

Cause: Bug in bnx2_close().

Change: Fix bug in bnx2_close() by calling flush_scheduled_work()
since we are using a work queue in netdev watchdog. Also
added bnx2_netif_stop() call in bnx2_close().

Impact: None.

5. Problem: Some symbols do not have bnx2 prefix and are not static.

Change: Add bnx2_ prefix to some remaining names and mark some
remaining names static.

Impact: None.

v1.1.17 (Apr. 7, 2005)
=======================
Fixes:
------
1. Problem: Driver does not compile on 2.6.12 kernel.

Cause: pci_dev->slot_name has been deprecated.

Change: replaced with pci_name.

Impact: None. All kernels supported by bnx2 including 2.4.21-*EL have
pci_name defined.

v1.1.16 (Mar. 16, 2005)
=======================
Fixes:
------
1. Problem: (CQTO936 & 1004) Tx carrier and rx_byte_errors reported
during normal operations.

Cause: 5706 hardware errata on these 2 statistics counters.

Change: Modified driver to skip these 2 counters.

Impact: These 2 counters will always report 0 and not the true
statistics.

v1.3.15 (Mar. 11, 2005)
======================
Enhancements:
-------------
1. Change: Added SGMII 10/100/1000 Mbps and fiber mode 1000/2500 Mbps
support.

Impact: None.

v1.1.15 (Mar. 09, 2005)
=======================
Enhancements:
-------------
1. Change: Added code to program proper phy settings for jumbo
frames on copper and serdes devices.

Impact: None.

2. Change: Changed INTx ISR to handle a valid case where INTx
arrives before status block update.

Impact: None.

3. Change: Added a separate ISR for MSI to handle subtle differences
between INTx and MSI.

Impact: None.

v1.1.14 (Mar. 03, 2005)
======================
Fixes:
------
1. Problem: netdump does not work on latest RH3EL errata kernel.

Cause: #define RED_HAT_LINUX_KERNEL removed from kernel
include files, causing netdump poll function to
be compiled wrong for RH kernels.

Change: Changed Makefile to workaround the problem.

Impact: None.

v1.1.12 (Feb. 25, 2005)
======================
Fixes:
------
1. Problem: (CQTO1062) Driver allows ethtool to set illegal speed/duplex
on fiber cards.

Cause: Missing checks for the case where autoneg is off.

Change: Added proper checks.

Impact: No.

v1.1.11 (Feb. 18, 2005)
======================
Enhancements:
-------------
1. Change: (CQTO901) Added bnx2(4) man page.

Impact: None.

v1.1.10 (Feb. 16, 2005)
======================
Fixes:
------
1. Problem: Wrong device ID in pci_dev_id table.

Change: Fixed ID.

Impact: None.

v1.1.9 (Feb. 10, 2005)
======================
Fixes:
------
1. Problem: (CQTO771) Driver fails to compile on RHEL3 update 4.

Cause: The RH kernel has back-ported some netif functions
not found in the same vanilla kernel version. Duplicate
function names are defined.

Change: Added intelligence in Makefile to detect such conditions
and change the CFLAGS accordingly.

Impact: None.

2. Problem: (CQTO1017) Driver allows 1000 half duplex autoneg off.

Cause: Missing validity check.

Change: Added check.

Impact: None.

Enhancements:
-------------
1. Change: The code to handle tx queue full condition was redone
to properly handle all boundary and race conditions.

Impact: Minimum tx ring size is now MAX_SKB_FRAGS+1.

2. Change: Tx timeout code was changed to work queue context.
This allows netif to be shutdown gracefully before
chip reset.

Impact: None.

3. Change: Added memory barriers to ISR and NAPI poll for
correctness.

Impact: None.

v1.1.8 (Feb. 01, 2005)
======================
Fixes:
------
1. Problem: (CQTO969) No interupts on a system that does not
support MSI.

Cause: On this system, the MSI generated in the MSI test
terminates with Master Abort which is a fatal
condition for the chip.

Change: A chip reset is added when MSI test fails to bring
the chip back to normal operations again (in INTx mode).

Impact: None.

Enhancements:
-------------
1. Change: Removed register 0x84 from the ethtool register test.
This is an interrupt control register that should
not be touched to prevent unwanted interrupts.

Impact: None.

v1.1.7 (Jan. 28, 2005)
======================
Enhancements:
-------------
1. Change: Added interrupt test when MSI is enabled. If MSI test
fails, driver will fallback to INTx mode.

Impact: None.

2. Change: Added test for certain chipsets where MSI is known
to fail, and disable MSI unconditionally when
such chipsets are found.

Impact: None.

3. Change: Removed support for 1000 Mbps half duplex.

Impact: 1000 Mbps half duplex will no longer work.

v1.1.6 (Jan. 26, 2005)
======================
Fixes:
------
1. Problem: (CQTO940) MTU size not set properly when device is down.

Cause: bnx2_change_mtu only handled the "up" case.

Change: Simple fix to handle the "down" case as well.

Impact: None

2. Problem: (CQTO926) 5706S does not autoneg properly after the
tx cable is pulled.

Cause: If the link partner is autonegotiating, autoneg will
fail when the tx cable is pulled. The software will
turn off autoneg seeing that the rx cable is still
attached with SIGNAL_DETECT. When the tx cable is
re-attached, autoneg is still off and the link partner
will not establish link.

Change: Added code to poll another PHY register to check if
configs are received when autoneg is disabled.

Impact: None

Enhancements:
-------------
1. Change: Added OEM product name strings.

Impact: None.

v1.1.5 (Jan. 25, 2005)
======================
Fixes:
------
1. Problem: PCI-X bus speed may not be detected correctly by the driver,
causing failure because certain register settings are done
based on bus speed.

Cause: hardware problem.

Change: Use a different register to detect PCI-X speed.

Impact: None.

v1.1.4 (Jan. 17, 2005)
======================
Fixes:
------
1. Problem: 5706S does not reliably detect link up or down.

Cause: hardware problem.

Change: Enabled hardware workaround which is effective in
A2 and newer chips only.

Impact: None.

v1.1.3 (Jan. 13, 2005)
======================
Fixes:
------
1. Problem: netdump does not work.

Cause: poll_controller routine does not work in NAPI mode.

Change: Fixed poll_controller routine for NAPI mode.

Impact: None.

Enhancements:
-------------
1. Change: Added the new mmiowb macro which is used mainly in NUMA
machines to guarantee PCI ordering.

Impact: None.

2. Change: Added OEM product name strings.

Impact: None.

3. Change: Changed ONE_TDMA workaround on systems with P64H bridge to
PING_PONG_DMA on all systems using PCI.

Impact: Better performance and better compatibility on all PCI
systems.

4. Change: Added "disable_msi" parameter to allow disabling MSI.

Impact: None.

5. Change: Reduced default tx coalescing parameters for better
tx only performance such as ttcp.

Impact: None.

6. Change: Changed NIC detection console message to display more
information.

Impact: None.

7. Change: Cleaned up some Linux .h files that are not needed.

Impact: None.

8. Change: Cleaned up the nvram routines.

Impact: None.

v1.1.2 (Nov. 11, 2004)
======================
Fixes:
------
1. Problem: Unable to load the driver on more than 2 or 3 devices.

Cause: Default register space is too big. System fails to map
the register space on the 3rd or 4th device.

Change: Changed driver to map a smaller register space as the higher
registers are not needed for standard operations.

Impact: None.

v1.1.1 (Nov. 9, 2004)
======================
Fixes:
------
1. Problem: (CQTO656) One remaining ethtool parameter can be set out of
range.

Cause: Wrong upper bounds in code.

Change: Fixed upper bound.

Impact: None.

1. Problem: 5706 A1 cannot be run on a PCI bus.

Cause: Hardware errata.

Change: Added workaround to detect 5706 A1 on PCI bus and abort.

Impact: Driver will not load 5706 A1 on PCI bus.

v1.1.0 (Oct. 29, 2004)
======================
Fixes:
------
1. Problem: (CQTO663) No link on fiber NIC set to autoneg when
the link partner is set to forced speed.

Cause: No code to handle this case.

Change: Added code to check SIGNAL DETECT when autoneg fails,
and turn off autoneg when appropriate. Also added code
to force a link down when speed settings are changed.

Impact: None.

2. Problem: (CQTO649) ifconfig up/down can cause system to
hang on 2.6 kernels using mmconfig.

Cause: Dummy read in the kernel's pci_mmcfg_write routine
may cause system to hang during D3hot -> D0
transition. The PLL may lose lock during the internal
D0 transition chip reset and cause the dummy read to
hang.

Change: The PLL problem will be fixed in A2. Meanwhile, the
driver is changed to go into D3hot only if wol is
enabled.

Impact: Minor impact in increased power consumption when
the driver is shutdown with wol disabled.

3. Change: Changed to use pci_get_device as pci_find_device
will be deprecated soon.

Impact: None.

4. Problem: (CQTO656) Some ethtool parameters can be set out of range.

Cause: Wrong upper bounds in code or documentation.

Change: Fixed code and documentation.

Impact: None.

v1.0.15 (Oct. 15, 2004)
======================
Fixes:
------
1. Problem: (CQTO644) Data corruption when sending FTP traffic on
Dell Precision 530MT.

Cause: PCI bridge errata.

Change: Added code to enable ONE_TDMA workaround when P64H
PCI bridge is detected.

Impact: Slower tx performance on systems using P64H bridge.

2. Problem: (CQTO643) Driver allows MTU to be set up to 9004.

Cause: Driver used the wrong upper bound limit.

Change: Fixed the upper bound.

Impact: None.

3. Problem: Driver does not support forced speed on 5706S.

Cause: Missing software logic.

Change: Added code to support forced 1000 Full and Half duplex.

Impact: None.

4. Change: Added workaround to disable PERR generation on
5706 A1 when it is in PCI 64-bit slot.

Impact: None.

v1.0.14 (Oct. 05, 2004)
======================
Fixes:
------
1. Problem: Driver load/unload hangs on some machines.

Cause: Transition delay required during D3hot -> D0 transition.

Change: Added necessary delay.

Impact: None.

v1.0.12 (Oct. 04, 2004)
======================
Fixes:
------
1. Problem: (CQTO609) New flow control parameter does not take
effect until ifdown/ifup or link down/up.

Cause: New flow control settings are only configured during
link up. The driver did not check flow control
advertisement changes and therefore no re-negotiation
and no link down.

Change: Fixed logic so that link will always go down whenever
there is a change a flow control advertisement.

Impact: None.

2. Problem: (CQTO612) VLAN packet reception not working.

Cause: VLAN #define not setup properly.

Change: Fixed #define for VLAN.

Impact: None.

3. Problem: (CQTO628) WoL not functioning correctly.

Cause: Multiple problems in the WoL code.

Change: Fixed by:
1. using sort mode.
2. setting up mac address correctly.

Impact: None.

Enhancements:
-------------
1. Change: Added support for non-dword and non-aligned write access
to eeprom, allowing ethtool -E to work.

Impact: None.

v1.0.11 (Sep. 24, 2004)
======================
Fixes:
------
1. Problem: (CQTO600) Kernel panic when attempting to ftp on
Fedora kernel.

Cause: skbuffs are 4-byte aligned on Fedora, causing
the rx headers to be misaligned. skbuffs are
16-byte aligned on other standard kernels.

Change: Removed any assumptions about skbuff alignment
and added code to align all rx skbuffs to 8-byte
boundaries.

Impact: None.

Enhancements:
-------------
1. Change: Added netif_carrier_off to Driver init code so that
the initial link state is off.

Impact: None.

v1.0.10 (Sep. 23, 2004)
======================
Fixes:
------
1. Problem: (CQTO599) Driver fails to compile on RH 3.0ES.

Cause: Bug in poll_bcm5706 where bp is referenced without
being defined.

Change: Fixed the minor bug.

Impact: None.

v1.0.9 (Sep. 23, 2004)
======================
Fixes:
------
1. Problem: Jumbo frames not working reliably.

Cause: Bug in bcm5706_reuse_rx_skb.

Change: Fixed the bug so that the host address is properly
copied from one BD to the other.

Impact: None.

Enhancements:
-------------
1. Change: Change the locking scheme for more reliable open/close/ioctl
operations where the spinlock is needed.

Impact: None.

2. Change: Added minimum MTU size check for MTU changes.

Impact: None.

v1.0.8 (Sep. 20, 2004)
======================
Fixes:
------
1. Problem: (CQTO561) Kernel panic on RH30EL after repeated
driver load/unload.

Cause: Occasionally, the system is unable to map device
registers, causing subsequent register access to fail.

Change: Added check for the return value from ioremap, and exit
gracefully if it fails.

Impact: None.

2. Problem: (CQTO574) NETDEV WATCHDOG when running 5706 A1 on
PCIX 133MHz slot.

Cause: Some hw register setup required for 133 Mhz.

Change: Added the register setup code.

Impact: None.

3. Problem: (CQTO468) Link does not go down after changing from
10Mbps full (forced) to 10Mbps half (forced) and vice versa
when the link partner is also using forced speed.

Cause: Delay not long enough for the link to go down.

Change: Not practical to increase delay as a very long delay is
needed for the link to go down. Added code to record the
proper link speed and duplex when speed is forced so that
ethtool will return the proper speed without the link going
down. Note that the link will go down if the link partner
has autoneg turned on, ensuring that the link partner will
see the link change.

Impact: None.

Enhancements:
-------------
1. Change: Added power management and WOL during device close. This
will allow WOL to work after Linux shutdown.

Impact: None.

2. Change: Changed driver so that ethtool will report invalid
speed after ifdown.

Impact: None.

3. Change: Updated tpatfw.h

Impact: None.

v1.0.7 (Sep. 14, 2004)
======================
Fixes:
------
1. Problem: (CQTO523) 5706 A1 hangs after a thousand iterations of
load/ifup/ifdown/unload.

Cause: The driver may be servicing an interrupt
within 15 msec of chip reset, causing the chip to hang.
The problem was aggravated by the timer mode
coalescing which created an excessive number of
interrupts (hardware problem).

The Driver may also occasionally see
the wrong firmware signature that will cause it to abort.

Change: Added synchronization to make sure all pending interrupts
are serviced before resetting the chip. Also changed to
collect mode coalescing. The firmware signature problem
will be fixed in boot code.

Impact: The use of collect mode coalescing may affect performance.

2. Problem: (CQTO558) Unable to load driver on some early 2.6 kernels.

Cause: pci_dma_sync_single_for_* routines not defined on early
2.6 kernels.

Change: Added compatibility defines for earlier kernels.

Impact: None.

v1.0.6 (Sep. 08, 2004)
======================
Fixes:
------
1. Problem: (CQTO523) 5706 A1 hangs during repeated driver ifup/down.

Cause: No delay after chip reset for A1.

Change: Added 15 msec delay after chip reset for A1.

Impact: None.

2. Problem: (CQTO468) Link does not go down after changing from
10Mbps full (forced) to 10Mbps half (forced) and vice versa.

Cause: Not enough delay after forcing link down.

Change: Added proper delay for link to go down.

Impact: None.

v1.0.5 (Sep. 02, 2004)
======================
Enhancements:
-------------
1. Change: Added support for ethtool -c, ethtool -C, ethtool -p,
and firmware version for ethtool -i.

Impact: None.

Fixes:
------
1. Problem: 5706C not advertising 1000 half duplex.

Cause: 1000 full duplex overwrites 1000 half duplex.

Change: Fixed the bug so that the 2 bits are or'ed together.

Impact: None.

2. Problem: ethtool -A does not change the flow control settings
in all cases.

Cause: Flow control settings not zeroed out before setting new
values.

Change: Minor bug fix to zero out the value.

Impact: None.

v1.0.4 (Sep. 02, 2004)
======================
Fixes:
------
1. Problem: (CQTO504) Multiple NFS transfers will hang some
connections.

Cause: Driver discards some receive packets when the
error status is non-zero.

Change: Changed the driver to only discard receive packets
when the defined error bits in the error status are
non-zero.

Impact: None.

v1.0.3 (Sep. 01, 2004)
======================
Enhancements:
-------------
1. Problem: Driver does not support ethtool -t self test and
ethtool -S statistics.

Change: Added ethtool self test and statistics.

Impact: None.

Fixes:
------
1. Problem: (CQTO478) Kernel still panics when transmitting certain
files using NFS after many iterations

Cause: Tx DMA stalls on certain UDP packets, causing NFS
client to stall.

Change: More fixes made in firmware.

Impact: None.

v1.0.2 (Aug. 26, 2004)
======================
Enhancements:
-------------
1. Problem: Driver does not work on big endian machines.

Change: Ported and tested on SPARC64 machine.

Impact: None.

Fixes:
------
1. Problem: (CQTO478) Kernel panics when transmitting certain
files using NFS.

Cause: Tx DMA stalls on certain UDP packets, causing NFS
client to stall.

Change: Fixed in firmware.

Impact: None.

2. Problem: (CQTO469) Unable to modify flow control parameters

Cause: Did not call setup_phy after the parameters are changed.

Change: Added call to setup_phy after parameters are changed.

Impact: None.

3. Problem: (CQTO467) 5706 does not autonegotiate properly after
changing settings with ethtool.

Cause: This is an ethtool limitation as the proper advertising
parameters are not passed to the driver properly.

Change: Implemented a new scheme to work around the problem to
allow users to specify full autoneg, single speed autoneg,
and fixed speed.

Impact: None.

4. Problem: ethtool -e does not work.

Cause: Various bugs in the nvram routines.

Change: Fixed and tested nvram routines on little endian and big endian
machines.

Impact: None.

v1.0.1 (Aug. 18, 2004)
======================
Fixes:
------
1. Problem: (CQTO459) 5706 NIC does not get link.

Cause: Boot code timing out in WAIT2 state before driver is ready.

Change: Moved the WAIT2 state ahead in the driver reset sequence
as a temporary workaround until it is fixed in boot code.

Impact: None.

2. Problem: (CQTO463) Kernel panics when loading the driver on
RH30EL (2.4.21-4.EL)

Cause: Older kernel used different API to allocate and register
netdev.

Change: Added older APIs to be used on older kernels.

Impact: None.

v1.0.0 (Aug. 13, 2004)
======================
Initial release

All rights reserved.

Version 1.62.17 (Mar 23, 2011)
==============================
Fixes
-----
1. Problem: ethtool show the wrong port connected.

Cause: Dual media port presentation was swapped.

Change: Show the active port.

Impact: Introduced: 1.62.16.
Dual media boards.

2. Problem: (CQ52000 Cont) 1G link is broken on 8727PHY and 8706PHY.

Cause: Mechanism to check XAUI fault on 10G does not work on 1G.

Change: Only check XAUI fault on 10G.

Impact: 8727PHY and 8706PHY based boards.

3. Problem: (CQ51134) NC-SI functionality dependant on Port initialization
Sequence.

Cause: During common init, the driver resets both BMACs such that if
NCSI was enabled on the other port, it will stop working.

Change: BMAC will be reset during port initialization only.

Impact: 5771x with NCSI enabled.

Version 1.62.16 (Mar 15, 2011)
==============================
Fixes
-----
1. Problem: Packets that target FCoE L2 ring are duplicated when interface
is in a promiscuous mode.

Cause: Packets were arriving to stack from both L2 RSS and from FCoE
L2 in a promiscuous mode.

Change: Configure FCoE L2 ring to DROP_ALL rx mode, when interface is
configured to PROMISC, and to accept only unicast frames, when
interface is configured to ALL_MULTI.

Impact: FCoE only.

2. Problem: Possible packet corruption when resetting the primary interface
when there are VLAN interfaces configured for this interface.

Cause: VLAN HW acceleration (stripping) is configured after Rx packets
are allowed at the end of netdev->open().

Change: Configure VLAN stripping in Client SETUP if there are VLAN
interface already configured for this interface.

Impact: Kernels below 2.6.37. Introduced in 1.62.01.

3. Problem: ESX. Non LRO net-queues allocated when LRO queues are
requested.

Cause: The LRO flag tested when an LRO queue was requested is
inverted.

Change: Mark queues as LRO/Non-LRO appropriately.

Impact: ESX only.

4. Problem: (CQ53457) in MF mode actual TX max bandwidth differs from
configured for the device.

Cause: non-pmf function has overwritten configuration according to
10G link speed in UP flow.

Change: Fix device load flow for non-pmf functions.

Impact: MF mode with link speed other than 10G.

5. Problem: (CQ5772) (NPAR) Some configuration of Bandwidth Weight and
Maximum Bandwidth is not functional.

Cause: MAX algorithm timer was set to smaller value then MIN
algorithm. In some cases this may cause under-run on the line.

Change: Increase MAX algorithm timeout from 100usec to 400usec.

Impact: Inroduced in 1.64.09.

6. Problem: (CQ53427) ethtool reports incorrect info for 10GE Passive
Copper Cable connections.

Cause: Cable type was not taken into consideration.

Change: Determine port type using cable type information acquired from
external SFP+ module if exists.

Impact: SFP+ type.

7. Problem: (CQ53414) bnx2x reports link down when loaded.

Cause: The code was set to report the link state on load time.

Change: Assume the link is down when loading and only report link up
after loading.

8. Problem: Rx and Tx coalescing timeout parameters are reversed.

Cause: Parameters passed erroneously between functions.

Change: Swapped parameters in function call.

Impact: Bug exists in all bnx2x versions supporting interrupt
coalescing.

Enhancements
------------
1. Request: Configure a mini-jumbo (2500) MTU for FCoE L2 ring. Don't
change it when NIC's MTU changes.

Change: As requested.

2. Request: Allow set speed in NPAR mode when device still closed.

Change: As requested.

3. Request: (CQ52000 & CQ51134 Cont.) Short on XAUI lanes on the MAC side
of 8727 PHY needs to generate link down event.

Change: Tx fault detection has been added. In addition link
qualification includes checking for Tx fault. The fault
detection bit is read twice to clear any stale value.

Impact: 8727 PHY.

4. Request: (CQ51697) Short on XAUI lanes on the MAC side of 8706 PHY
needs to generate link down event.

Change: Tx fault detection has been added. In addition link
qualification includes checking for Tx fault. The fault
detection bit is read twice to clear any stale value.

Impact: 8706 PHY.

5. Request: (CQ50798) Add support for BCM8722.

Change: As requested.

Version 1.62.15 (Feb 10, 2011)
==============================
Fixes
-----
1. Problem: (CQ52536) Extra bytes might be added in the middle of the
payload when a packet with padding after the TCP payload is
received, while TPA is enabled.

Cause: Firmware wrongly places padding bytes on RX SGEs.

Change: (In FW 6.2.7) Fixed relevant firmware flow.

Impact: The problem will be exposed only in very rare case in which a
device on the network pads the Ethernet packet to longer than
72 bytes.

Enhancements
------------
1. Request: Use FW 6.2.7

Change: As requested.

Version 1.62.14 (Feb 03, 2011)
==============================
Fixes
-----
1. Problem: (CQ52402) In NPAR mode setting some speed via ethtool -s causes
device to hang.

Cause: FW configured with illegal configuration.

Change: Limit allowed speed to range from 1%-100% of actual line speed.

Impact: NPAR mode only.

Version 1.62.13 (Feb 01, 2011)
==============================
Fixes
-----
1. Problem: (CQ52656) In NPAR mode "ethtool -t ethX" does not report error
on some partitions while no link.

Cause: Link is not tested for non PMF partitions.

Change: Allow link testing for non PMF partitions.

Impact: NPAR mode only.

2. Problem: Unresolved bnx2x_invalidate_uc_list symbol on kernels
below 2.6.23.

Cause: Missing #if block preventing the usage of the above function
while it's only implemented for kernels above 2.6.23
(including).

Change: Added a missing #if block.

Impact: Kernels below 2.6.23.

Version 1.62.12 (Feb 01, 2011)
==============================
Fixes
-----
1. Problem: (CQ52402) In NPAR mode "ethtool -s ethX speed 0" causes
device to hang.

Cause: FW configured with illegal configuration.

Change: Do not allow speed 0.

Impact: NPAR mode only.

Enhancements
------------
1. Request: Add support for dev_uc_add()/dev_mc_add().

Change: As requested.

Version 1.62.11 (Jan 24, 2011)
==============================
Fixes
-----
1. Problem: ifup returned error when device has illegal iSCSI mac.

Cause: FCoE/iSCSI features were enabled even with illegal mac.

Change: Disable the features if mac is illegal.

Impact: 57712 SF mode.

2. Problem: CQ52212 8073PHY intermittently exhibits signs of disconnected
devices upon loading/unloading.

Cause: Microcontroller and Driver both controlling Xaui Low Power
Mode.

Change: Remove Driver control of Xaui Low Power Mode.

Impact: 8073 PHY based boards.

3. Problem: CQ51624 PHY TXONOFF_PWRDN_DIS bit set to "1" instead of default
0 to prevent reset & power down of PHY.

Cause: When GPIO controls TX Laser on 8727 and 8706, turning off laser
will put PHY in low power mode.

Change: Set TXONOFF_PWRDN_DIS accordingly.

Impact: 8727PHY and 8706PHY based boards with TX laser controlled by
GPIO_0.

4. Problem: Potential wrong PHY initialization when loading the first
function on a port, after another function from this port was
unloaded.

Cause: In this case, the driver won't lock PHY access, which may cause
MDC/MDIO collision.

Change: Initialize the lock flag on the init driver stage, instead of
the common and port init stage.

Impact: Multi-function mode.

Version 1.62.10 (Jan 17, 2011)
==============================
Fixes
-----
1. Problem: "Statistics sequence counter out of order" strom assert.

Cause: Race between the LINK_UP event handler and the timer which both
are calling the bnx2x_storm_stats_post() thus sending
consequent statistics ramrods without waiting for a
completion of the first. Therefore FW will read the ramrod data
of the second ramrod while handling the first one, which will
cause the above assert.

Change: Prevent the above race.

2. Problem: (FCoE) There was no licensing for FCoE.

Cause: Missing FCoE licensing handling code.

Change: Added the missing code.

Impact: FCoE only.

3. Problem: The module date was not updated since 2010/08/01.

Cause: The date was moved to another source file which did not updated
it automatically on submission to the version control system.

Change: Update the file properties so the version control system will
update the date automatically.

Impact: Introduced in 1.60.32.

4. Problem: Compilation error on some older vanilla kernels.

Cause: Improperly handling gso v6 feature by compat.

Change: Fix handling in bnx2x_compat.h.

Impact: Introduced in 1.62.06.

5. Problem: ESX - When there's a single netqueue (num_queues=2),
it can never be allocated for RX.

Cause: When there's a single netqueue it is set aside as an LRO
queue, but ESX does not put any queues in the LRO pool.

Change: Set aside queues 2 and 4 for LRO instead of 1 and 3.

Impact: ESX only.

6. Problem: (CQ52276) Unable to bring up device when iSCSI is not allowed.

Cause: Driver tried to enable feature, but failed due to illegal mac.

Change: Disable the feature if not allowed.

Impact: 57712 SF mode. Introduced in 1.62.09.

Version 1.62.09 (Jan 03, 2011)
==============================
Fixes
-----
1. Problem: All multicast packets were arriving to all L2 clients.

Cause: All queues were configured to accept all multicast packets in
NPAR.

Change: Fix Rx mode configuration code in bnx2x driver.

Impact: NPAR only. Introduced in 1.60.09.

2. Problem: (CQ51731) Kernel paniced after "ethtool -d" test.

Cause: Registers dump caused MCP SPAD parity error, which caused
"close the gates" flow in HW, which in line caused undefined
behaviour of the whole system.

Change: Prevent HW blocks parity attentions during registers dump
routine.

3. Problem: ESX - CNIC 'change MTU' would fail or result in a PSOD.

Cause: Mismatched module IDs for request/free IRQ.

Change: Masquerade as CNIC when cnic ops are called form bnx2x.

Impact: ESX only.

4. Problem: Possible sending of a spurious MSI-X message after MSI-X is
disabled.

Cause: MSI-X configuration wasn't properly cleared when MSI-X was
disabled.

Change: Properly clear MSI-X configuration.

Impact: Introduced in 1.60.28.

5. Problem: (NPAR, FCoE) FCoE MAC wasn't read in NPAR mode.

Cause: Missing code.

Change: Add the missing code.

Impact: FCoE in NPAR mode only.

6. Problem: (iSCSI) If iSCSI offload is requested in switch dependent MF
mode zero MAC would be configured for iSCSI L2 queue.

Cause: Bug in a driver.

Change: Prevent the configuration of an illegal MAC.

Impact: iSCSI in switch dependent mode only.

Enhancements
------------
1. Request: (CQ51889) Add Common Mode Sense (CMS) enable/disable
functionality.

Change: Adding field 156 to nvm cfg, as well as support in eLink.

Impact: NVM config and Common Mode Sense capable PHYs.

2. Request: Add dcbnl implementation supporting the FW DCBX engine.

Change: As requested.

Impact: 57712 only.

Version 1.62.08 (Dec 20, 2010)
==============================
Fixes
-----
1. Problem: (CQ51134) NC-SI functionality dependant on Port initialization
Sequence

Cause: When the driver loads the first port, some PHYs require reset
and loading their microcode on both ports. In case NCSI was
enabled on the other port, the traffic was stopped since PHY
was reset

Change: Load PHY microcode during common init, only if the PHY
microcode wasn't loaded

Impact: Requires bootcode 6.2.9 to resolve this problem
PHY firmware upgrade will require reboot from now on

2. Request: Increase RX ring size to 512 when using Jumbo Frames

Change: As requested

Impact: ESX only

3. Request: Enable OOO by default and have the OOO ring match
in size with a RX ring

Change: As requested

Impact: ESX only

4. Problem: (CQ51367) - BCM84823/84833 activity LED blinks at lower rate on
10G link

Cause: The activity LED control registers are not configured right

Change: Enabled activity LED stretch_en bit. Made activity LED blink on
source

Impact: BCM57712 + BCM84823/84833 based boards

5. Problem: (CQ51413) Driver crashed, when number of queues was set to a
value smaller than a default one due to SAFC configuration

Cause: Broken connection between an SAFC initialization and a memory
allocation code

Change: Fixed the above flaw

Impact: SAFC only. Introduced in 1.62.06

Enhancements
------------
1. Request: CQ51710 - Disable CMS (common mode sense) feature in 84823
PHY, as this reduces power consumption and allows a better
10G link stability

Change: Clear the CMS bit in PHY register in PHY configuration routine

Impact: BCM84823B based boards

2. Request: Re-introduce the dropless_fc vmkernel module parameter

Change: As requested

Impact: ESX only

3. Request: BCM8727 Link LED not funtioning properly during BACS LED test

Change: Not blinking correct link light

Impact: BCM57712 + BCM8727 based boards

Version 1.62.07 (Dec 15, 2010)
==============================
Fixes
-----
1. Problem: (iSCSI, CQ50571) TCP connection erroneously closed

Cause: TCP window was closed due to out-of-order state, and initiator
failed to send a window update when exiting out-of-order state

Change: Fixed in FW 6.2.5

Impact: Introduced in 1.60.00

2. Problem: (CQ51171) One CX4 blade design does not autoneg to link up
at 10G with a particular switch.

Cause: The autoneg was not enabled due to incorrect setting at the
XGXS AER

Change: Update the XGXS AER to devad 7 to allow proper configuration of
autoneg

Impact: 57712 only

3. Problem: (iSCSI, CQ50380) TCP window was closed due to out-of-order
state, and initiator failed to send a window update when
exiting out-of-order state

Cause: Malformed message is sent by FW from Tstrom to Xstorm

Change: Fixed in FW 6.2.6

Impact: iSCSI OOO only. Introduced in 1.60.15

Enhancements
------------
1. Request: Use FW 6.2.6

Change: As requested

2. Request: (CQ48296), (CQ51540) Add support for new BCM8727 boards

Change: As requested

Impact: BCM8727 based boards

Version 1.62.06 (Dec 2, 2010)
==============================
Fixes
-----
1. Problem: (CQ50681) Device hangs on up/down test when PFC is enabled

Cause: If the device is going down while in PFC Xoff it will not set
it to Xon and therefore, on the next load it will remain in
constant Xoff

Change: Force PFC Xon when enabling the device

Impact: 57712 only

2. Problem: ethtool -t failed on single port boards and 57712 (nvram test)

Cause: Erroneous access to unexistent port info

Fix: remove the access

3. Problem: PCI bus error when trying to transmit LSO packets from 57712 on
Big Endian machines

Cause: Parsing BD parsing_data field was malformed when running
57712 on Big Endian machines

Fix: Fix the code handling the parsing_data field of a parsing BD
for 57712

Impact: Introduced in 1.53.0a, 57712 only

4. Problem: Kernel panic when receiving in none-MSI-X interrupt mode

Cause: Indirection table was configured with none-existing queues when
MSI-X was not attainable and RSS queues set was cut to a single
queue. The reason for the above was an improper location of
SAFC initialization code and usage of the SAFC parameters for
the indirection table configuration despite the fact that an
SAFC MF mode was not requested/not available

Fix: Don't use SAFC parameters unless SAFC MF mode is requested

Impact: Introduced in 1.60.30

5. Problem: (CQ48350, CQ49176, CQ50911, CQ51200) BCM57712 not linking up
after system waked up

Cause: PHY firmware does not have enough time to download in 8073 and
8727 common init

Fix: Poll until PHY firmware is downloaded, and then timeout at
300ms

Impact: 8727 and 8073 PHYs

Version 1.62.05 (Nov 26, 2010)
==============================
Fixes
-----
1. Problem: A possible dead-lock situation between sch_direct_xmit() and
bnx2x_run_loopback() (calling bnx2x_tx_int()) on
netif_tx_lock()

Cause: Both functions above take a netif_tx_lock() but
bnx2x_run_loopback() is called in a syscall context and takes a
lock without disabling BHes on a local CPU, which may cause a
dead lock as long as sch_direct_xmit() is called in a
soft_irq() context

Fix: Explicitly disable local BHes in bnx2x_run_loopback() to
prevent a mentioned above dead-lock situation

Impact: Introduced in 1.60.25

Enhancements
------------
1. Request: Integrate VLAN enhancements from the net-next

Change: As requested

2. Request: (NPAR) Restore set speed ethtool interface to use absolute
speed instead of percents

Change: As requested

Impact: NPAR mode only, introduced in 1.62.04

Version 1.62.04 (Nov 17, 2010)
==============================
Fixes
-----
1. Problem: Duplex status may be displayed incorrect

Cause: Missing duplex configuration in some external PHYs when link
goes up

Change: Set duplex to FULL when 10G link comes up

2. Problem: 57712 incorrect PCIX interface speed reported to user

Cause: Improper print

Change: Fix print

Impact: 57712 only

3. Problem: (FCoE, NPAR) FIP mac is not configured in NPAR mode

Cause: FIP configured for SF only

Change: Add NPAR mode

Impact: 57712 NPAR mode only

4. Problem: (CQ51015) nx2 Package 6.2.5 has error when compile on RH6.0

Cause: cnic_if.h included before if_vlan.h

Change: Move if_vlan.h before cnic_if.h

Impact: Introduced in 1.62.01

5. Problem: Compilation failed when kernel configured without 8021Q

Cause: Improper #ifdef structure

Change: Fix the #ifdef structure to suit the configuration

Impact: Introduced in 1.62.01

6. Problem: (CQ50672) Chip hangs when running iSCSI traffic on one function
and toggling load/unload on the other function

Cause: Firmware initialized the CAM incorrectly, causing iSCSI out of
order client to receive an unexpected packet

Change: (Fixed in FW 6.2.3) Fixed firmware flow

Impact: Introduced in 1.60.01, BCM57710 only

7. Problem: (CQ50748) MinBW not functioning as expected in certain
NPAR configuration

Cause: MinBW algorithm coefficients were not calculated properly and
cause the algorithm to not function well in extreme cases

Change: Re-calculate the algorithm coefficients to allow
granularity of 1:100

Impact: Affects NPAR mode in which MAX bandwidth can be configured
to over-subscription

6. Problem: Compilation failed on RH5.6

Cause: Redefinition of backported function

Change: Remove the definition from bnx2x code for RH5.6

Enhancements
------------
1. Request: Use FW 6.2.3

Change: As requested

2. Request: (CQ51065) NPAR mode: change Max BW from units of "intervals of
[100Mbps]" to units of "% of physical link speed"

Change: As requested

Impact: NPAR mode only

Version 1.62.03 (Nov 10, 2010)
==============================
Fixes
-----
1. Problem: (CQ50559) Build fails with RHEL6 kernel

Cause: Redefinition of backported function

Change: Remove the definition for RH kernels

Impact: Introduced in 1.62.01

2. Problem: Compilation failed on 2.6.36 kernels

Cause: Improper conditions in bnx2x_compat.h layer

Change: Fix condition for functions' definitions

3. Problem: (CQ50903) Driver prints some debug info when dcbx enabled

Cause: Debug info printed with error dbg level

Change: Remove the prints

4. Problem: False bug-check when trying to set speed in NPAR mode when link
is down

Cause: The FW should be configured only after the physical link is up

Change: Do not configure the FW while link is down with the new speed
settings

Impact: 57712 NPAR mode only

5. Problem: (iSCSI) (CQ50380) Offloaded connection eventually closed

Cause: TCP window is closed and initiator cannot properly process
incoming in-order packets

Change: (in FW 6.2.2) Fixed firmware flow

Impact: Introduced in 1.60.01

6. Problem: (iSCSI) in NPAR mode devices have incorrect iscsi mac address

Cause: Mac address was taken from port configuration

Change: Take the mac addresses from NPAR configuration

Enhancements
------------

==============================
Fixes
-----
1. Problem: (CQ49515 & CQ50024) Occasionally losing link on force 10/100
connections on BCM84823 based boards

Cause: Not waiting for GPHY to complete reset

Change: Add 50ms delay after 84823 PHY comes out of reset

Impact: BCM84823 based boards

2. Problem: (CQ50623) MF is not functional on single CPU systems

Cause: Improper FW configuration when only one queue configured

Change: Allow FW configuration when only one queue configured

Impact: Introduced in 1.62.01

3. Problem: Possible race between the netdev->open() and the last part of
pci_dev->probe() that configures the interrupt mode and adds
NAPIs

Cause: Improper operations order: netdev_register() should be called
after driver is completely configured

Change: Move all driver initializations before the netdev_register()
call

Impact: Introduced in 1.60.28

Enhancements
------------
1. Request: (CQ50053) Add "Dual Media Support" section to README/Man pages

Change: As requested

Version 1.62.01 (Oct 20, 2010)
==============================
Fixes
-----
1. Problem: (CQ49888) Can't pass VLAN Tagged packets when CAP_VLAN_RX & TX
are disabled

Cause: VLAN HW acceleration was performed regardless the value of the
runtime NETIF_F_HW_VLAN_RX/NETIF_F_HW_VLAN_TX netdev
capabilities

Change: Consider NETIF_F_HW_VLAN_RX/NETIF_F_HW_VLAN_TX netdev
capabilities when enabling or disabling VLAN HW acceleration
capability

Impact: ESX only. Introduced in 1.60.11

2. Problem: (CQ49375) VLAN tag was stripped from the packet when there were
no VLAN interfaces configured

Cause: HW VLAN stripping was always configured

Change: Don't configure HW VLAN stripping if there are no VLAN
interfaces configured for the current device

3. Problem: iSCSI OOO didn't work over VLAN

Cause: Inconsistent Client configuration and fast path functions
implementation for OOO Client in regard to HW VLAN
acceleration

Change: Don't assume HW VLAN acceleration in fast path iSCSI OOO
functions

Impact: iSCSI OOO only

4. Problem: (PR609549) vsish pNic general statistics always showed 0

Cause: The incorrect stats struct was given to the vmkernel.
The private data stats struct was given to the vmkernel
rather then the stats struct in the net_device struct

Change: When the vmkernel is requesting for the stats, return the stats
struct used by ESX 4.x (netdev->stats)

Impact: ESX4.x only

5. Problem: (CQ49886) MC Assert on 57710 with more than 4 queues

Cause: ESX does not align physical memory to requested size. Thus ILT
pages do not adhere to 57710 alignment requirements

Change: Allocate extra memory and manually align CDU ILT pages. Define
ILT pages for all other clients to be 4K

Impact: ESX only. Introduced in 1.60.01

6. Problem: (ESX) LRO (TPA) not enabled for 4.1

Cause: __NO_TPA__ CFLAG defined for all ESX releases

Change: Define __NO_TPA__ only for ESX releases below 4.0

Impact: ESX only. Introduced in 1.60.01

7. Problem: On ESX 4.1, not all 8 queues are exposed for BCM57711

Cause: When reducing the number of queues for ESX 4.0
ESX 4.1 was also effected

Change: At compile time, allow for 8 queues for ESX 4.1 and
4 queues for ESX 4.0

Impact: ESX only. Introduced in 1.60.43

8. Problem: (CQ50111) Unload/Load driver in MSI mode causes kernel warning

Cause: pci_enable_msi() called during open()

Change: move pci_enable_msi() to init_one()

Impact: Introduced in 1.60.28

9. Problem: (CQ50208) ESX4.0/4.1 pNic statistics are not updated

Cause: Using a local statistics structure for ESX instead of the
net_device statistics structure

Change: Use the correct statistics structure for ESX

Impact: ESX only

10. Problem: (CQ50033) Link remains down on the PMF despite the DCC
"link up" indication

Cause: DCC event handler wasn't handling the event for the PMF

Change: Fix the DCC event handler code

Impact: 57711 and 57712 only

11. Problem: Link up event is not reported to the OS

Cause: Inconsistent link report state handling

Change: Change the link report state handling

12. Problem: (CQ50004, CQ50166) ESX4.1. TPA not working, netperf for LRO
net-queues fail

Cause: IP header offset is not computed correctly for ESX,
as a result the IP header checksum is not fixed correctly

Change: Correct the IP header offset computation

Impact: ESX only

13. Problem: All traffic comes to RX queue 0

Cause: Missing RSS enablement code

Change: Add missing code

Impact: Introduced in 1.60.30

14. Problem: Xmit was stopping after a short time on the Flex-10

Cause: Wrong parsing of the MIN_MAX configuration in the SHMEM

Change: Revert the parsing logic to what it was before 1.60.47

Impact: Introduced in 1.60.47

15. Problem: (ESX) Non LRO net-queues were still aggregating incoming TCP
frames

Cause: net-queues not reserved for LRO were not internally marked
as such (tpa not disabled)

Change: correctly disable tpa fpr such queues

Impact: ESX only, Introduced in 1.60.48

16. Problem: (CQ50411) All traffic comes to RX queue 0

Cause: Missing RSS enablement code

Change: Add missing code

Impact: Introduced in 1.60.30

17. Problem: (ESX) Bad IP checksum for TPA packets over VLAN when VLAN
acceleration is disabled

Cause: IP header offset wasn't properly calculated in the case
mentioned above

Change: Don't move the IP header pointer in VLAN none-accelerated case
as eth_header_len() has already taken it into an account

Impact: ESX only

18. Problem: (CQ50080) Link up event is not reported to the OS

Cause: Inconsistent link report state handling

Change: Change the link report state handling

Impact: Introduced in 1.60.47

19. Problem: (CQ49827, CQ49844) pNic Link/Unlink test fails when the pNic
eventually fails to load

Cause: During load skb allocation for L2 queues is stopped on the
first failure. If this happens on the default queue before a
minimal number of skbs were successfully allocated nic load
fails

Fix: Do not break upon first skb allocation failure. Fail only if
after queues size allocation attempts not enough skbs were
successfully allocated

Impact: ESX only

20. Problem: (CQ49826) Wrong skb queue mapping passed to hard_xmit

Cause: FCoE L2 queue is not disabled and is used by the stack

Change: Disable FCoE L2 queue for E1x in general and all devices in
ESX

Impact: ESX only

21. Problem: (ESX) packets received on a net queue may arrive after its
filters are removed

Cause: Filter removal completion is not synchronized with the
net-queue fast-path completions

Change: Send a flush command for the net-queue after deleting the
filter and before returning from the filter removal call-back

Impact: ESX only

22. Problem: ethtool -S shows all possible queues including disabled queues
such as FCoE or queues with no stats such as iSCSI OOO queues

Cause: ethtool statistics call-backs iterate over all queues

Change: Iterate only over L2 queues and FCoE queue if not disabled

23. Problem: (ESX, PR379952/PR405074) FW asserts on invalid value in a VLAN
field in the start BD (xmit flow)

Cause: Invalid calculation of the headers length and, as a result,
invalid handling of packet dropping

Change: Check that the headers are in the first BD only for the LSO
packets. Properly calculate the headers length and drop the skb
if it's illegal

Impact: ESX only

24. Problem: (CQ49968) DMAE timeout on specific system during init

Cause: The DMAE can take up to 200ms to complete on some systems

Change: Update the DMAE timeout from 2ms to 200ms

ACK handling)

Change: As requested

Version 1.60.43 (Sep 16, 2010)
==============================
Fixes
-----
1. Problem: Performance regression on ESX4.x

Cause: Tx ring was configured to have a smaller length than it was in
IOVP driver

Change: Configure Tx ring to have the same length as in IOVP driver

Impact: ESX4.x only

2. Problem: (PR609549) vsish pNic general statistics always showed 0

Cause: The incorrect stats struct was updated. The private data
stats struct was updated rather then the stats struct
in the net_device struct

Change: When updating the stats, update the stats struct used
by ESX 4.x, the stats struct in the net_device struct

Impact: ESX4.x only

3. Problem: (CQ49760) No link on 10Gbase-T PHY on some systems

Cause: Not waiting until PHY has come out of reset

Change: Poll on reset bit. Timeout after 1 second

Impact: BCM84823 based boards

4. Problem: BCM8726 was not reset during common init

Cause: GPIO assert should have been swap due to board design

Change: Assert reset through the swapped GPIO port

Impact: BCM8726 based boards

Enhancements
------------
1. Request: Optimize fast path performance

Change: Optimized the branching in the bnx2x_rx_int() based on the
fact that FP CQE will always have at least one of START or
STOP flags set, so if not both bits are set and START bit is
not set, then it's a STOP bit that is set

Version 1.60.42 (Sep 13, 2010)
==============================
Fixes
-----
1. Problem: (CQ49795) Link loss on port after multiple iterations of
load-unload

Cause: When link change occur, and at the same time the driver is
unloaded, the NIG attention is left latched since it is used to
be cleared only during link change event. This leads that
following link change events are actually masked

Change: Clear NIG latched attention during driver unload

Impact: BCM84823 based boards

Version 1.60.41 (Sep 8, 2010)
==============================
Fixes
-----
1. Problem: (ESX) unload flow bails too early without properly releasing
resources and resetting the HW

Cause: Erroneous state validation causes early bail out form the
unload flow

Change: Fix the state validation condition

Impact: (ESX only) Introduced in 1.60.40

2. Problem: (ESX) ethtool -t (self-test) causes PSOD

Cause: Erroneous state validation causes early bail out form the
unload flow. As a result napi is not disabled and the next
load tries to re-enable the already enabled napi

Change: Fix the state validation condition

Impact: (ESX only)

Version 1.60.40 (Sep 7, 2010)
==============================
Fixes
-----
1. Problem: Possible corrupted fast-path state after nic load

Cause: The fast-path structure is not zero'd during nic load

Change: bzero the fast-path structure

Impact: Introduced in 1.60.28

2. Problem: Accessing NULL pointer when debug printing queues stats and
ooo rings are disabled

Cause: the debug print loop iterates over all rx/tx queues instead
of the strictly L2 queues. When ooo is disabled the print will
access NULL pointers

Change: Iterate over the L2 queues only (eth_queues)

Impact: Introduced in 1.60.01

3. Problem: (CQ49299) HW stuck after 8 hours of heavy LSO traffic

Cause: Firmware miscalculated SGL length of LSO packet with BDs larger
than 64K, leading to erroneous HW command

Change: (In FW 6.0.32) Fix calculation

4. Problem: Under low memory condition, on kernels below 2.6.24 and
backported GRO infrastructure, when system not able to allocate
all RSS queues, some RSS queues become unfunctional

Cause: Misplaced preprocessor directives

Change: Fix preprocessor directives

Impact: Introduced in 1.60.27

Enhancements
------------
1. Request: Use FW 6.0.33

Change: As requested

Version 1.60.39 (Sep 2, 2010)
==============================
Enhancements
------------
1. Request: (CQ49671) Add capability to build against SuSE source RPMs

Change: As requested

Version 1.60.38 (Aug 31, 2010)
==============================
Fixes
-----
1. Problem: Possible inconsistency in parity recovery flow in case of bogus
usage of bnx2x_trylock_hw_lock() function

Cause: Inconsistent error core returned (-EINVAL while function
returns 'bool')

Change: Return 'false' in case of an error

Impact: Introduced in 1.60.01

2. Problem: (CQ49649) Dual Media: No 1Gb fiber link after changing driver
speed property, when cable is connected

Cause: Link interrupt is generated from NIG attention common for both
phys on dual media board. The NIG status was set for
both PHYs while it should have been done for the copper
attention only

Change: Set NIG attention according to the active PHY

Impact: Dual media boards

Version 1.60.37 (Aug 25, 2010)
==============================
Fixes
-----
1. Problem: num_queues module parameter functionality was broken

Cause: Improper initialization of the bp->num_queues

Change: Properly initialize the bp->num_queues

Impact: Introduced in 1.60.35

2. Problem: When ALL_MULTI rx mode was requested HW was configured to the
PROMISC mode

Cause: Missing `break' in a switch-case structure

Change: Added a missing `break'

Impact: Introduced in 1.60.01

3. Problem: (CQ49328) Failed to load an 57710 interface on ESX

Cause: Initialization of a forwarding client failed

Change: Don't configure iSCSI OOO by default when running on ESX (it's
not supported on ESX at the moment)

Impact: ESX only

4. Problem: Statistics counter may display inconsistent value

Cause: Counting statistics directly into shared buffer

Change: Use a private variable to fold rx_dropped value

5. Problem: HW Statistics collection through the DMAE broken on 57712

Cause: For 57712 the DMAE command needs to include the destination
function.

Change: Adjust the DMAE command to work on 57712

Impact: Introduced in 1.60.01

Version 1.60.36 (Aug 19, 2010)
==============================
Fixes
-----
1. Problem: (CQ47494) VMs were unable to pass IPv6 traffic

Cause: Default queue rx mode was not properly configured

Change: Configure a default queue to always accept an unmatched
unicast traffic and never configure it to accept all unicast
traffic (even in a promiscuous mode). This fix will also
properly resolve a packets duplication problem

Impact: ESX only

2. Problem: (CQ49197) No link at 1Gb/2.5Gb on BCM8073 based boards

Cause: CL37 BAM was enabled on all boards while it should be
configurable

Change: Disable CL37 BAM by default

Impact: BCM8073 based boards. Introduced in 1.60.21

Version 1.60.35 (Aug 17, 2010)
==============================
Fixes
-----
1. Problem: (CQ48954) Kernel panic when system is not able to allocate
all MSIX vectors requested by driver

Cause: Numbers of queues adjustment didn't count FW+OOO channels

Change: Make the adjustment independent of active channels

Impact: Introduced in 1.60.13

Enhancements
------------
1. Request: (DCBX) Change ETS behavior when 100%-0% bandwidth allocation
is received from no ETS configuration to 99%-1% bandwidth
allocation

Change: As requested

Version 1.60.34 (Aug 12, 2010)
==============================
Fixes
-----
1. Problem: Dual Media PHY 84823 activity and front panel LED's not
functioning correctly. Also Diagnostic Mode LED's not firing
correctly

Cause: LED masks not set correctly

Change: Changed LED masks, and added LED mode for Diagnostics

Impact: Dual Media boards

2. Problem: (FCoE) (CQ49244) ABTS BA_ACC dropped due to F_CTL
(LAST_SEQ bit) verification mismatch

Cause: Detecting a protocol violation in ABTS BA_ACC frame from
target (target protocol violation)

Change: (in FW 6.0.31) No need to verify LAST_SEQ bit in F_CTL field

3. Problem: (CQ49296) - Dual media: Copper link would not come up upon
removal of fiber media when serdes priority and 1GB full is set
Cause: When Fiber link is set to 1G, its XAUI will not automaticity
power down like it does in 10G. This cause the BCM84823 to
detect false link from the BCM8727 even if Fiber is not
connected. This ends up in not linking the copper side

Change: When link is configured to 1G, power down the BCM8727 XAUI
side and when link comes up, power it up

Impact: Dual Media boards

4. Problem: (CQ49137) -Dual Media: Ethtool fail - Link_test (online) on TP
every few iterations

Cause: Link detection may take very long in case of copper, while the
wait up time was limit to 10sec only

Change: Increase link wait up time in link test to 14sec

Impact: Dual Media boards

Version 1.60.33 (Aug 11, 2010)
==============================
Fixes
-----
1. Problem: (CQ48584) Intermitted link issue and unexpected behavior using
boards with external PHYs

Cause: PHY lock indication was missing on second port, so there was no
locking between the ports. When two ports tried to read/write
from the PHY, they the instruction may collide.

Change: Set PHY lock indication of both ports

Impact: 57710/57711 on boards with external PHY; Introduced in 1.50.0

2. Problem: (CQ49219) Dual media: Copper link does not come up once
10gbaseT priority is set in driver property

Cause: Link indication from both Copper and Fiber

Change: Ignore link indication from Fiber in case Copper is selected

Impact: Dual-media boards; Introduced in 1.60.32

Version 1.60.32 (Aug 5, 2010)
==============================
Fixes
-----
1. Problem: (CQ48747) Dual media: fiber port does not link at 1gig speed

Cause: The link speed in the pass-through phy (84823) was set to 10G

Fix: Set the pass-through speed to 1G as well when fiber is set to
1G

Impact: Dual-Media boards

2. Problem: (CQ49143) Dual Media: First attempt to change from default TP
to FIBRE using ethtool does not work.

Cause: When changing port type from TP to FIBRE the command failed
since FIBRE doesn't support autoneg, yet the port type was
changed.

Fix: When ethtool command fail, do not change port type

Impact: Dual-Media boards

3. Problem: Compilation error on kernels 2.6.34 and later

Cause: netdev_name() defined by both kernel and driver

Fix: Fix compat.h for these kernels

4. Problem: 84823 PHY not showing correct Link LED's.

Cause: Incorrectly setting LED Masks

Fix: Eliminated offending branch in code

Impact: Introduced in 1.60.24

5. Problem: (CQ49137) ethtool -t test fails in dual-media boards

Cause: Link wasn't tested correctly depending on the media
configuration

Change: Test link according to media configuration

Impact: Dual-Media boards

6. Problem: (CQ49004) Dual Media: Switch show link on both media
simultaneously.

Cause: Not disabling TX on non-active port.

Change: In case link is up in non SFP+, disable the SFP+ TX laser.

Impact: Dual-Media boards

7. Problem: On BCM8727 based boards, when link speed is changed from 1G
to 10G, PCS may be halted

Cause: Restoring 10G link setting was done according to old PHY
microcode

Change: Restore default 10G link setting according to new microcode

Impact: BCM8727 based boards

Version 1.60.30 (Jul 29, 2010)
==============================
Fixes
-----
1. Problem: (CQ47855) Link test fails under Linux using ethtool

Cause: In case a MAC test followed by link test, the NIG attention
might be cleared while ISR was already triggered due to NIG
attention. This led to declaring the MAC test as failed since
there's actually no link in this case

Fix: In case NIG interrupt mask is cleared during interrupt
handling, do not execute link status update routine

2. Problem: (CQ49067) Compilation failed on kernels 2.6.23 - 2.6.27

Cause: Wrong assumption in #includes order, caused BNX2X_MULTI_QUEUE
to be defined on these kernels

Fix: Remove the assumption

Impact: Introduced in 1.60.14

Enhancements
------------
1. Request: Support HW Rx hash generation for a single queue configuration

Change: As requested

Version 1.60.29 (Jul 21, 2010)
==============================
Fixes
-----
1. Problem: (CQ48770) When working with rate-limiting in 57711/2 with jumbo
frames, the rate is half of what configured

Cause: Firmware miscalculated the amount of bytes transmitted

Fix: (In FW 6.0.30) Fixed the calculation

Impact: Introduced in 1.60.16 (FW 6.0.20)

2. Problem: FW XSTORM assert during server reboot test

Cause: There were two statistics ramrods sent with the same statistics
counter. There was a race condition in the bnx2x driver that
allowed this situation

Fix: Protect statistics ramrod sending code and statistics counter
update with the spin lock

Enhancements
------------
1. Request: Use FW 6.0.30

Change: As requested

2. Request: Rearrange LLH memory organization

Change: Allow 16 MACs in the memory; do not set FCoE MACs in LLH

Impact: Switch-Independent mode only

Version 1.60.28 (Jul 14, 2010)
==============================
Fixes
-----
1. Problem: Possible crash during load/unload of one function, if more
functions are loaded.

Cause: Statistics ramrod of one function might override data of other
functions

Fix: (In FW 6.0.29) Fixed statistics ramrod

Impact: Introduced in 1.60.07 (FW 6.0.5)

2. Problem: Port detection feature(ethtool -p) for dual-media is not
working

Cause: BCM8727 LED needs to be set via the PHY, and not the MAC

Fix: Set BCM8727 LED via PHY

Impact: Dual-Media boards

3. Problem: ethtool -s ethX speed YYY does not work properly

Cause: Forcing port configuration every call to ethtool -s

Fix: Do not change port configuration if not requested

Impact: Introduced in 1.60.27

4. Problem: Divide by 0 in driver code, after disabling coalescing via
ethtool

Cause: Conversion from usec to interrupt per sec done without check
for zero

Fix: Check for zero in conversion

Impact: Introduced in 1.60.26

5. Problem: (CQ48787) ethtool -t fails in Switch-Independent mode after
bringing up higher functions (4,5,6,7)

Cause: Improper mac placement in NIG block

Fix: Fixed address calculation

Impact: Switch-Independent mode only

Enhancements
------------
1. Request: Modify Dual-media look & feel such that ethtool gets and sets
the configuration of the active PHY only. Active PHY is the
PHY which linked up, or in case of link down, according to the
port selection

Change: As requested

2. Request: Use FW 6.0.29

Change: As requested

3. Request: Don't call for pci_disable_msix() every time bnx2x_nic_unload()
is called

Change: Move pci_enable_msi/msix() to pcidev->probe() callback

4. Request: (ESX) Call for netif_napi_add() before netdev->open()

Change: As requested. This change is relevant for all platforms

5. Request: Support for ethtool_cmd.speed_hi field

Change: As requested

Version 1.60.27 (Jul 07, 2010)
==============================
Fixes
-----
1. Problem: (CQ48202) Under low memory condition, rx stop functioning
during load/unload test

Cause: Some queue may be not fully populated, under low memory
condition, which may cause FW to drop packets for this queue

Fix: Change memory allocation scheme in order to avoid this
situation

2. Problem: Link lost every other time when driver is brought up.

Cause: When the PHY swap parameter ('nvm cfg' option 124) is set, the
PHY's swap everytime the link is brought up.

Change: Instead of storing the PHY order, we calculate it fresh
everytime.

Impact: Dual-media boards.

Enhancements
------------
1. Request: Return an error if bnx2x_set_flags() is called for unsupported
flags

Change: As requested

2. Request: Don't collect statistics if requested so according to
edebug-driver interface (edebug_driver_if field in shmem2
region)

Change: As requested

Change: As requested

Impact: Dual media boards

Version 1.60.26 (Jun 30, 2010)
==============================
Fixes
-----
1. Problem: Incorrect LED behavior on dual-media platform

Cause: The LED settings are used to control GPIO in favor of
over-current detection

Fix: On NOC (No-OverCurrent) flavor, configure the GPIOs to reflect
LED behavior rather than unnecessary over-current indication

Impact: BCM8727 based boards

2. Problem: Possible deadlock on bp->stat_sm_lock spinlock

Cause: Inappropriate locking function was used for protecting a
resource accessed by workqueue and timer:
used spin_lock()/spin_unlock() while should be
spin_lock_bh()/spi_unlock_bh()

Fix: Use an appropriate locking API: spin_lock_bh()/spin_unlokc_bh()

Impact: Introduced in 1.60.22

3. Problem: Possible crash loading cnic if iSCSI OOO has been disabled
in a bnx2x

Cause: cnic was unaware of the fact that iSCSI OOO may be disabled in
the bnx2x

Fix: Add an appropriate bit in a cnic_eth_dev->drv_state and set
it if iSCSI OOO is disabled in the bnx2x. This is done in a
bnx2x_cnic_probe2()

Impact: CNIC only

4. Problem: Interrupt coalescing was disabled in the chip

Cause: Coalescing was erroneously disabled by bnx2x by default

Fix: Properly configure coalescing

Impact: Introduced in 1.60.11

Enhancements
------------
1. Request: Fit Dual media selection to the new scheme

Change: As requested

2. Request: Enable to set the GPIO which controls the external PHY reset
(through nvm cfg 129)

Version 1.60.25 (Jun 23, 2010)
==============================
Fixes
-----
1. Problem: Link down when using specific DACs (Direct Attached Cables)

Cause: Some DAC's EEPROM do not respond at 400Khz speed

Fix: Set 2-wire transfer rate of SFP+ module EEPROM to 100Khz

Impact: BCM8727 based boards

2. Problem: (FCoE) (CQ48021) RESET_LUN operation failed due to
error detection

Cause: Detecting a protocol violation in response frame from
target (target protocol violation)

Fix: (In FW 6.0.28) Mask the error reporting

Impact: FCoE only

3. Problem: (FCoE) 10% performance degradation

Cause: Read queue used by firmware did not have enough credits

Fix: (In FW 6.0.28) Change the read queue used by firmware

Impact: Introduced in 1.60.24 (FW 6.0.27)

4. Problem: (FCoE) (CQ48403) Target does not handle incoming FCP_DATA

Cause: Increasing SEQ_CNT is not supported by target

Fix: (In FW 6.0.28) Reset the SEQ_CNT back to zero when transmitting
new FCP_DATA frame

Impact: FCoE only

5. Problem: There was a "timeout waiting for queue[0]" message in a syslog
when running self-test (ethtool -t ethX) on 57712

Cause: Unlike HC IGU won't generate an interrupt for status block
updates that have been performed while interrupts disabled thus
Tx work generated by loopback test will never be handled

Fix: Call for bnx2x_tx_int() from inside the loopback test for chips
with IGU (57712 and newer)

Impact: 57712 only

6. Problem: (CQ48284) up-down test on port 1 causes traffic to stop on
port 0

Cause: Improper cleanup of HC and IGU blocks during function init

Fix: Fix HC block cleanup, remove unnecessary IGU clean-up

Impact: Introduced in 1.60.15

Enhancements
------------
1. Request: (CQ48374) Add a module parameter to disable iSCSI OOO

Change: As requested: added a disable_iscsi_ooo module parameter, which
is present if BCM_CNIC is defined, otherwise iSCSI OOO is not
enabled anyway

2. Request: (iSCSI) Add counters for iSCSI out-of-order events

Change: As requested (counters can be read from RAM through GRC)
(In FW 6.0.28)

3. Request: Use FW 6.0.28

Change: As requested

Version 1.60.24 (Jun 16, 2010)
==============================
Fixes
-----
1. Problem: (iSCSI) (CQ42399) Unable to run I/Os greater than 1500 bytes
with initiator MTU set to 9000 and target MTU set to 1500

Cause: Timestamp option was not considered in MSS calculation

Fix: (in FW 6.0.27) Fix mss calculation when timestamp option
is present

Impact: iSCSI only

Cause: Incorrect FIN max retransmit count

Fix: (in FW 6.0.27) Fix FIN max retransmit count

Impact: iSCSI only

3. Problem: (FCoE) Address calculation of task-context in Ustorm
could be wrong

Cause: Address calculation considered an argument twice

Fix: (in FW 6.0.27) Fix calculation

4. Problem: (FCoE) Ustorm RAM read/update could be wrong during
event generation

Cause: Confusion between addresses while accessing RAM databases

Fix: (in FW 6.0.27) Use appropriate address for each specific
database

5. Problem: (FCoE) ABTS local-completion mechanism did not handled error if
error was detected on ABTS BA_ACC

Cause: Not handling error caused an assert

Fix: (in FW 6.0.27) Handle error by overwriting RX state.
Cleanup shall follow to clean the task

6. Problem: (FCoE) Writing to host memory from Tstorm could be corrupted

Cause: Using the same write VQ for Tstorm and Cstorm

Fix: (in FW 6.0.27) Using the write VQ belongs to Tstorm only

7. Problem: bnx2x wouldn't properly function with 2.6.29 kernel

Cause: bnx2x used new netdev->netdev_ops interface starting from
2.6.30 and not from 2.6.29 kernel as should be

Fix: Use new netdev_ops interface starting from 2.6.29 kernel

Impact: 2.6.29 kernel only

Enhancements
------------
1. Request: Align TCP advertised window in iSCSI (4b alignment)

Change: As requested in FW 6.0.26

2. Request: Mask protocol violations error detected by chip on HP targets

==============================
Fixes
-----
1. Problem: Avahi daemon crashed after loading bnx2x.ko on kernels newer
than 2.6.30

Cause: SAN MAC was added (dev_addr_add()) before netdev_register()
call and call_netdevice_notifiers(NETDEV_CHANGEADDR, dev) has
been called for a unregistered device

Fix: Call dev_addr_add() after netdev_register()

Impact: Introduced in 1.60.21

2. Problem: Link status notification appeared each time when DCBX
negotiation received

Cause: DCBX update handled as link update and notification printed

Fix: Remove link notification from this flow

Impact: DCBX only

3. Problem: (CQ47700) Can't get Link when forcing speed on 10/100M

Cause: When link is not set to autoneg, MDIX wasn't enabled so link
couldn't be established on direct cables

Fix: Enable MDIX when autoneg is disabled

Impact: BCM84823 based board

4. Problem: (CQ47671) "ethtool -p ethx" has no effect on the port's LED

Cause: Specific PHY requires specific phy settings

Fix: In case of copper phys, set LED registers directly in the PHY,
rather than the NIG

Impact: Copper boards

5. Problem: (iSCSI OOO) Producer of OOO Rx CQ ring was updated twice than
was expected

Cause: The mentioned producer was updated both in the
bnx2x_cnic_get_ooo_cqe() and in the bnx2x_cnic_reuse_ooo_pkt()
while is meant to be updated only in the
bnx2x_cnic_reuse_ooo_pkt()

Fix: Don't advance CQ ring producer in the bnx2x_cnic_get_ooo_cqe()

Impact: iSCSI OOO only

6. Problem: (iSCSI) UIO Client wasn't able to handle IPv6 traffic

Cause: UIO Client was not receiving multicast traffic because in
non-promiscuous mode only one Client per function will receive
multicast packets (leading RSS Client)

Fix: Configure UIO Client's to accept all multicast packets

Impact: iSCSI only

7. Problem: bnx2x would not compile on kernel 2.6.34

Cause: Improper dependency in bnx2x_compat.h

Fix: Switch on netdev_hw_addr_list_for_each during bnx2x_mc_addr()
definition

8. Problem: (CQ47854) Driver crash during FCoE test

Cause: HW assert causes driver to halt

Fix: Notify user with appropriate message without causing panic

while up/down test

Cause: Race on update of statistics' state machine

Fix: Use spinlock to protect the state machine

2. Problem: (CQ46918) Network bursts are larger than the configured
connection on FLEX 10

Cause: Inaccurate bytes calculation at rate shaping mechanism

Fix: Calculation was fixed in FW 6.0.25

3. Problem: (CQ47623,CQ46388,CQ47225,CQ47833) System hangs during
iSCSI stress traffic

Cause: Incorrect packet trimming lead to HW internal error

Fix: Fixed packet trimming on LB port in FW 6.0.25

Impact: Introduced in 1.60.10 (FW 6.0.11)

4. Problem: All BRB interrupts are masked

Cause: BRB interrupt mask is not initialized so reset value is used

Fix: Initialize interrupt mask so only parser read length errors
are masked

Impact: In scenarios where BRB interrupts occur, indicate appropriate
error information

5. Problem: (CQ47834, CQ47795, CQ47980) On low memory condition, driver
caused kernel panic in bnx2x_ilt_mem_op()

Cause: Unallocated memory access

Fix: Validate non NULL pointers before access

6. Problem: (FCoE) FCoE traffic experiences a lot of drops

Cause: Improper PFC configuration - mixed RX/TX COSes

Fix: Fixed configuration

Impact: Introduced in 1.60.21

==============================
Fixes
-----
1. Problem: (iSCSI OOO) Kernel panicked in the skb_put() when called from
bnx2x_cnic_reuse_ooo_pkt()

Cause: Wrong skb function has been used for resetting the data length
in the skb: skb_put(skb, -skb_headlen(skb))

Fix: Use the proper function: skb_trim(skb, 0)

Impact: iSCSI OOO only

2. Problem: 57710 - Load/unload stress test caused chip to hang

Cause: Disable of device in the middle of MSIX message caused deadlock
in HC block

Fix: Use PCI configuration space to avoid the deadlock

Impact: 57710 only

Cause: iSCSI mac was not written into NIG memory

Fix: Fix handling of MAC addreses in switch independent mode

Impact: switch independent mode only

4. Problem: Changing MTU when CNIC is loaded was causing CFC error

Cause: Setting CDU validation value for iSCSI L2 Client was done from
bnx2x_register_cnic(), which is not called in change MTU flow

Fix: Move setting of iSCSI L2 Client CDU validation value to
bnx2x_cnic_sp_post() right before it sends iSCSI L2 Client
SETUP ramrod

Impact: iSCSI only

5. Problem: 57710/57711/57711E: unable to load device on machine with 16
(and more) CPUs

Cause: Improper HC SB calculation

Fix: Exclude none l2 contexts from HC SB calculation

Impact: 57710/57711/57711E only; introduced on 1.60.13

Enhancements
------------
1. Request: (FCoE) Set SAN MAC before ifup event in order to allow the
bnx2fc properly configure WWN

Change: Move the dev_addr_add() for a SAN MAC to pci_dev->probe() flow
(bnx2x_init_one()) making it similar to networking MAC address
configuration (it is configured in netdev at this stage as
well). dev_addr_del() for a SAN MAC has been moved to
bnx2x_remove_one() correspondingly

Impact: FCoE only

2. Request: Lower the bnx2x skb memory footprint on ESX

Change: Limit the OOO Rx ring to 40 BDs

Impact: ESX only

Version 1.60.20 (May 18, 2010)
==============================
Fixes
-----
1. Problem: (iSCSI OOO) Call for bnx2x_cnic_reuse_ooo_pkt() was causing a
kernel panic

Cause: There was a wrong fp picked in bnx2x_cnic_reuse_ooo_pkt() (fwd
instead of ooo)

Fix: Pick the right fp

Impact: iSCSI OOO only

2. Problem: (FCoE)(CQ47674) Chip hangs during destroy FCoE connection flow

Cause: FCoE reordering mechanism was corrupted during disable
connection flow

Fix: (Fixed in FW 6.0.24) Assure not to overrun relevant context
for reordering operation

Impact: FCoE only

3. Problem: (FCoE)(CQ47644) Chip reporting an error instead of dropping
the packet

Cause: Some errors were detected before verifying FCoE delimiters

Fix: (Fixed in FW 6.0.24) Once an error detected, verify first the
FCoE delimiters before reporting an error

Impact: FCoE only

4. Problem: (iSCSI OOO) Chip hangs during out-of-order traffic

Cause: Firmware internal synchronization issue between iSCSI
and L2 flows

Fix: (Fixed in FW 6.0.24) Firmware fix

Impact: Introduced in 1.60.10 (FW 6.0.11)

Enhancements
------------
1. Request: Add BNX2X_MSG_CNIC debug level

Change: As requested

2. Request: Allow the RX rings to be initialize with a lower number of
entries (at the source code level)

Change: As requested

3. Request: Use FW 6.0.24

Change: As requested

4. Request: Enable PFC statistics in MAC

Change: As requested

Version 1.60.19 (May 12, 2010)
==============================
Fixes
-----
1. Problem: (iSCSI OOO): OOO packets were not indicated on the OOO Rx ring

Cause: There were missing OOO ring's CID and Client ID configuration
in a TSTORM

Fix: Properly configure OOO ring's CID and Client ID in the TSTORM
memory

Impact: iSCSI OOO only

2. Problem: (iSCSI OOO): CNIC SB context in internal memory was zeroed
after OOO and FWD rings' ramrods were completed

Cause: There was a call for bnx2x_init_sb() for CNIC SB in
bnx2x_register_cnic()

Fix: Remove the bnx2x_init_sb() call from bnx2x_register_cnic()

Impact: iSCSI OOO only

3. Problem: (CQ46146) "ethtool -t" fails when the speed is forced on cx4
NICs to 100/10Mb

Cause: Internal loopback test needs to conducted when speed is set
to 10G force

Fix: Set speed to 10G force during loopback test, and restore link
speed afterwards.

Impact: ethtool -t test

4. Problem: Spelling error in module parameter

Cause: "Then" used instead of "Than"

Fix: Fixed to "than"

5. Problem: (CQ47609) Link Level Pause causes link to pause after PFC
has been negotiated

Cause: Wrong MAC registers configuration

Fix: Fix configuration

Impact: 57712 only

6. Problem: Link change after PMF migration may halt the system

Cause: PHY attributes are provided to the initial PMF only

Fix: Load PHY attributes for every new function regardless of
being PMF or not.

Impact: Multi-function mode

7. Problem: (iSCSI OOO) OOO FW was not processing the incoming OOO packets

Cause: TSTORM internal RAM was not properly initialized

Fix: Properly initialize OOO producer, CID and Client ID of OOO ring
in a TSTORM internal memory

Impact: iSCSI OOO only

8. Problem: (iSCSI OOO) L2 FW was generating XSTORM
x_eth_vlan_special_check assert when trying to post packets on
a FWD ring

Cause: The running index that was posted on a VLAN field of the start
BD was starting from 1, while FW was expecting it to start from
0

Fix: Keep driver's packet producer and consumer running from 0 and
decrement a FW packet consumer during completions handling
instead

Impact: iSCSI OOO only

9. Problem: (CQ47445) The duplex mismatch does not work as expected

Cause: Duplex was set correctly in the phy, but wasn't passed to the
driver. In addition, when setting 10/100 force speed, it
actually advertised 10/100 with autoneg.

Fix: Return the correct duplex result, and when speed is set to 10/
100, set the speed actually for force 10/100

Impact: BCM84823 based boards

10. Problem: (CQ47383) It takes long time to re-establish link in when
working against some switches in force 1G mode

Cause: PHY is unable to establish good link in this mode

Fix: Enable CL37 BCM autoneg instead of working in force 1G

Impact: BCM8073 based boards

11. Problem: (CQ47436) FC setting not consistant

Cause: "ethtool -a" show flow-control autonegotiation as off when
speed is not set to autonegotiate.

Fix: Show the actual flow-control settings on "ethtool -a", but
in case the speed setting is actually force speed, this setting
will have no affect like with the BCM8727

Impact: ethtool -a

12. Problem: (CQ45632) NETDEV Watchdog message appeared and system hung

Cause: driver disables tx while carrier still on

Fix: call to netif_carrier_off() after netif_tx_disable()

Enhancements
------------

2. Problem: Loading driver on one port may cause link toggling on the
other port

Cause: PLL was initialized for both ports instead of per chip

Fix: Initialize PLL once during common init

Impact: 57712 only

3. Problem: Possible race between firmware threads when loading context
to chip

Cause: Common firmware handler which loads context for slow path
handler may override other handlers context load responses

Fix: The common handler considers it's thread
Id when waiting for the context load response

4. Problem: Loading driver on one port may cause link toggling on the
other port

Cause: Firmware generates false data digest error on incoming PDU

Fix: (Fixed in FW 6.0.22) Firmware fix

Impact: Introduced in 1.60.10 (FW 6.0.11)

5. Problem: (iSCSI) (CQ46388,CQ46608,CQ46638) Chip hangs when running

parity error

Cause: Improper handling of MSI-X enable/disable flow in parity error
case

Fix: Disable interrupts, disconnect from IRQs and disable MSI-X in
OS level in bnx2x_nic_unload() both in parity error case

2. Problem: FIP packets won't arrive to the FCoE L2 ring

Cause: Current FW still doesn't support the FIP packets filtering
according to the ETH type

Fix: Revert the previous enhancement that removed setting the "FIP
MAC" to the FCoE L2 Client

Impact: Introduced in 1.60.16

3. Problem: PCI speed is always reported as 5G (Gen2) on 57712

Cause: Wrong decoding of the PCI speed

Fix: Fixed the speed decoding

Impact: Only 57712

4. Problem: There was a possibility that packets might be transmitted on
the queue of the FCoE L2 Client before its SETUP ramrod is
completed

Cause: bp->state was set to OPEN after FUNCTION_START ramrod
(before SETUP ramrod(s) are sent)

Fix: Set bp->state=OPEN only after all Clients' SETUP ramrods complete

Impact: FCoE only, introduced in 1.60.10

5. Problem: (FCoE) Chip transmitting unwanted FCP_CONF frames

Cause: Incorrect update of the CONFQ TX producer

Fix: (Fixed in FW 6.0.21) Reset the CONFQ TX producer at the

Cause: bnx2x copied upper to lower and lower to upper

Fix: Assignment fixed

Impact: Introduced in 1.60.01

3. Problem: iSCSI L2 ring Rx side wasn't functional

Cause: iSCSI L2 Client Rx filtering configuration wasn't properly set

Fix: Properly set iSCSI L2 Client Rx filtering configuration

4. Problem: CQ047058: Link occasionally doesn't come up with 8073 based
boards

Cause: Insufficient delay during phy firmware load sequence

Fix: Increase delay during phy firmware load sequence to 120ms

Impact: BCM8073/BCM8727

5. Problem: Function unload could bypass statistic ramrod (Theoretical bug)

Cause: There was no reordering mechanism in the relevant firmware
flows

Fix: (Fixed in FW 6.0.20) Adding reordering

Impact: Introduced in 1.60.10 (FW 6.0.12)

6. Problem: (FCoE) (CQ47126, CQ47129) Miss detection of fc-crc error

Impact: Introduced in 1.60.10 (FW 6.0.11)

8. Problem: There were sporadic "timeout waiting for state X" messages in
the dmesg when loading/unloading the driver

Cause: There was a race on bp->set_mac_pending variable during
increment/decrement

Fix: Replace increment/decrement of bp->set_mac_pending to
set 1/set 0 to avoid the race

9. Problem: TSO packet was not identified is ESX environment
(as a result there were CSUM errors on wire)

Cause: Wrong condition is checked for identification of TSO packet

Fix: Fix the TSO identification condition (only check
skb_shinfo(skb)->gso_size for being not zero)

Impact: ESX and old kernels only (below 2.6.18)

10. Problem: Possible sporadic memory garbadging

Cause: Waiting for CFC_DEL ramrod completion for OOO Client was
done in polling mode while default SB interrupt was still
enabled

Fix: Always wait for CFC_DEL ramrod completion in interrupt driven
mode for all clients

Impact: Introduced in 1.60.15

Enhancements
------------
1. Request: Reuse completed Tx buffers in Rx ring from Tx DPC

Version 1.60.15 (Apr 15, 2010)
==============================
Fixes
-----
1. Problem: FCoE INIT ramrod timeout

Cause: HW wasn't producing interrupt on CNIC SB

Fix: bnx2x didn't send an ACK to IGU after establishing
OOO and FWD clients

Impact: CNIC only

2. Problem: (CQ47020) Kernel panic during cnic load

Cause: Initializing of iSCSI L2 context validation values was done
from bnx2x_cnic_probe() function, which is called both for
devices that are down and their memories are still not
allocated (including contexts)

Fix: Initialize iSCSI L2 context from bnx2x_register_cnic() which
may be called only for interfaces that are up

Impact: CNIC only

3. Problem: CFC error when FCoE INIT ramrod is sent

Cause: FCoE Init CID was not initialized

Fix: Initialize fcoe_init_cid to the correct value in
bnx2x_cnic_probe()

Impact: 57712 only

2. Problem: Link LED for 10M/100M/1000M is not functional on BCM84823 based
boards

Cause: LED functionality was controlled by 10G core all the time

Fix: When link speed is up in 10M/100M/1000M, set led control to
1G core.

Impact: BCM84823/BCM8481 based boards

3. Problem: Link doesn't come up when changed from 1G to 10G with BCM84823
based boards.

Cause: Phy wasn't initialized in this case so some parameters were not
cleared

Fix: Reset phy when any parameter is changed

Impact: Seen on BCM84823 based board, but may relate to others

4. Problem: (CQ46902) Unable to load driver on some systems

Cause: Old BIOS behaviour is not compliant with newest PCIE spec

shows incorrect value

Cause: Variable initialized to incorrect value of 2

Fix: Fixed to appropriate 0 (CEE)

2. Problem: FC behavior is changed so that setting FC to auto when speed
is force has no influence of to flow-control

Cause: Although this configuration is not so logic, many boards have
their configuration build this way so need to restore this
behavior

Fix: Change back to old behavior

Impact: Optic devices. Introduced in 1.60.11

3. Problem: When RX-polarity swap is set, traffic in 1G link doesn't pass.

Cause: RX-polarity was set on the PMA/PMD side instead of the XGXS
side

Fix: Set RX polarity on the XGXS side of the 8073

Impact: KR (BCM8073)

4. Problem: Autoneg flow-control is not seen using "ethtool -a"

Cause: Duplicating the link parameters configuration for dual-media
platform

Fix: Return the correct FC status

Impact: Introduced in 1.60.11

5. Problem: Self-test was reporting errors in an IGU block when driver was
configured to use INT#x

Cause: Driver was reading interrupt status register when IGU was
still disabled for the current PF

Fix: Connect to IRQs after HW initializing

6. Problem: Self-test was reporting errors in an IGU block when driver was
configured to use INT#x

Cause: Driver was reading interrupt status register when IGU was still
not configured to Single ISR mode

Fix: Set IGU_PF_CONF_SINGLE_ISR_EN bit together with
IGU_PF_CONF_FUNC_EN when driver is configured to Single ISR
mode (MSI or INT#x) and do not turn it off unless the driver is
configured to use MSI-X interrupt mode

Impact: 57712 only

7. Problem: When link speed is set to 1G, link comes up in 10G when
connected to device which advertise 10G.

Cause: BCM84823 always advertises 10G speed.

Fix: When speed capability doesn't include 10G, or force speed is
not set to 10G, disable 10G advertisement

Impact: BCM84823, BCM8481

8. Problem: (CQ46844, CQ46842) Driver did not work properly on machines
with large number of CPUs.

Cause: Driver was managing more resources then available in FW

Fix: Taking into account max available L2 contexts

Fix: (Fixed in FW 6.0.17) The ramrod no longer send host coalescing

Impact: Introduced in 1.60.6 (FW 6.0.3)

10. Problem: Firmware asserted when TPA is disable

Cause: Wrong logic in the assert Conditions

Fix: (Fixed in FW 6.0.17) The assert may occur only when TPA is
enabled

Impact: Introduced in 1.60.12 (FW 6.0.15)

11. Problem: VF: system crashed when VF reads client init data

Cause: Reading client init from VF memory and not from PF memory

Fix: (Fixed in FW 6.0.17) VF read the client init from PF memory

Fix: (Fixed in FW 6.0.13) Fixed confirmation request verification

Impact: Problem exists in all previous FCoE versions

12. Problem: (CQ46005) Maximum bandwidth allocation feature not working
as expected

Cause: Storm clock frequency was 500MHz instead of 550MHz - this
affects the RT clocks configuration which had a 10% deviation

Fix: (Fixed in FW 6.0.14) Firmware now use correct clock frequency
for RT configuration

Impact: Relevant only to BCM57712

13. Problem: "Pause on exhausted rings" functionality broken

Cause: Internal firmware variable was not set properly in RAM

Impact: Introduced in 1.60.10 (FW 6.0.11)

17. Problem: The firmware supported only unicast addresses that were
recognized by the LLH (limit to 16 MACs) in
switch independent mode

Cause: The search in the CAM used the function id from the LLH

Fix: (Fixed in FW 6.0.15) Unmasked the function id in searches
in the cam in switch independent mode

Impact: Introduced in 1.60.10 (FW 6.0.10)

18. Problem: (iSCSI) Firmware might spin into infinite-loop when RQ is full

Cause: Priority of Sleep when fetching new RQ producer is too high

Fix: (Fixed in FW 6.0.15) Reduce sleep priority

Impact: Introduced in 1.60.10 (FW 6.0.11)

19. Problem: (iSCSI) Saturated window was not supported in option2
TCP connect

Cause: Feature not supported

Fix: (Fixed in FW 6.0.15) Add support in firmware

7. Problem: BCM84823 Copper link doesn't come up

Cause: Starting from firmware 2.20, BCM84823 enforces the XGXS to
link first with the BCM84823 before it triggers LASI.

Fix: Set the appropriate flag for the 84823 which enforce XGXS
initialization before external link is up

Impact: BCM84823(copper)

8. Problem: CQ45718: Driver crash after driver load

Cause: Driver was sending a relatively new command to a bootcode which
doesn't support it. This command in unfamiliar with this
bootcode, and should only be sent to bootcode which support it.

Fix: Send this command only to bootcode which support it.

Impact: SFP+ only

9. Problem: Some error statistics weren't counted correctly

Cause: The statistics address was miscalculated

Fix: Fixed address calculation (in FW 6.0.11)

Impact: Introduced in 1.60.06 (FW 6.0.3)

10. Problem: iSCSI firmware broken

Cause: TCP layer interface was changed

Fix: Applied new TCP interface to iSCSI firmware (in FW 6.0.11)

Impact: Introduced in 1.60.07 (FW 6.0.4)

11. Problem: Possible permanent locking of Tx queue

Cause: There was a memory barrier missing after tx_cons update

5. Request: Use FW 6.0.9

Change: As requested

Impact: iSCSI is not functional in this version

Version 1.60.08 (Feb 18, 2010)
==============================
**** iSCSI is not functional in this version ****
Fixes
-----
1. Problem: (CQ45963,CQ45962) DCBX IOCTL shows unusual values for
admin_configuration_ets_pg, admin_pfc_bitmap

Cause: Admin section was initialized with incorrect values

Fix: Choose correct init values

2. Problem: (CQ45961,CQ45960) DCBX IOCTL shows incorrect values for
admin_dcbx_enable, dcb_enable

Cause: The parameters were ignored by driver

Fix: Add handling for the parameters

3. Problem: (CQ45763, CQ45799) On 57712 a request can be sent on a disabled
function

Cause: Request sent from timers block that scans function 6/7 when
function 2/3 scan off is set

==============================
**** iSCSI is not functional in this version ****
Fixes
-----
1. Problem: (CQ45674) Warning message was displayed when modprobe bnx2x
"bnx2x_get_hwinfo ..."

Cause: Inappropriate printing level for the message used

Fix: Set correct level

2. Problem: BCM8073 wasn't initialized during common init

Cause: In 57712, the second port is actually port0 of the second path,
and it wasn't treated like that.

Fix: Initialize port0 of both paths of BCM8073 during common init

Impact: 57712 only and KR only

3. Problem: PCIE-X link speed is not displayed correctly for 57712

Cause: Misinterpretation of link speed encoded value

Fix: Fixed for 57712

Impact: 57712 only

4. Problem: Performance drop on high-PPS scenarios with new HC code

Cause: New HC flow was overloading a HW buffer and caused back
pressure on on-chip processors

Fix: (In FW 6.0.6) Remove some of the HW buffer uses

Impact: introduced in 1.60.01 (FW 5.3.19)

5. Problem: (CQ45499) HW attention at BCM57710 stress test

Cause: New HC flow could cause HW bug by using illegal timers command

Fix: (In FW 6.0.6) Remove the use of timers command, instead use
aggregated interrupts

Impact: introduced in 1.60.01 (FW 5.3.19) BCM57710/BCM57711 only

6. Problem: Change MTU causes L4 traffic to stop

Cause: Status Block of cnic driver was not updated during nic_load

Fix: Add cnic SB update

Impact: Introduced in 1.60.01

Enhancements
------------
1. Request: Use FW 6.0.7

Change: As requested

Impact: iSCSI is not functional in this version

Version 1.60.06 (Feb 4, 2010)
==============================
**** This version requires bootcode 6.0.6 or above for BCM57712 ****

Fixes
-----
1. Problem: FCoE wasn't receiving mcast packets, including FIP packets
sent to ALL_ENODE_MACS address

Cause: There was DROP_ALL_MCAST flag set to FCoE L2 client

Fix: Set ACCEPT_MCAST flag to FCoE L2 client that will make it
receive only matched mcast packets

2. Problem: Path1 shared memory data run over Path0 configuration

Cause: The register that marks the beginning of the shared memory is
global rather than split per path

Fix: Use different registers to mark the beginning of the shared
memory per path.

Impact: 57712 only

3. Problem: bnx2x stopped receiving on the VLAN after MTU change

Cause: VLAN removal flag was not configured after reloading FW
during change MTU flow

Fix: Configure VLAN removal flag if needed after MTU change

4. Problem: drivers enter infinite loop during crash dump

Cause: lack of parentheses in loop expression

Fix: add parentheses

5. Problem: (iSCSI)(CQ45150) OIS Assert occurred after attempting to
login to iSCSI target

Cause: Firmware bug

Fix: Fixed in FW 6.0.2

6. Problem: (FCoE)(CQ44937) Data corruption after forcing FC-CRC error

Cause: Hardware bug when detecting CRC error on FCoE data placement

Fix: (Fixed in FW 6.0.3) Firmware workaround - Send 64 DMA dummy
write commands in order to prevent the false error from
appearing

7. Problem: 57712 4-port mode doesn't link up

Cause: XGXS wasn't actually configured in this mode since the
current MD_DEVAD used didn't work.

Fix: Use different MD_DEVAD when working with the E2 XGXS

Impact: 57712 only

8. Problem: 57712 4-port D2 nic test(internal loopback test) fail

Cause: Loopback was set as 10G instead of 1G loopback

Fix: When speed selection is 1G, set 1G loopback, otherwise
set 10G loopback.

Impact: 57712 only

Enhancements
-----------

Version 1.60.04 (Jan 26, 2010)
==============================

Fixes
-----
1. Problem: (CQ43831) Driver error reports while loading/unloading under
DCC traffic

Cause: A race condition between disabling the incoming traffic when
unloading and DCC enabling the link

Fix: Changed DCC enable/disable commands to use a different register
setting that will not interfere with normal unload sequence

2. Problem: Driver load under DCC traffic might fail

Cause: Lack of lock between driver load command and DCC ack command

Fix: Add mutex to protect the FW mailbox

3. Problem: ifconfig up reported error while using bootcode 6.0.1

Cause: Lack of lock between DCBX init command and response handling

Fix: Add mutex to protect the FW mailbox

4. Problem: FW asserts while unloading/loading under DCC enable/disable
commands

Cause: DCC disable command changed the driver internal state and might
overrun state changes which are initiated by the load/unload
sequence. This caused the driver to be out of sync with the FW

Fix: DCC disable/enable command uses different flag and not the
driver state

5. Problem: Error message is printed when failing to obtain MSI-X vectors

Cause: When trying to work in multi-mode and not getting enough MSI-X
vectors, the driver printed an error message indicating that
it will use a single queue

Fix: Since this is a valid condition, the print is allowed under
specific messages level only

6. Problem: port 1 of 57712 can't initialize correctly

Cause: driver accessed incorrect shmem addresses

Fix: fixed

Impact: 57712/57712E only

7. Problem: 57712 link is not up

Cause: There's difference in AER strapping between 57711 and 57712

Fix: Set the XGXS AER to the appropriate value according to the
new XGXS model

Impact: Problem exists in all previous releases

5. Problem: (iSCSI) False data digest error when data digest is splitted
into 3 parts

Cause: Firmware bug when aligning split padding

Fix: Fixed in FW 6.0.1

Impact: Problem exists in all previous releases

6. Problem: (FCoE) (CQ45025) False REC_TOV timer expiration

Cause: Timer was not reset when a task that supports REC_TOV was
replaced by task that didn't

Fix: (Fixed in FW 6.0.1) When new task begin, we set the timer if
it supports REC_TOV and reset timer if he doesn't

Impact: Problem exists in all previous releases

7. Problem: (FCoE) Connection cache was not initialized properly and
REC_TOV\E_D_TOV timers weren't disable after all functions
destroyed

Cause: Wrong calculation of number of active functions

Fix: (Fixed in FW 6.0.1) Add designated counter for number of
active functions

Impact: Problem in BCM57712 only

8. Problem: MSI-X vectors request in repeating ifup/ifdown test case
fail due to not sufficient amount of resources

Cause: MSI-X/MSI were not disabled if ifup failed due to lack of memory

Fix: Properly release allocated MSI-X/MSI vectors if ifup failed
due to lack of memory

Enhancements
-----------
1. Request: Remove GRO dependency on kernel version

Change: Replaced with dependency on NETIF_F_GRO flag

2. Request: Use FW 5.3.20.1

Change: As requested

Version 1.60.01 (Jan 12, 2010)
==============================

Fixes
-----
1. Problem: 57712 emulation failed to run in 4 domains 10G mode
(debug only)

Cause: Driver accidently accessed non-existing EMAC

Fix: Remove access to EMAC register in case of emulation

2. Problem: In dual-media, only the SFP+ module on the first phy is checked

Cause: Insufficient support in SFP+ module checking

Fix: Modify SFP+ module API verification to include parameter
indicating the exact phy.

Impact: Whenever driver send command to the bootcode, it will now also
send parameter. Bootcode will treat this parameter only when it
is relevant

3. Problem: (FCoE) Chip hangs while running normal rd/wr operations

Cause: RX Doorbell was not handled properly

Fix: (Fixed in FW 5.3.18) Handling the case where receiving false
RX doorbell

4. Problem: (FCoE) (CQ44936, CQ44937) Data corruption during
read/write/compare test

Cause: Error was not detected by FW since it was short FCP_RSP packets

Fix: (Fixed in FW 5.3.20) Checking if received the amount of data
when receiving this format of FCP_RSP

5. Problem: (FCoE) (CQ44936, CQ44937) Data corruption during
read/write/compare test

Cause: When packet with invalid CRC detected, task context isn't
reverted to previous valid state

Fix: (Fixed in FW 5.3.20) on detection of packet with invalid CRC,
task cached context isn't write back to memory

6. Problem: (iSCSI) Chip hangs when running iSCSI read traffic

Cause: Miscalculation of HW commands when SGEs are not 64-bytes
aligned

Fix: (Fixed in FW 5.3.20) Fixing FW calculation of SGE alignment
and fields in HW command

7. Problem: (FCoE) Upper layer didn't know which MAC to use during
DCBX negotiation.

Cause: Proper MAC (SAN) was not set in the netdev.

Fix: Call dev_addr_add() with the proper MAC and SAN type.

8. Problem: (FCoE) FIP packets were not ruled by the PFC FC.

Cause: FIP packets were arriving on a regular L2 client.

Fix: Set a different MAC to the FCoE L2 client.

Enhancement
-----------
1. Request: Changed the doorbell size (the stride between consecutive
doorbells' addresses) from 4K to 128

Change: As requested

2. Request: Add support for dual-media board type

Change: Redesign the CLC to be able to handle multi-phy boards.
Rename clc/CLC to elink/ELINK.
Driver is required to probe the phys on board before
initializing the link.
Specific phy access will be done using "phy" structure.
Common access will go over all phys on board and execute the
command on them.

Impact: From now on, high level driver will not be familiar with the
phys on-board. For every phy access, it is required to use the
elink API, or add new one.

3. Request: Having the ability to pass data from the Tstorm to the driver
over the SGL in fast_path_cqe (required for iSCSI Out-Of-Order)

Change: As requested (in FW 5.3.20)

Change: As requested

3. Request: Use FW 5.3.17

Change: As requested

4. Request: Enable parity errors recognition and recovery.

Change: First implementation of parity error recovery flow. Currently
only "process kill" is supported. Parity errors are currently
disabled for E1 until the proper changes are done to init
tool.

Version 1.53.13 (Nov 17, 2009)
==============================

Fixes
-----
1. Problem: Improper initialization of MF/SF causes driver to stall

Cause: Using uninitialized values of fpid

Fix: Using fpid moved to later stages after its initialization

Version 1.53.11 (Nov 11, 2009)
==============================
Fixes
-----
1. Problem: When iptable_nat module is installed on RH4, traffic halts

Cause: iptable_nat on RH4 requests for GSO without asking for csum
offload

Fix: When configuring the HW/FW to GSO, always configure csum
offload as well

2. Problem: (FCoE) Chip hanged during data placement

Cause: Thread started placing data before verifying the task type

Fix: Fixed in FW 5.3.13: verify task type is match to read in
FCP_DATA before placement

Impact: None

3. Problem: (CQ44328) (FCoE) Chip hanged after error was detected

Cause: Thread was waiting for CRC result instead
of releasing the packet

Fix: Fixed in FW 5.3.13: Release the packet if an error occurred
during data placement

Impact: None

Enhancement
-----------
1. Request: Use FW 5.3.13

Change: As requested

Impact: None

Version 1.53.10 (Nov 08, 2009)
==============================

Enhancement

1. Request: Use FW 5.3.12

Change: As requested

Impact: None

Version 1.53.9 (Oct 27, 2009)
==============================

Fixes
-----
1. Problem: ethtool -t ethX FAILED

Cause: test_registers() accessed registers without mask

Fix: Added mask for write access

Impact: None

==============================

Enhancement
-----------
1. Request: 57712 multifunction support

Change: As requested

Impact: None

Version 1.53.5 (Oct XX, 2009)
==============================

Fixes
-----
1. Problem: Failed to build bnx2x in chroot build environment

Cause: The Makefile attempted to run with -j flag to utilize all CPU
in the system and in chroot environment it resulted with "-j 0"

Fix: The Makefile should not force the -j option. Removed this
feature

Impact: Without explicitly providing the -j flag when compiling the
driver, the compilation will consume more time

Version 1.53.4 (Oct 11, 2009)
==============================

Fixes
-----
1. Problem: Priority Flow Control on BCM57711 showed low performance

Cause: Transmitted Xon PFC packet was malformed. PriorityEnableVector
field in PFC packet was set to zero instead of the relevant
priorities. This caused to remote peer to wait longer until
timers expired to Xon again

Fix: Fixed in FW 5.3.8: set properly PriorityEnableVector in Xon
PFC packet

Impact: None

2. Problem: (CQ43517) SLES11u0 iSCSI: SUT hangs when unexpected FIN packet
was received under traffic

Cause: FW erroneously increased activity counter

Fix: Fixed in FW 5.3.8: condition for activity counter increment
fixed

Impact: None

3. Problem: (CQ43517) SLES11u0 iSCSI: SUT hangs when unexpected SYN packet
was received under traffic

Cause: TCP reset initiated by FW caused endless wake ups for FW

Fix: Fixed in FW 5.3.8: changed setting of FW internal flags

Impact: None

4. Problem: iSCSI offload: Memory sanity of thread check fail during Query
ramrod

Cause: During Query ramrod, when FW prepared the context for upload
on the scratchpad, it exceeds the thread scratchpad boundary

Fix: Fixed in FW 5.3.8: use the scratchpad within the thread
boundary only

Impact: None

5. Problem: iSCSI offload: TCP Close failed

Cause: Bug in byte credit update during termination

Fix: Fixed in FW 5.3.8

Impact: None

6. Problem: FCoE INIT ramrod was never completed

Cause: Reading from inappropriate VQ in Tstorm

Fix: Fixed in FW 5.3.8: reading from to the correct VQ

Impact: None

Enhancement
-----------
1. Request: BCM577xx support for FW 5.3.8

Change: As requested

Impact: None

2. Request: Adding support broadcast and multicast received packets in
L2 switch independant mode

Change: In FW 5.3.8 as requested

Impact: None

Version 1.53.3 (Oct xx, 2009)
==============================

Fixes
-----
1. Problem: Only Tx queue 0 was used in default configuration on
kernel 2.6.30 and above

Cause: bnx2x_select_queue() was returning 0 by default

Fix: Make bnx2x_select_queue() return stack tx_hash() by default

Impact: None

Enhancement
-----------
1. Request: Add a separate L2 ring for FCoE L2 traffic

Change: As requested

Impact: None

Version 1.53.2 (Oct 8, 2009)
==============================

Fixes
-----
1. Problem: 57712 failed to receive data from network

Cause: Incorrect MAC type selected during initialization

Fix: MAC initializaton fixed

Impact: None

2. Problem: 57712 failed to bring up interface

Cause: Unhandled attention interrupt caused processor to stall

Fix: Added handling for new attentions

Impact: None

Version 1.53.1 (Oct 5, 2009)
==============================

Enhancement
-----------
1. Request: 57712 support for FW 5.3.7

Change: As requested

Impact: None

Version 1.53.xx (Sep xx, 2009)
==============================

Enhancement
-----------
1. Request: When PFC is enabled, set BigMAC to relay control packets to the
system as well, and enable BigMAC to react on received Pause
packets

Change: As requested

Impact: None

Version 1.53.0a (Oct 1, 2009)
==============================

Enhancements
------------
1. Request: Use FW 5.3.7

Change: As requested

Impact: None

2. Request: Add support for BCM57712 (by compilation flag)

Change: As requested

Impact: None

Version 1.51.0a (Sep 14, 2009)
==============================

Fixes
-----
1. Problem: Enabling fairness algorithm in the middle of the run causes
the function to stop transmitting.

Cause: The fairness credit is not initialized in this case.

Fix: Change the fairness credit init value.

Impact: None.

2. Problem: (CQ42873) No traffic when number of receive buffers is configured
to 50 (the minimum) in the advanced properties page.

Cause: Firmware is always saving a CQE for each TPA aggregation.
So in case less then 75 CQEs are on the ring, the firmware
starts dropping packets.

Fix: Check if TPA is enabled before deciding if to drop packet.
If TPA is disabled save only 11 CQEs instead of 75.

Impact: None.

Enhancements
------------
1. Request: Use FW 5.3.4

Change: As requested

Impact: None

Version 1.51.x (Aug xx, 2009)
=============================

Fixes
-----
1. Problem: Link is down with BCM8481 when connected to 1G device after
it was connected to 100M device

Cause: When link type changes from SGMII to GMII/XGMII, the SGMII
configuration wasn't removed

Fix: Remove SGMII configuration in non-SGMII link type

Impact: None

2. Problem: BCM8481 link is not able to link up after cable plug out/in

Cause: New BCM8481 image required new configurtion of the LED4 signal
which generate the interrupt

Fix: Detect link down using the LED4 signal rathen than the BCM8481
registers

Impact: None

3. Problem: Link is down with BCM8481 when connected to 1G device after
it was connected to 100M device

Cause: When link type changes from SGMII to GMII/XGMII, the SGMII
configuration wasn't removed

Fix: Remove SGMII configuration in non-SGMII link type

Impact: None

4. Problem: BCM8481 link is not able to link up after cable plug out/in

Cause: New BCM8481 image required new configuration of the LED4 signal
which generate the interrupt

Fix: Detect link down using the LED4 signal rather than the BCM8481
registers

Impact: None

5. Problem: Driver might read corrupted data from shared memory in case
bootcode is missing

Cause: Some pieces of code are not protected in case bootcode is
missing

Fix: Add additional protection in case bootcode is missing

Impact: None

Enhancements
------------
1. Request: When PFC enabled, pass pause frames towards the NIG

Change: As requested

Impact: None

2. Request: Improve FP performance

Change: Remove writing ACK to USTORM from Tx flow and to CSTORM from
Rx

Impact: None

3. Request: Handle fan failure for BCM8481 PHY

Change: As requested

Impact: None

4. Request: Once PFC is selected along with emac, it is required to set
BIT 3, KEEP_MAC_CONTROL, at emac register rx_mode.
Setting this bit causes MAC control frames (except for pause
frames) to be passed on for processing. This setting has no
affect on the operation of the pause frames.
This bit affects all packets regardless of RX Parser packet
sorting logic.

Change: As requested

Impact: None

5. Request: Use FW 5.1.23.1

Change: As requested

Impact: None

6. Request: Support kernel 2.6.31 (RC2)

Change: Use DMA_MAP macros and .ndo_select_queue

10. Request: Enhance bnx2x_panic_dump() - print SB data

Change: As requested

Impact: None

Version 1.52.2 (Aug 18, 2009)
=============================
Fixes
-----
1. Problem: (CQ42998) 57711E PF on OS linked even after unassigning
network in VC

Cause: ethtool reports the physical link status instead of PF OS
link status

Fix: bnx2x_get_link() returns no link if driver is not in open
state

Impact: None

2. Problem: ethtool displays 57711E PF link speed as 0 in certain
scenario

Cause: VC assigned network and max bandwidth were not refreshed
during driver load

Fix: Refresh the VC assigned network and max bandwidth during
driver load

Impact: None

3. Problem: syslog and kernel logs always report 57711E PF speed
as 10000 Mbps

Cause: bnx2x_link_report() reports the actual physical link speed
instead of the max bandwidth assigned to the PF

Fix: Report the max bandwidth assigned to the PF

Impact: None

4. Problem: In some cases FW does not respond in time to driver requests
and thus driver load fails

Cause: For certain PHYs, FW might need some more time before
responding to driver request

Fix: Increase the timeout up to 5 sec

Impact: None

Enhancements
------------
1. Request: Set interrupt coalescing granularity to 4us instead of 12us

Change: As requested

Impact: None

2. Request: Change default interrupt coalescing numbers to supported
numbers

Change: Since the interrupt coalescing granularity is 4us, a value of
25 is actually configured as 24 to the HW

Impact: None

3. Request: Fix bnx2x_fw_dump() to compute trace start address based on
shmem offset

Change: As requested

Impact: None

Version 1.52.1 (Aug 12, 2009)
=============================
-- Upstream Version --
Fixes
-----
1. Problem: Link is down with BCM8481 when connected to 1G device after
it was connected to 100M device

Cause: When link type changes from SGMII to GMII/XGMII, the SGMII
configuration wasn't removed

Fix: Remove SGMII configuration in non-SGMII link type

Impact: None

2. Problem: BCM8481 link is down after cable plug out/in

Cause: New BCM8481 image required new configuration of the LED4 signal
which generate the interrupt

Fix: Detect link down using the LED4 signal rather than the BCM8481
registers

Impact: None

3. Problem: (CQ35477) Incorrect display of External Phy Firmware Version
for Everest XFP board.

Cause: External Phy Firmware Version for BCM8705 PHY used to display
0000:0000

Fix: Change not to display PHY FW version

Impact: None

4. Problem: In BCM8727, spirom was loaded first on slave port, rather than
on the master port. This may lead to xaui pll issue.

Cause: Port-Swap wasn't considered when loading spirom to the BCM8727,
hence first the slave port was loaded with the spirom.

Fix: First load the SPIROM to the master port.

Impact: None

5. Problem: Possible FW assert in driver unload/load test case

Cause: Possible race on statistics state machine state change

Fix: Added a write barrier to ensure that the state change is
committed

Impact: None

Enhancements
------------
1. Request: In promiscuous mode, pass management traffic to the host

Change: As Requested

Impact: None

2. Request: PCI drivers that implement the struct pci_error_handlers'
error_detected callback should return PCI_ERS_RESULT_DISCONNECT
if the state passed in is pci_channel_io_perm_failure

Change: As Requested

Impact: None

3. Request: (CQ41112) PHY LED Programming for BCM8481 PHY

Change: As requested

Impact: None

4. Request: (CQ41067) Add support for CL73 on XAUI

Change: As requested

Impact: None

Version 1.52.0 (Jul 28, 2009)
=============================

Fixes
-----
1. Problem: Redundant settings of vlan_features at set_tso

Cause: There is no need to change vlan_features at set_tso since this
field is a capability field and not current settings

Fix: Remove redundant code

Impact: None

2. Problem: (CQ42550) No host traffic when NCSI is enabled on some systems

Cause: The driver did not set the required filtering flags and
received only traffic which was not intended for the BMC - on
some systems, this is not enough and the driver should enable
its own masking

Fix: Setup the driver mask to receive traffic even when NCSI is
enabled

Impact: None

Version 1.50.13 (Jul 22, 2009)
==============================

Enhancements
------------
1. Request: Update to FW 5.0.21

Change: As requested

Impact: None

Version 1.50.12 (Jul 16, 2009)
==============================

Fixes
-----
1. Problem: In some TPA aggregation cases, might go into TCP slow-start
instead of fast-retransmit

Cause: When TPA is used, pure ACK on open aggregation was aggregated

Fix: (FW 5.0.20) Do not aggregate pure ACK packets in TPA

Impact: None

Version 1.50.11 (Jul 7, 2009)
=============================

Fixes
-----
1. Problem: Setting rx-usecs to the value less than 12 causes the
traffic to stop

Cause: Did not disable HC coalescing when set the coalescing timeout
to zero (coalescing timeouts are multiples of 12us)

Fix: Disable HC coalescing, when timeout is set to the zero

Impact: None

2. Problem: Packet descriptors in NIG might get out of sync if management
egress traffic is pass through during self test

Cause: During loopback test management egress traffic might be routed
to the host and will not be cleared when exiting the diag mode

Fix: Disable management egress traffic when driver is in diag mode

Impact: None

Version 1.50.10 (Jul 1, 2009)
=============================

Fixes
-----
1. Problem: (CQ42298) Management traffic does not resume after self test

Cause: Writing to the egress management FIFO during the memory test
interpreted as a start of a management packet and cause the
FIFO not to be empty

Fix: Remove the write to the egress management FIFO from the self
test

Impact: None

2. Problem: Link up time takes too long with BCM8727 based NICs

Cause: EDC mode is not set automatically

Fix: Set EDC mode manually according to the SFP+ module type
detected (Passive DAC / Active DAC / LC-LRM / LC-SR / LC-LR)

Impact: None

3. Problem: (CQ41567) In BCM8727 based NICs, when SFP+ module is not
plugged, there is continuous messages of Link Down

Cause: The EDC tries to process the Rx data/noise because its OPRXLOS
input signal is false (low), indicating an Rx signal is
present.

Fix: Perform 'Or' of the Active Module Absent Level with the Active
Laser Loss of Light Level. This way we tell the EDC not
process Rx data/noise when the module is not present.

Impact: None

Version 1.50.9 (Jun 25, 2009)
=============================

Fixes
-----
1. Problem: Low throughput when using VLAN on kernel 2.6.26 or above

Cause: New VLAN_features field in struct net_device was not
initialized hence no offload capabilities were available with
VLAN

Fix: Initialize VLAN_features field in struct net_device

Impact: None

2. Problem: No event log in case fan failure occured prior to loading the
driver

Cause: The event was not detected since it was already set when the
driver was loaded

Fix: Check for the event on load time

Impact: None

3. Problem: Loopback test in self test might fail in case NCSI is enabled

Cause: NCSI egress traffic is received instead of the loopback test
packets

Fix: Disable NCSI egress traffic during loopback test

Impact: None

4. Problem: ethtool reports link up when the device is down

Cause: Bug in ethtool_op_get_link()

Fix: Use bnx2x_get_link() instead

Impact: None

5. Problem: 57711E WoL does not work if only one function per port was
active prior to shutdown

Cause: WoL is configured to work in SF mode

Fix: Set the chip back to SF mode (so WoL will work) even if only
one function was loaded per port in MF mode

Impact: None

Version 1.50.8 (Jun 8, 2009)
============================

Fixes
-----
1. Problem: When running many TCP connections (>200) on both ports, some
connections hangs

Cause: When all TPA aggregations are occupied, FW can override the RX
CQE consumer of the other port

Fix: Fix in FW 5.0.18: reload the RX CQE consumer from RAM after TPA
handler breaks to sleep

Impact: None

2. Problem: CL73 enhancement causes link down

Cause: Unknown

Fix: Revert CL73 enhancement until problem resolved

Impact: None

Version 1.50.7 (Jun 4, 2009)
============================

Fixes
-----
1. Problem: (CQ41533) Unapproved modules behavior is not enforced according
to nvram configuration

Cause: In case the module was not approved, the function quit before
enabling the Tx laser - so even when set to warning, there was
no link. When set to power off the module, there was continues
false indication of over current when the module was extracted

Fix: When set to warning - enable the module. Validate that the
module is present before checking for over current indication

Impact: None

2. Problem: The coalescing timeout value displayed by `ethtool' is
different for the one used by the FW

Cause: The limitation for coalescing timeout values in driver's
`ethtool -C' callback was wrong

Fix: Fix the limitation for coalescing timeout in `ethtool -C'
callback

Impact: None

Enhancements
------------
1. Request: Reduce the number of cache misses in a fast path

Change: Avoid extra cache miss by updating `trans_start' from inside
start_xmit() as long as it's done by the core network layer
starting from kernel 2.6.31

Impact: None

2. Request: (CQ41067) Add 5771x CL73 support

Change: As requested

Impact: Everest is now able to link with devices which operate in CL73
alone / CL37 alone / or both

3. Request: Make 8727 over-current behavior code more efficient

Change: As requested

Impact: None

Version 1.50.6 (Jun 1, 2009)
============================

Fixes
-----
1. Problem: In 8727, after power-fault occurred and the driver is
unloaded and then reloaded, the interrupt is not cleared

Cause: In this scenario, the mod_abs mode remain in "wait for
module plugged in", so interrupt was not cleared

Fix: Set module_absent to wait for module absent scenario

Impact: None

2. Problem: There is no need to read the warning string for un approved
modules from the FW/nvram

Cause: This is over design that cause unnecessary overhead - a
constant string can be used

Fix: Use constant warning string instead of receiving it from
FW/nvram

Impact: Warning message is not to be used in the modules nvram file

3. Problem: High CPU usage in bnx2x_free_tx_pkt()

Cause: prefetch(skb_shinfo(skb)) implied immediate cache miss when
NET_SKBUFF_DATA_USES_OFFSET is enabled

Fix: Replaced prefetch(skb_shinfo(skb)) by prefetch(&skb->end).
This would prefetch only the first one from two cache misses
needed for reading of skb_shinfo(skb)->nr_frags, which is
needed by dev_kfree_skb(skb), but it will do it in a
background avoiding an immediate CPU stall

Impact: None

Enhancements
------------
1. Request: Add support for BCM8727 without over current detection
(BCM8727_NOC)

Change: As requested

Impact: None

Version 1.50.5 (May 26, 2009)
=============================

Fixes
-----
1. Problem: (CQ38975) Failed to setup leading connection after
a lot of iterations of "down-up" test. Workaround for CQ37893
(Use INTx mode when MSI-X fails due to memory allocation
failure) was broken

Cause: bnx2x_set_int_mode() wasn't returning a status, thus there
was no way to catch a mentioned above memory allocation
failure

Fix: Return a status from bnx2x_set_int_mode()

Impact: None

2. Problem: (CQ41349) Linux panic when disabling RX chksum and running RX
traffic

Cause: TPA enabled option was not controlled per function/queue level

Fix: FW fix in version 5.0.16: TPA enabled is now controlled per
function/queue level

Impact: None

3. Problem: (CQ41434) ethtool -S was printing junk on kernels with
RSS support

Cause: There was a bug in function returning number of lines in
device statistics bnx2x_get_stats_count - it was returning
more than there actually were)

Fix: Make bnx2x_get_stats_count return the correct number

Impact: None

Enhancements
------------
1. Request: Support approved module list and warn if the module is not on
the list

Change: This feature requires bootcode 5.0.6 or later and a valid
optic modules image on the nvram. The feature is controlled by
nvram option 81

Impact: None

2. Request: Allow enabling and disabling the fan failure mechanism for
different PHY types

Change: Determine if fan failure enforcement is required according to
nvram configuration. The configuration can be auto enforcement
according to the PHY type, disabled or enabled

Impact: None

3. Request: Support firmware flow control when consuming SGEs

Change: FW change in FW 5.0.16: Added check for Flow control when
consuming SGEs from host

Impact: None

4. Request: Advertise driver DCC capabilities

Change: As requested

Impact: None

Version 1.50.4 (May 18, 2009)
=============================

Fixes
-----
1. Problem: (CQ40938, CQ40937, CQ40911, CQ40992)
LSO test failure

Cause: LSO packets with BDs that point to buffers that are less than
MSS size caused the firmware to send illegal bytes within the
same LSO packet

Fix: FW fix in version 5.0.14

Impact: Regression introduced in v1.50.2

2. Problem: (CQ41198) modprobe generate error on RH4.6 or 4.7 which will
cause kernel panic

Cause: pci_register_driver() returns count and not errno

Fix: Ignore the return code from pci_register_driver() in kernels
below 2.6.10

Impact: None

3. Problem: (CQ38975,CQ38925) Failed to setup leading connection after
a lot of iterations of "down-up" test

Cause: There were a few memory barriers missing

Fix: Add missing memory barriers

Impact: None

Enhancements
------------
1. Request: Reduce the time spent in skb_release_data()

Change: Add prefetch(&skb->end) before calling dev_kfree_skb in order
to bring in the cache line that skb_release_data() will
eventually need (based on the bnx2 patch proposed by
Eric Dumazet)

Impact: None

2. Request: (CQ33228) Add required IOCTLs to support PHY FW upgrade

Change: Add 3 magic numbers to the ethtool -E (eeprom) command to
support PHY FW upgrade init, PHY FW upgrade complete, and PHY
re-init after upgrade
Add CL45 MDIO IOCTL support

Impact: None

3. Request: Add support for BCM8481 SPI-ROM upgrade

Change: As requested

Impact: None

Version 1.50.3 (May 14, 2009)
=============================

Fixes
-----
1. Problem: (CQ40848,CQ40835) System breaks due to a firmware assert

Cause: Firmware asserted when PCI read latency for RX BD ring was
longer then 20usec

Fix: FW fix in version 5.0.12: Replace the workaround by a flow
which polls on the RX BD ring every 4usec

Impact: None

2. Problem: (CQ36705) Performance on 57711/57711E is lower when flow
control is enabled than when flow control is disabled

Cause: L2 firmware flow control was enabled for 57711/57711E and
caused performance decrease

Fix: Disable L2 firmware flow control by default (add new module
parameter to enable it)

Impact: None

3. Problem: Workqueue might not be freed if driver fail to register

Cause: Workqueue is not freed if driver fail to register

Fix: Free workqueue when driver fail to register

Impact: None

4. Problem: Negative number of received packages might be returned in
STOP_ON_ERROR debug mode

Cause: Negative errno is returned in STOP_ON_ERROR debug mode

Fix: Do not return negative number of received packages

Impact: None

5. Problem: Fan failure on BCM8727 was not supported on port 1

Cause: The fan failure assertion was tied only to port 0

Fix: The fan failure assertion is tied to port 1 also

Impact: None

6. Problem: BCM8727 shows link up while RX is disabled

Cause: When module-compliance enforcement is enabled,
and non-compliant module is detected, then the driver
disables the TX-Laser for the phy, yet the link keeps
showing link up.

Fix: When link is changing, in case the TX-laser is off,
indicate that the link is down although the phy detects
RX link up.

Impact: None

7. Problem: (CQ41000) Could miss link up event in BCM8727 right after
optic module insertion

Cause: At the time that SFP+ module plugged-in was triggered,
driver enabled the module while ignoring link change

Fix: Check for link changes during module plugged in/out

Impact: None

8. Problem: BCM8727 doesn't link in 10G after changing from 1G

Cause: 10G default configuration was overwritten after setting 1G
configuration. Since the phy is not reset, the configuration
for 10G doesn't go back to default after link speed change

Fix: When setting 10G, enforce 10G configuration, and not relay
on the default configuration.

Impact: None

9. Problem: (CQ40840) BCM57710 didn't receive multicast packets

Cause: BCM57710 was unable to receive multicast packets. This BUG
was introduced with transition to the new Rx HSI. It's unlikely
that this failure is SuSE 11 specific

Fix: Fix BCM57710 specific multicast configuration code

Impact: None

Enhancements
------------
1. Request: Add dropless_fc module parameter to send pause frames in
case where one of the host buffers (when in RSS mode) are
exhausted

Change: As requested

Impact: None

Version 1.50.2 (May 05, 2009)
=============================

Fixes
-----
1. Problem: (CQ40300) XFP adapter shows link up in network properties
with no cable

Cause: Link status register was updated long after interrupt was
triggered

Fix: Check that RX PMD Loss of Sync bit is cleared and RX PMD Sync
Acquired bit is set to detect link

Impact: None

2. Problem: When Over-Current state is established, LASI interrupts are
not cleared

Cause: In this scenario, the module is powered-off so OPTXFLT/OPRXLOS
indications are set. This cause a fixed RX_ALARM indication
which cannot be turned off

Fix: When Over-current condition is detected, set RX_ALARM to
detect only module-absent events, so when a new module is
plugged in, it will be detected and then RX_ALARM will be set
to detect link as well

Impact: None

Enhancements
------------
1. Request: Improve Tx packet rate

Change: FW 5.0.10

Impact: None

2. Request: Add support for future chip revisions

Change: From now on bnx2x_main.c doesn't include huge X_init_values.h
files. Instead X_init_values.h were transformed to
X_init_values.c, which also include internal pointers
initialization function for the appropriate chip revision

Impact: None

3. Request: Add additional support for BCM8727

Change: Add support module detection, over-current detection and
SFP+ EEPROM access

Impact: None

4. Request: Add fan-failure check for BCM8727

Change: As requested

Impact: None

Version 1.50.1 (April 27, 2009)
===============================

Fixes
-----
1. Problem: (CQ39681) Dtape test fails on Dell TL2000 media changer device

Cause: Misalignment between driver and firmware

Fix: FW fix in version 5.0.8

Impact: None

2. Problem: When several protocols work together, interrupt rate is the
sum of all protocol rates, instead of the maximum between them

Cause: State machines in host coalescing code were independent
and generated interrupts on their will

Fix: FW fix in version 5.0.8: Add dependency between the states
machine - when an interrupt
is generated then all state machines of this status block
are handled as expired, resulting with lower interrupt rate

Impact: None

3. Problem: Bootcode unable to set phy configuration

Cause: When driver is loaded, it sets Serdes to work in CL45 while
the bootcode is using CL22 for phy access, so when driver
is unloaded, bootcode unable to access the phy.

Fix: When driver is loaded set Serdes mode to CL22 only when
1G-switch is set. This shall solve the issue for older
bootcodes, and will be fixed in newer bootcodes

Impact: None

4. Problem: BCM8481 is not able to link up in legacy speeds

Cause: Setting legacy speeds requires additional phy configuration,
and speed analysis

Fix: Enable legacy speeds for this phy

Impact: None

5. Problem: (CQ40392) Build for SLES11 do not autoload on reboot

Cause: SLES11 disables modules whose source is not maintained in the
kernel.org source tree

Fix: Provide "supported: external" modules for SLES11

Impact: None

6. Problem: BCM8481 is not able to link with 10/100 switch

Cause: XGXS was initializaed to work in none-SGMII mode

Fix: Set XGXS to work in SGMII mode if link speed is slower the 1G

Impact: None

7. Problem: Potential error on unload

Cause: The ILT could have been freed while a timer scan is in progress

Fix: Make sure that the timer scan is done before freeing the ILT

Impact: None

Enhancements
------------
1. Request: Improve Tx latency

Change: Removed taking tx_lock in Tx interrupt flow. This also
voided a need for tx_xon_tasklet - Tx is moved to XON state
directly from bnx2x_tx_int

Impact: None

2. Request: Add support for new BMAC HW block for new chip types

Change: When accessing the new BMAC, use the new registers.
No need to initialize the PBF HW block credits since
flow-control is always enable in that block.

Impact: None

3. Request: Enable support for other chips in more general way.

Change: Split init values and FW into 2 different files. Work
against pointers in bnx2x struct instead of global arrays.

Impact: None

4. Request: Add initial support for BCM8727

Change: Add support for the new dual-port SFP+ phy

Impact: None

5. Request: In BigMac2, when PFC enabled, pass pause frames towards the NIG

Change: Set the appropriate bit in the bigmac control register

Impact: None

6. Request: Improve Rx packet rate

Change: FW 5.0.8

Impact: None

Version 1.50.0 (April 02, 2009)
===============================

Fixes
-----
1. Problem: Rx was getting stuck on ia64 platform when system page size
was configured to be 64KB on the kernels 2.6.27 and later

Cause: The implementation on PAGE_ALIGN macro has been changed,
which caused downcast in some places in the code and as a
result improper HW configuration

Fix: Add a proper casting for the argument of SGE_PAGE_ALIGN macro

Impact: None

2. Problem: (CQ39552) Link LED is turned OFF while running external
loopback test

Cause: When using phy loopback, the link doesn't actually comes up
since there's no link partner

Fix: Set link led up on loopback test

3. Problem: BCM8481 is not able to link up in 10/100/1000 Mbps

Cause: No 10/100/1000 link signal is connected from the BCM8481 to the
Everest

Fix: BCM8481 will connect LED4 signal to the Everest LASI signal.
The Everest will use the NIG latching mechanism which allows to
catch a link event even if the link toggles fast

4. Problem: SFP+ (BCM8726) boards do not use flow-control

Cause: Flow control wasn't set for BCM8726

Fix: Set flow control according to configuration in BCM8726

Impact: None

5. Problem: Flow-control in MF mode should behave like in SF mode

Cause: Old restriction which is not necessary

Fix: Remove special flow-control configuration in MF mode

Impact: None

6. Problem: CNIC sanity tests fails

Cause: When changing to new dynamic HC code, no RAM line was allocated
to default SB so there was a memory corruption

Fix: FW fix in version 5.0.3: Add RAM line for default SB to dynamic
HC array

Impact: None

7. Problem: (CQ39503) Transmission stops for 5 second

Cause: Confusion in scaling of the receive window of the remote.
Sometimes it is taken "as is" as a number of bytes, without
scaling

Fix: FW fix in version 5.0.3: Scaling added in 3 places in the code

Impact: None

8. Problem: Low performance on Tx side in UDP test with small packets

Cause: Extra memory barrier in Tx flow

Fix: Replace mb() to wmb()

Impact: None

Enhancements
------------
1. Request: Improve FW performance

Change: HC coalescing has been moved from USTORM to CSTORM.
TSTORM performance has been improved. FW 5.0.3

Impact: None

2. Request: Add support for DCC

Change: As requested

Impact: None

3. Request: Improve performance

Change: Connect Tx and Rx to different interrupt vectors

Impact: None

4. Request: Add module parameter controlling number of Rx and Tx queues

Change: As requested. Number of Tx queues must be not more than
number of Rx queues

Impact: None

5. Request: Add "per function" statistics support for NCSI management

Change: As requested

Impact: None

Version 1.48.106 (Mar 04, 2009)
===============================

Fixes
-----
1. Problem: (CQ38925) Unload/Load with netperf TCP traffic test
eventually caused a SETUP ramrod failure

Cause: ISR discarded a SP interrupt due to weak synchronization of
atomic variable that disables interrupt handling (intr_sem)

Fix: Add write memory barriers where intr_sem is updated

Impact: None

2. Problem: Possible problem in pram initialization

Cause: There was a bug in init code generation script

Fix: Fix the pram initialization

Impact: None

Version 1.48.105 (Mar 02, 2009)
===============================
-- Upstream Version --
Fixes
-----
1. Problem: Unload/Load test under traffic caused kernel panic in
skb allocation/freeing functions

Cause: Previously added patch (enhancement 6 in release 1.48.100)
broke proper usage of net_device object

Fix: Remove the mentioned patch

Impact: None

Version 1.48.104 (Mar 01, 2009)
===============================

Fixes
-----
1. Problem: New phy version (P14) of the BCM8726 unable to link up

Cause: The new phy version doesn't behave exactly like its
previous version (P13), hence requires some adjustments

Fix: 1. Microcode download requires write of another register
2. Read from "Limiting/LRM mode" register before setting
Limiting mode

Impact: No impact on P13

Enhancements
------------
1. Request: Add limited (online) GRC dump using ethtool -d command

Change: As Requested

Impact: None

Version 1.48.103 (Feb 19, 2009)
===============================

Fixes
-----
1. Problem: "ext_phy_fw version" command for BCM8705 shows invalid number

Cause: BCM8705 has no microcode

Fix: Set BCM8705 version to 0

Impact: None

2. Problem: Potential problem in BCM8726 bit stretching work-around

Cause: When module detection option is disabled, module should be
transmitting regardless of invalid read from EEPROM

Fix: Ignore error code when setting limiting mode

Impact: None

3. Problem: (CQ38925, CQ38975) "Wait Ramrod" error while running
load/unload stress w/ traffic

Cause: Tx wasn't properly disabled in the 'close' flow

Fix: Properly disable Tx during 'close' flow

Impact: None

Enhancements
------------
1. Request: Use DMAE to zero the FW internal memory before loading the FW

Change: As Requested

Impact: None

2. Request: Remove "budgeting" in bnx2x_tx_int

Change: As Requested

Impact: None

3. Request: By default, multi_mode is disabled for old NAPI kernels
(up to 2.6.24)

Change: As Requested

Impact: None

Version 1.48.102 (Feb 12, 2009)
===============================
-- Upstream Version --
Fixes
-----
1. Problem: FW stats counters might not be updated when running heavy
stress test

Cause: Sending FW stats ramrod query depends on stats_pending flag.
This flag might not be cleared by sp_task() under heavy stress.
Thus, next FW stats ramrod query will not be send

Fix: Clear stats_pending flag at the end of storm_stats_update()

Impact: None

Version 1.48.101 (Feb 09, 2009)
===============================

Fixes
-----
1. Problem: Compilation is broken on kernels >= 2.6.24

Cause: FW constant rename was not updated in latest drop

Fix: Fix constant name

Impact: None

Version 1.48.100 (Feb 09, 2009)
===============================

Fixes
-----
1. Problem: "ext_phy_fw version" command for BCM8706 sometimes shows
invalid version number

Cause: The version number is read during init phase. Reading the
BCM8706 version during init phase is done premature

Fix: During init phase of the BCM8706, wait until the firmware
is loaded completely before reading the version number

Impact: None

2. Problem: When setting pre-emphasis values for external phys, the
XGXS is also set

Cause: In external-phy boards, when pre-emphasis values were set in
the nvram, both the external phy and the XGXS pre-emphasis
values were set, while the values fit the external phy only

Fix: Set pre-emphasis values in XGXS only for direct type boards

Impact: None

3. Problem: (CQ37809) loopback test failure

Cause: The link was initialized for real work mode and then
re-init to loopback mode. During that time, incoming packets
might be queued in the rx ring in front of the loopback packet

Fix: Always initialize the link to loopback mode if load_mode is
LOAD_DIAG

Impact: None

4. Problem: Possible false error in the idle check section of the
self test regarding the CFC_REG_ACTIVITY_COUNTER register

Cause: The test was designed to check halted system (after fatal
error) and thus assumed that the chip is idle

Fix: Change the test to "info" debug print

Impact: None

5. Problem: (CQ39439) mf_cfg function disabled error message displayed

Cause: Putting the driver into disabled mode was considered an error

Fix: Change the printed message from error to a notification

Impact: None

6. Problem: (CQ38925, CQ37645) ifconfig ethX down up may cause a wrong
MSI configuration, which will prevent MSI interrupts to arrive

Cause: Chip reset function cleared "MSI reconfigure enable" bit

Fix: Don't clear the "MSI reconfigure enable" bit

Impact: None

7. Problem: Uninitialized HW blocks

Cause: XCM and BRB1 port init part were missing

Fix: Add XCM and BRB1 port init part

Impact: None

8. Problem: Constant pause is sent to the network if pause is enabled and
TPA is disabled

Cause: Wrong thresholds were configured

Fix: Set the thresholds to 0 if TPA is disabled

Impact: None

9. Problem: Unloading UNDI by the driver in E1HMF mode might disable
interrupts of the wrong function

Cause: HC regs are splited by 4

Fix: Pritend to write as function 0 when writing to HC regs

Impact: None

10. Problem: BCM8726 MDIO access is not locked as it should be

Cause: MDC/MDIO access to BCM8726 is done via single EMAC, hence
all MDC/MDIO access to this phy needs to be locked, like
BCM8072 and BCM8073

Fix: Lock the hardware using MDIO_RESOURCE when accessing the
BCM8726 phy via MDIO

Impact: None

Enhancements
------------
1. Request: Set default WoL state according to nvram settings

Change: As Requested

Impact: None

2. Request: WRR between different COS queues at TX side

Change: Added in driver and in FW 4.8.53

Impact: None

3. Request: Add ability to change BCM8726 TX PreEmphasis using nvram
configuration

Change: When nvram config "Override pre-emphasis configuration" (75)
is set, use Tx pre-emphasis nvram configuration (47), lane0
value to set the Main Tap and lane1 to enable TX-PreEmphasis
in BCM8726

Impact: None

4. Request: Add basic support for BCM8481

Change: As Requested

Impact: None

5. Request: Limit Tx queue number to one for kernels 2.6.24 - 2.6.26
(non-TSS kernels with new NAPI)

Change: As Requested

Impact: None

6. Request: Add RSS support for old NAPI kernels (up to 2.6.24) that
support MSI-X

Change: As Requested

Impact: multi_mode = 1 is now the default for all kernels

Version 1.48.51 (Jan 26, 2009)
==============================

Fixes
-----
1. Problem: Load balancing didn't work

Cause: Driver assumed that there was Tx work as long as
driver packets producer and consumer were not equal

Fix: Changed driver's Tx work amount evaluation logic

Impact: None

Version 1.48.50 (Jan 22, 2009)
==============================

Fixes
-----
1. Problem: (CQ38862) modprobe fails to load driver on SuSE 11

Cause: SuSE 11 does not allow 3rd party modules to be loaded without
toggling a flag in /etc/modprobe.d/unsupported-modules

Fix: Toggle the bit during make install

Impact: None

2. Problem: Accessing nvram while the driver is down caused PCI error

Cause: The driver attempted to access the nvram while the device was
in D3 since it was disabled

Fix: Prevent nvram access when the device is down

Impact: None

3. Problem: FW assert while running multi_mode=2 with tx MULTI_QUEUE
enabled

Cause: start_xmit() selected different tx queue than the tx_lock was
taken

Fix: Implement dev->select_queue() callback so start_xmit() selects
the correct tx queue

Impact: None

4. Problem: Compilation problem with kernel 2.6.29

Cause: netif_rx_schedule and netif_rx_complete do not require the
device parameter anymore

Fix: Do not pass the device paramter for those functions for kernels
above 2.6.29

Impact: None

5. Problem: Invalid presentation of BCM8726 fw version

Cause: The register that holds the fw version is used for other
functionality as well, and it is run over after firmware is
loaded

Fix: Save the firmware version of all external phys in shared
memory, after firmware is loaded

Impact: None

6. Problem: BCM8726 may start tx laser before module detection occurs

Cause: Module detection used to be done during link update, which
probably would be after tx was enabled

Fix: From now on use interrupt driven event using GPIO3, to detect
module plugged in/out, and execute module detection then

Impact: None

7. Problem: 1G switch configuration (using the 5th lane) doesn't work

Cause: Support for Serdes (5th lane) was not maintained since no
production design used it and when switching to CL45 it stopped
working

Fix: In order for control the Serdes over Clause45, (and not
Clause22), it requires first one time register setting in
Clause22

Impact: None

8. Problem: Softlock during remove_one()

Cause: NAPI context was not released before unloading

Fix: Release NAPI context before unloading

Impact: None

9. Problem: False self-test failures due to MC_ASSERT

Cause: iSCSI FW sometimes report run-time warnings which are
acceptable and do not cause any harm

Fix: Do not check for MC_ASSERT. A real FW error will cause the
interrupt test to fail

Impact: None

10. Problem: Possible miss of FW response on unload

Cause: Missing memory barrier while waiting for FW response

Fix: Add read memory barrier

Impact: None

11. Problem: (CQ37809) loopback test failure

Cause: A link change interrupt might be queued and activated after
the loopback was set

Fix: Lock all PHY activities while running loopback test

Impact: None

12. Problem: (CQ39057) Everest, 57710 Error message:
bnx2x_start_xmit: BUG Tx ring full when queue awake

Cause: In kernels 2.6.24 - 2.6.26 (non-TSS kernels with new NAPI)
there can be a possibility that NAPI instance (fp instance)
other than the one moved Tx to XOFF state will wake the Tx
So, this is highly possible that start_xmit is called while
the ring is still full
In any other kernel this state is an obvious bug

Fix: Remove an error message in the code for the mentioned
kernels

Impact: None

Enhancements
------------
1. Request: Use FW 4.8.50

Change: As Requested

Impact: None

2. Request: BCM8726 should be able to link up at 1G

Change: Add support for 1G for BCM8726

Impact: When requested speed is 1G force, it will try to link in 1G
force. When the speed requested is autoneg, and the speed mask
capabilities contain 1G, it will try to autoneg in 1G as
well as in 10G

3. Request: (CQ39048) Add ability to change 8706 XAUI RX Equalizer
using nvram configuration

Change: When nvram config "Override pre-emphasis configuration" (75)
is set, use the 3LSB bits of RX_equalizer nvram configuration
(48) to set the BCM8706 XAUI RX Equalizer registers for each
lane

Impact: None

4. Request: Verify external phy image before ROM upgrade

Change: New headers will be added to the images of external phys to
be upgraded. Currently this list includes BCM8073, BCM8726
and SFX7101. The headers will be checked against fixed magic
number and specific phy type

Impact: From now on, external phy images MUST include image header

Version 1.48.11 (Jan 13, 2009)
==============================

Fixes
-----
1. Problem: Possible memory overrun on platforms with page size more
than 8K

Cause: "linearization" should take into an account system page
size and run or not run accordingly

Fix: Fixed the compilation condition

Impact: None

2. Problem: Compilation problem with kernel 2.6.28

Cause: struct net_device_ops was postponed to next release

Fix: Remove struct net_device_ops from compilation

Impact: None

Enhancements
------------
1. Request: Limit multi_mode to support only regular mode

Change: As requested

Impact: None

Version 1.48.10 (Jan 07, 2009)
==============================

Fixes
-----
1. Problem: (CQ39129) driver assert while logging out during iSCSI
max sessions test

Cause: QM initialization was wrong

Fix: Fix QM initialization

Impact: None

Version 1.48.9 (Jan 05, 2009)
=============================

Fixes
-----

1. Problem: (CQ38909) on IA-64 with TPA enabled, kernel memory was
sometimes smeared (depending on the MTU size)

Cause: The max TPA fragments assumed 4KB pages and that system had
16KB pages

Fix: Fix the SGE (TPA fragment) size to be system page size

Impact: Improved performance on systems with page size > 4KB like PPC
and IA-64

Version 1.48.8 (Dec 31, 2008)
=============================

Fixes
-----

1. Problem: (CQ38992) on IA-64 Driver crash when transmitting on all 8
functions in chariot IPv6 with tx checksum disabled scenario

Cause: FW read the buffer descriptor (BD) producer and after that the
BD itself before the BD content was updated. This is possible
on IA-64 due to weak ordered memory module

Fix: Add write barrier after updating the BD data and before
updating the BD producer

Impact: None

Version 1.48.7 (Dec 30, 2008)
=============================

Fixes
-----

1. Problem: (CQ38985) Port swap is not working for BCM8726

Cause: BCM8726 is driven by MDC/MDIO through single EMAC.
In case of port swap, the EMAC access was left with EMAC0

Fix: In case port-swap is enabled in the NIG, access MDC/MDIO via
EMAC1

Impact: None

2. Problem: BCM8726 was not reset when driver was unloaded

Cause: This phy hardware reset affects both ports and thus wasn't
used

Fix: When link needs to be reset, reboot the micro-controller of the
BCM8726

Impact: None

3. Problem: BCM8726 was not reset during init

Cause: This phy is connected using static port-swap, hence the reset
should have been triggered through the opposite port from the
spec

Fix: Set gpio1 during common init from port1 instead of port0

Impact: None

4. Problem: (CQ38991) In E1HMF mode some interfaces occasionally
misreport link speed

Cause: Races between interfaces during init cause an interrupt
event to be ignored

Fix: Flag the device as "ready for interrupts" prior to enabling
the interrupts

Impact: None

5. Problem: (CQ39057) Everest, 57710 Error message :
bnx2x_start_xmit: BUG Tx ring full when queue awake.

Cause: Tx BD producer update may not be "seen" by bnx2x_tx_int
function running on different CPU, thereby bnx2x_tx_int
may erroneously conclude that it may wake Tx.

Fix: Add smp_mb() after update of Tx producer before putting Tx
to XOFF state.

Impact: None

6. Problem: In E1HMF mode with multi queue, functions 2..7 cannot receive
data

Cause: Incorrect initialization of indirection table

Fix: Initialize correctly the indirection table

Impact: None

7. Problem: The driver debug crash dump does not handle cyclic rings
correctly

Cause: The debug prints were simply from start to end and did not
print anything in case start < end (cyclic rings)

Fix: Enhance the debug prints with cyclic logic

Impact: None

8. Problem: Packets dropped due to lack of host buffers were counted twice
- in good and bad statistics

Cause: Firmware does not maintain separate counters for
unicast/broadcast/multicast drops, therefore driver cannot
subtract these values from the good packet/byte counters

Fix: Fixed in FW 4.8.9

Impact: None

9. Problem: iSCSI FW: High non-paged host memory consumption

Cause: Unnecessary optimization of chipset<->memory bandwidth in
expense of memory consumption

Fix: Fixed in FW 4.8.9

Impact: None

Version 1.48.6 (Dec 18, 2008)
=============================

Fixes
-----
1. Problem: System hangs when running ifconfig on an 8 CPUs system

Cause: A loop variable was used again in an inner loop. That caused
an endless loop

Fix: Use another variable for the inner loop

Impact: None

2. Problem: Some stats names are not displayed but their values were
displayed in other stats

Cause: Incorrect condition caused to skip stats names but not their
values

Fix: Correct the condition

Impact: None

3. Problem: iSCSI FW: During connection establishment on-chip (option2),
in case we receive SYN/ACK with incorrect dst_mac the chip
gets stuck

Cause: This scenario led to accessing invalid PRAM address which
made the chip halt

Fix: Fixed in FW 4.8.8

Impact: None

4. Problem: NAPI poll mode was stopped (netif_rx_complete called) and HW
interrupts reenabled even if the whole device quota had been
consumed.

Cause: There was a bug in NAPI poll-mode canceling logic.

Fix: Fix the logic in NAPI poll method.

Impact: None

Version 1.48.5 (Dec 11, 2008)
=============================

Fixes
-----
1. Problem: TCP packets with VLAN weren't handled properly, when received
in non-accelerated VLAN traffic mode (when VLAN tag is not
stripped by the FW)

Cause: Driver didn't support receiving VLAN packets in
non-accelerated mode. for TPA packets, there was a wrong
IP header offset calculation and, as a result, writing IP
checksum to the wrong offset. Non-TPA packets weren't handled
right as well: driver always used vlan_hwaccel_receive_skb to
pass an skb with VLAN to the stack, while it should use
netif_receive_skb in non-accelerated case

Fix: Fixed IP header offset calculation for TPA packets. Fixed VLAN
skb handling
logic.

Impact: None

2. Problem: (CQ38698, CQ37931) No link when using direct attached copper
cable with BRCM8726 PHY

Cause: Passive copper cables should always operate in LRM mode rather
than in Limiting mode

Fix: In case of passive copper cables, link up in LRM mode

Impact: None

3. Problem: (CQ38815) iSCSI failure during hotplug

Cause: Not everything is setup before calling register_netdev().
pci_set_drvdata() and bnx2x_init_bp() were called after
register_netdev(). This potentially can also affect L2
because bnx2x_open() can potentially be called before
those 2 calls have successfully completed

Fix: Call register_netdev only at the end of successful setup

Impact: None

4. Problem: (CQ38862) modprobe fails to load driver on SUSE11

Cause: SuSE does not allow 3rd party modules to be loaded without
toggling a flag in /etc/modprobe.d/unsupported-modules

Fix: Toggle the bit through the packaging script

Impact: None

5. Problem: iSCSI FW: In non-aligned PDUs with data-digest enabled, the
data-digest is calculated to a wrong value

Cause: The CRC machine was not reset correctly in non-aligned PDUs

Fix: Fixed in FW 4.8.6

Impact: None

6. Problem: iSCSI FW: Connection wasn't initialized with the right
parameters for the TX in E1HMF mode

Cause: Initialization was done using SF mode

Fix: Fixed in FW 4.8.6

Impact: None

7. Problem: (CQ38886, CQ38888) iSCSI FW: Double-vlan was not supported
for iSCSI. The packet was transmitted with bogus IP length
and no inner-vlan

Cause: The vlan flag and the header builder command size weren't
set correctly

Fix: Fixed in FW 4.8.6

Impact: None

8. Problem: Byte counters statistics did not count the 4 FCS bytes

Cause: The FCS bytes were not counted

Fix: Fixed in FW 4.8.7

Impact: None

Enhancements
------------
1. Request: SFP+ optical module (MSA) vendor verification should
be optional when using BCM8726 PHY

Change: Verify the optical module vendor according to nvram
configuration option #81: "Optic Module Vendor
Enforcement"

Impact: The new nvram bit is visible using ediag version 4.8.3
or later

2. Request: In multi queue mode, separate FW stats per queue

Change: As requested

Impact: None

3. Request: Change some stats names:
pause_frames_received is now rx_pause_frames
pause_frames_sent is now tx_pause_frames
timer_max_events is now rx_constant_pause_events

Change: As requested

Impact: None

4. Request: Align with RMON MIB (rfc 1757):
net_device_stats.rx_bytes is total_bytes_received
net_device_stats.multicast is total_multicast_packets_received

Change: As requested

Impact: None

5. Request: Use static singlethread_workqueue shared for all bnx2x
interfaces

Change: As requested

Impact: None

Version 1.48.4 (Nov 26, 2008)
=============================

Fixes
-----
1. Problem: CNIC driver is failing on higher functions of 57711E

Cause: The status block ID for the CNIC was not assigned correctly
for higher functions

Fix: Assign the status block ID according to the function ID

Impact: None

Version 1.48.3 (Nov 20, 2008)
=============================

Fixes
-----
1. Problem: Intermittent MDC/MDIO failures on 8726 PHY

Cause: MDIO register access is sometimes broken since PHY is not hard
reset

Fix: Pull GPIO1 low for 1 ms after power-on. Note that the hard
reset is a shared resource on the PHY

Impact: None

2. Problem: gso_type indication was not set for TPA packets

Cause: gso_type wasn not set

Fix: Set gso_type accordingly

Impact: None

3. Problem: Possible false parity indication

Cause: When using 5 tuple hash (not used today) the searcher might
falsely indicate parity error

Fix: Mask bit 6 of the searcher parity errors

Impact: None

4. Problem: (CQ37809) Intermittent failures in ethtool diagnostic
(CQ36771) Calltrace and interface locks up when up/down
interface

Cause: If sp_task() is queued in the shared work queue after the
linkwatch, it will be starved and will not update the link
status until ethtool diagnostic ends and frees rtnl that
linkwatch is waiting for

Fix: Create private workqueue

Impact: None

5. Problem: (CQ38139) iSCSI FW: Performance < 40% of Peak Advertised

Cause: Inefficient implementation of ring management in firmware

Fix: Fixed in FW 4.8.4

Impact: None

6. Problem: (CQ38424) SAFC iperf drop result is 5 times higher than
previous build

Cause: Mis-configuration of the SAFC timeout

Fix: The new SAFC timeout will be 200usec

Impact: None

Version 1.48.2 (Nov 10, 2008)
=============================

Fixes
-----
1. Problem: SAFC packets were not generated periodically by NIG

Cause: A HW architecture bug

Fix: Fixed in FW 4.8.3

Impact: None

Enhancements
------------
1. Request: Support iSCSI MAC and VLAN per function in 57711E

Change: Added in FW 4.8.3

Impact: None

Version 1.48.1 (Nov 06, 2008)
=============================

Fixes
-----
1. Problem: Possible race between init_one() and open() with calling to
netif_carrier_off()

Cause: After register_netdev(), open() can be called at any time and
the interrupt handler can be called after that. If you get a
link change interrupt, the netif_carrier_* call from IRQ or
NAPI poll can race with netif_carrier_off() call in probe.

Fix: Move netif_carrier_off() to open()

Impact: None

2. Problem: Possible access to illegal addresses inside the chip during
self test

Cause: Loop size was given in bytes and not in number of entries

Fix: Fix the loop size

Impact: None

Enhancements
------------
1. Request: Fewer dropped packets when flow control is enabled on
57711/57711E

Change: As requested

Impact: None

Version 1.48.0 (Nov 03, 2008)
=============================

Fixes
-----
1. Problem: Failures on RH5 when using enabling and disabling the
functions one by one on 57711E

Cause: Unloaded driver tries to access the PHY to get its FW
version since RH calls "ethtool -i" periodically

Fix: Clear the PMF indication when the driver is unloaded

Impact: The PHY FW is inaccessible when the driver is unloaded

2. Problem: Searcher block initialization for 57711E is wrong

Cause: The searcher registers are split (same address for all
functions)

Fix: Use the port offset and not the function offset

Impact: None

3. Problem: Kernel panic when failing to load the driver

Cause: netif_carrier_off was called before making sure that
the driver can be loaded

Fix: Call netif_carrier_off as last action in the probe

Impact: None

Enhancements
------------
1. Request: Add iSCSI for 57711E

Change: FW 4.8.2 supports iSCSI for 57711E

Impact: None

2. Request: Add transmit multi queue support

Change: As requested

Impact: This fetaure is available on 2.6.27 kernel when using MSI-X

Version 1.46.12 (Oct 29, 2008)
==============================

Fixes
-----
1. Problem: (CQ37832) System crash when running TCP connections on
57711

Cause: Access to unsupported address in FW PRAM due to
increased FW size

Fix: Fixed in FW 4.6.21: Moved all operational FW code to
legal PRAM addresses

Impact: None

2. Problem: After some cases of driver failure, driver cannot be
re-loaded

Cause: The driver took the HW out of reset without making sure
that it was indeed in reset state

Fix: Reset the HW before taking it out of reset

Impact: None

3. Problem: (CQ37893) Driver failure when installed on RHEL4.5 from PXE
Server

Cause: MSI-X fails due to memory allocation failure and though MSI
registration succeeded interrupts are not received in MSI mode

Fix: Use INTx mode when MSI-X fails due to memory allocation
failure

Impact: None

Enhancements
------------
1. Request: Add debug module parameter to force MRRS value

Change: As requested

Impact: None

Version 1.46.11 (Oct 23, 2008)
==============================

Fixes
-----
1. Problem: (CQ37915) On 57710, if self-test is run on port 1, port 0 stops
transmitting/receiving traffic unless in promiscuous mode

Cause: Primary MAC address of port 0 is lost after the self-test on
port 1

Fix: Changed self-test to fix the problem

Impact: None

2. Problem: (CQ37087) iSCSI FW: Data digest error event found in event viewer

Cause: Wrong UPB command in non-aligned data that is adjacent to
iSCSI header in the TCP segment from the target

Fix: Fixed in FW 4.6.17

Impact: None

3. Problem: (CQ38061) iSCSI FW: Invalid iSCSI PDU seen while running
OEM diagnostic to Equallogic target

Cause: Misinterpretation of the 3720 RFC regarding data-in sequences
definition

Fix: Fixed in FW 4.6.17

Impact: None

4. Problem: (CQ37861) iSCSI FW: BSOD occurred while running iLab's TOE
automated tests and iSCSI traffic

Cause: Failed to identify task cleanup during processing of a
data-in PDU that belong to the same task

Fix: Fixed in FW 4.6.17

Impact: None

5. Problem: (CQ38088) iSCSI FW: FW assert occurred while passing CNIC
traffic

Cause: Race in iSCSI FW between writing task context entry using
the data path and writing R2TQE using the control path

Fix: Fixed in FW 4.6.18: Eliminate race, by using R2TQE write
through the data path

Impact: None

6. Problem: When enabling a lot of debug prints on a system with
many (more than 6) interfaces, timeout can occur on
driver load

Cause: Since printk is busy, it can take longer for operations
to complete

Fix: Increase the timeout value

Impact: None

7. Problem: After load failure, the driver cannot be re-loaded

Cause: The FW was not informed that the driver was unloaded

Fix: On load failure, send "unload" notification to the FW

Impact: None

Enhancements
------------
1. Request: (CQ38040) Do not use crc32c_le symbol

Change: Copied the function into the driver

Impact: None

Version 1.46.10 (Oct 20, 2008)
==============================

Fixes
-----
1. Problem: System panic under stress traffic

Cause: The alignment to the machine cache size was not calculated
correctly for the Rx buffer and so a buffer overrun occurred

Fix: Allocate the right amount of memory considering the cache
alignment

Impact: None

Version 1.46.9 (Oct 16, 2008)
=============================

Fixes
-----
1. Problem: (CQ37772) iSCSI FW: Bad data digest is transmitted

Cause: Missing initialization in FW when going out of slow start

Fix: Fixed in FW 4.6.16: Add rxmit parameters init to normal TX
flow

Impact: None

2. Problem: (CQ37809) Intermittent Failures in Ethtool Diagnostic

Cause: When setting PHY loopback, it required some time before
configuration is actually take place.

Fix: Add 200ms after setting the PHY loopback

Impact: None

3. Problem: Unable to receive packets on the iSCSI MAC address

Cause: Promiscuous in rx mode was ran over by resetting the
rx mode

Fix: Reset the rx mode before setting promiscuous mode

Impact: None

Enhancements
------------
1. Request: Add the licensing structure to the bnx2x_hsi.h

Change: As requested

Impact: None

2. Request: Set FW to machine cache alignment (up to 256B) for Rx
packets L2 data

Change: As requested

Impact: None

Version 1.46.8 (Oct 07, 2008)
=============================

Fixes
-----
1. Problem: A potential firmware bug when L2 packet is duplicated to more
than one L2 client when TPA is enabled

Cause: Buffer could have been released before it was read by all L2
clients

Fix: Fixed in FW 4.6.15

Impact: None

2. Problem: (CQ37471) iSCSI FW: (iLab test 5.12) TCP CLOSE timeout issue

Cause: Chip halted since handler apparently stuck in the queue

Fix: Fixed in FW 4.6.15

Impact: None

3. Problem: (CQ37244) iSCSI FW: (iLab test 5.10) Chip hangs when receiving
SYN+RST+ACK after SYN sent

Cause: SYN retransmission with invalid sequence number caused by not
rewinding the sequence number after retransmission

Fix: Fixed in FW 4.6.15

Impact: None

4. Problem: iSCSI FW: Chip halts after few unanswered connections attempts

Cause: After retransmits were done, the chip didn't return the
credits it should have

Fix: Fixed in FW 4.6.15

Impact: None

5. Problem: (CQ37668) iSCSI FW: Chip hangs when trying to connect to
iSCSI target with no licenses present

Cause: When licensing of new connection fails, there's a credit leak
which caused an invalid handler to wake up

Fix: Fixed in FW 4.6.15

Impact: None

6. Problem: (CQ37610) A potential problem if call to register_cnic during
MTU change

Cause: CNIC and the bnx2x drivers can be trying to setup the chip
at the same time

Fix: Check for intr_sem in register_cnic to prevent this problem

Impact: None

Enhancements
------------
1. Request: Allow better response time to SAFC packets

Change: Configure max-byte-credit as required for SAFC mode

Impact: None

2. Request: Add priority mapping table to map SAFC priority to HW queue

Change: As Requested

Impact: None

Version 1.46.7 (Sep 28, 2008)
=============================

Fixes
-----
1. Problem: (CQ37161) Running ifconfig down up on one interface can cause
other interface to fail

Cause: Overriding internal memory that belongs to the other interface

Fix: Writing only memory of the correct interface

Impact: None

2. Problem: (CQ37288) iSCSI FW: iSCSI offload with Everest is extremely
slow

Cause: PSH flag was not set in last PDU TCP packet

Fix: Fixed in FW 4.6.13

Impact: None

3. Problem: Possible overriding the internal memory and possible failure
to work with MSI-X when RSS and CNIC enabled

Cause: Allocate 16 queues for RSS + 1 queue for CNIC

Fix: Allocate only 15 queues for RSS

Impact: None

4. Problem: Lower performance on Big-Endian machines

Cause: Failure to read correctly the PCI_EXP_DEVCTL on Big-Endian
systems. Read PCI_EXP_DEVCTL to u32 variable instaed of u16
variable

Fix: Read PCI_EXP_DEVCTL to u16 variable

Impact: None

Version 1.46.6 (Sep 25, 2008)
=============================

Fixes
-----
1. Problem: (CQ37398) Issuing ifdown command on one port causes the
other port not to respond either

Cause: Clearing all entries in the CAM

Fix: Clear only the appropriate entries in the CAM

Impact: None

2. Problem: (CQ37407, CQ37508, CQ37509) Compilation fails on
RH 4.5, 4.6, 4.7

Cause: A compiler bug

Fix: Workaround in the code

Impact: None

3. Problem: (CQ36673) iSCSI FW: Hardware attention on MaxLuns

Cause: Activity count leak in Ustorm microprocessor

Fix: Fixed in FW 4.6.12

Impact: None

4. Problem: (CQ37224) iSCSI FW: (iLab test 5.10) Hardware attention
(Microcode assert)

Cause: iSCSI FW: SYN+RST drop after SYN sent caused AC leak
in TStorm microprocessor in option2

Fix: Fixed in FW 4.6.12

Impact: None

5. Problem: iSCSI FW: (iLab test 6.1) Hardware attention
(Microcode assert)

Cause: Missing update of R2T buffer offset

Fix: Fixed in FW 4.6.12

Impact: None

6. Problem: Possible false warning (not a failure) in the idle
check section of the self test regarding the
BRB1_PRTY_STS register

Cause: The condition was not masked properly

Fix: Fixed the condition check for that register

Impact: None

Enhancements
------------
1. Request: Add support for BCM8726 (Dual port phy SFP+ ) including
MSA module recognition and verification

Change: As Requested

Impact: None

Version 1.46.5 (Sep 17, 2008)
=============================

Fixes
-----
1. Problem: (CQ36478) MSI fails on Big-Endian systems

Cause: The IGU was configured to swap the data over the PCI

Fix: Config IGU not to swap the data and add swap in the driver
where it is necessary

Impact: None

2. Problem: (CQ37309) Can not compile on some old kernels

Cause: Call to pci_disable_msi() was not under appropriate #ifdef

Fix: Add the appropriate #ifdef

Impact: None

3. Problem: Self test sometimes indicates on a failure

Cause: A test result was declared as an error instead of a warning

Fix: Declare the test result as a warning

Impact: None

Version 1.46.4 (Sep 16, 2008)
=============================

Enhancements
------------
1. Request: CNIC enabled in default compilation

Change: As Requested

Impact: None

Version 1.46.3 (Sep 11, 2008)
=============================

Fixes
-----
1. Problem: (CQ34165) High number of pause frames

Cause: The thresholds in the receive buffer needed some
tuning

Fix: Tuned the thresholds in the receive buffer

Impact: None

2. Problem: (CQ36559, CQ36989) System crash when working on PPC
with 64KB page

Cause: The allocated buffer was bigger than the PCI mapped
buffer, and in the 64KB configuration the buffer is
aligned only to 128 bytes and so the packet can
overstep the PCI mapped area and cause a fatal error

Fix: Map the same size as the allocated buffer size

Impact: None

3. Problem: (CQ36479) EEH recovery causes system crash

Cause: When EEH detects an i/o error it resets the device thus
it cannot be accessed. In this case the driver needs to
unload its interface only with OS, kernel and network
stack but not with the device.

Fix: Add a special unload function for EEH recovery that
does not access the device

Impact: None

4. Problem: Option2 RST did not complete

Cause: Missing context initialization in FW

Fix: Fixed in FW 4.6.10

Impact: None

5. Problem: (CQ37090) Placement of RQ data to wrong address

Cause: ASM problem

Fix: Fixed in FW 4.6.10

Impact: None

6. Problem: (CQ36912) BSOD when destroying erroneous connections

Cause: Activity count leak

Fix: Fixed in FW 4.6.10

Impact: None

7. Problem: (CQ 36987) Unable to perform media changer/tape functions

Cause: Bad padding calculation in long PDUs

Fix: Fixed in FW 4.6.10

Impact: None

Enhancements
------------
1. Request: Incorporate latest firmware 4.6.10

Change: As Requested

Impact: None

2. Request: Add stats counter for NIG timer max events

Change: As Requested

Impact: None

3. Request: Enable timer scan for CNIC

Change: As Requested

Impact: None

4. Request: Add support for using MSI interrupt mode

Change: As Requested

Impact: None

5. Request: (CQ36758) Firmware now enforces iSCSI licensing and fails
the offload if no iSCSI initiator license exists

Change: Added in FW 4.6.10

Impact: None

Version 1.46.2 (Aug 25, 2008)
=============================

Fixes
-----
1. Problem: (CQ36510, CQ36583) Link LED does not turn off when 1G
link is lost when external PHY is present

Cause: The current code manually turned off the 10G LED but
did not handle other speeds which are controlled by HW.
Since the HW detect link with the external PHY, the
link LED stayed on

Fix: Turn off the LED for all speeds manually when link goes
down

Impact: None

2. Problem: Packets with bad TCP/UDP checksum error are dropped

Cause: Actively dropping packets with bad TCP/UDP checksum in
the driver

Fix: Do not drop packets with bad TCP/UDP checksum - let the
stack decide what to do with them

Impact: None

3. Problem: Some packets are dropped without showing on any
statistics counter

Cause: The driver assumed that packets which were identified
as bad are counted by the FW, but the FW does not count
those when configured to pass them

Fix: Add counters in the driver

Impact: None

4. Problem: (CQ36153) Flow control doesn't work against non KR switches

Cause: Missing support for clause-37 auto negotiation

Fix: Add support for clause-37 auto negotiation

Impact: 0.5 seconds delay during autoneg

5. Problem: Link dangling during init

Cause: no delay after initial link change interrupt

Fix: Add 30ms before allowing link update indications

Impact: Additional 30ms during init phase

6. Problem: Unable to load driver after iSCSI boot under incoming
traffic

Causes: The reset function after iSCSI boot did not handle
closing incoming traffic

Fix: Close the port to prevent Rx traffic and clear all
buffers

Impact: None

7. Problem: (CQ36408) Failed driver disk installation with SuSE10
and RH4

Cause: The CRC module is not part of the Kernel in those
distributions

Fix: Special driver disk compilation mode to include the CRC
routine in the driver though it is an external module
in normal installation with those distributions

Impact: The driver in the driver disk is less efficient due to
the CRC algorithmic implementation and not static tables
as in the CRC module which is used when loading the driver
normally under SuSE10 and RH4

8. Problem: (CQ34921) Possible memory leak

Cause: rx_page_ring was not freed

Change: free rx_page_ring

Impact: None

9. Problem: (CQ36242) brb_truncate statistics increments to very
high numbers

Cause: brb_truncate_discard is a 4 bytes variable but 8 bytes were
copied to ethtool

Change: use brb_truncate from NIG and extend it to 8 bytes

Impact: None

10. Problem: Tx Pause were not send on 1G link

Cause: Missing initialization to the EMAC TX_MODE

Change: Set FLOW_EN bit in the TX_MODE in addition to the
EXT_PAUSE_EN

Impact: None

11. Problem: (CQ36361) Changing speed to 1G on KR switch side
results in no link in OS

Cause: When Serdes is configured to 1G, it should remove
setting MDIO_SERDES_DIGITAL_MISC1_FORCE_SPEED_SEL bit in
MDIO_REG_BANK_SERDES_DIGITAL

Change: Unset MDIO_SERDES_DIGITAL_MISC1_FORCE_SPEED_SEL bit for
every link change

Impact: None

12. Problem: Possible loss of attentions

Cause: Attention mask register was manipulated without a proper lock

Change: Protect attention mask register using hw lock, use read
modify write on this register

Impact: None

13. Problem: HW lock was sometimes not taken

Cause: HW lock was not taken per function

Change: use lock control per function

Impact: None

14. Problem: (CQ36089) RX counter on all functions are incorrect

Cause: tstorm_client.statistics_counter_id was 0 for all functions

Change: set tstorm_client.statistics_counter_id to the cl_id of the
function

Impact: None

15. Problem: (CQ36090) down/up of the interface during traffic on
the other interface caused traffic to stop

Cause: Aggregation context must be initialized only at COMMON init
block

Change: Change initialization code and init-tool output

Impact: None

16. Problem: (CQ35672) Doorbell was arriving after halt and before
start ramrod

Cause: XON/XOFF flow control should be disabled in NIC close flow

Change: Fixed XON/XOFF code

Impact: None

17. Problem: (CQ34555) MSI-x PCI spec aberration

Cause: PBA table starts from the middle of a page

Change: Use GRC access instead of BAR access

Impact: None

18. Problem: Lost link indication in BCM8073.

Cause: During link establishment LASI latched signal
wasn't reset and stopped link change indication

Change: Fixed flow to clean latched LASI signal

Impact: None

19. Problem: Declaring bootcode timeout too soon

Cause: The bootcode can take a while to set a link
when a link is needed (for example, WoL is
enabled). The driver should allow adaptive
scheme to wait for the bootcode

Change: Waiting up to 2 seconds in 10ms intervals

Impact: In some cases, the driver unload process
will take up to 2 seconds

20. Problem: Wrong WoL capability report

Cause: The WoL capability was read from the nvram
which was not always updated

Change: Determine the WoL capability from the PCI
configuration space

Impact: None

21. Problem: (CQ36644, CQ366697, CQ36928, CQ36983) On some cases
with low traffic, the computer was irresponsive up to
the point of soft-lockup and even hard lockup.
Ping-pong latency tests always hit this problem and so
get very low result

Cause: If the FW was at the end of the Rx page, the driver
will already be at the beginning of the next page. In
this case the condition of having the driver and the FW
on the same pointer was never true and so the driver
kept polling until timeout or another packet came in.
On driver unload (including intermediate driver unload
like in MTU change or self-test) the lockup was fatal

Fix: Change the check for "now work" to handle end of page
as well

Impact: None

22. Problem: (CQ36697 CQ36771) Interface locks up when up/down interface

Cause: In nic_unload(), call to netif_poll_disable() cause to set
__LINK_STATE_RX_SCHED flag that is checked in dev_close() in
a loop forever. This flag is cleared by netif_rx_complete()
called by bnx2x_poll() which is not called if !netif_running()

Fix: Reorder nic_unload() - first close interrupts, then only if
netif_running() call netif_poll_disable()

Impact: None

23. Problem: (CQ36795) driver fails to load after iSCSI boot

Cause: Unloading UNDI by the driver is protected by a HW lock. With
a KR (8073) interface, unloading the UNDI takes more than
1 sec. Taking the lock by another driver times out after 1 sec
then the driver tries also to unload UNDI.

Fix: Clear UNDI signature and release the lock. Only the driver
who saw UNDI signature will continue to unload UNDI.

Impact: None

24. Problem: Allocate skbs for unused aggregation queues in 57710

Cause: Allocate skbs for 64 aggregation queues but 57710 has only 32

Fix: Allocate skbs for max_agg_queues according to chip id

Impact: None

25. Problem: Wrong cleanup on exit from nic_load() in case of a failure

Cause: Upon some failure nic_load() exits without disabling and
freeing the interrupts

Fix: Fix to disable and free the interrupts in that case

Impact: None

26. Problem: Potential link problem when loading two ports with 8073
PHY

Cause: Initializing the 8073 PHY takes more than 1 seconds and
the HW lock might expire since it is only trying for 1
second

Fix: Increase the HW lock timeout to 5 seconds

Impact: None

27. Problem: XAUI link on port0 goes down and then up, when the link
on port1 is changed

Cause: When master port (port1) is down, it will also cause
the blade side down. In turn, PLL will change speed
from 10G to 1G. It will cause XAUI clock to both ports
down and then up again

Fix: Set bit in the BCM8073 that enables the fix

Impact: None

28. Problem: (CQ36772) KR with 8073 PHY sometimes does not establish
link

Cause: A missing delay between initializing the PHY SPI ROM
and inserting the PHY back to low power mode

Fix: Add 15ms delay after loading the SPI PHY ROM which is
before entering low power mode

Impact: None

29. Problem: Sometimes when unloading the driver a message will
appear: "sp_running (j 1)"

Cause: Wrong condition, the message should appear only if the
counter (j) is greater than 1000. This is a false alarm

Fix: Fix the print condition

Impact: None

30. Problem: When upgrading 8073 SPI ROM PHY to version 0103 the
link will not come up

Cause: Register 0x8370 is no longer required in the new
version and writing to it cause the link not to come
up

Fix: Remove the write to address 0x8370

Impact: None

31. Problem: On some KR boards when loading driver on port0, and
port1 is not loaded, sometimes the XAUI link is not
coming up

Cause: The 8073 PHY has two ports that share a single clock.
This clock is routed to a port deemed to be the master
(port 1), and then a PLL at the master sets the clock
frequency and routes the buffered clock to both the
master XAUI interface as well as the slave (port 0)
XAUI interface. If port 0 is loaded while the 8073 PHY
SPI ROM is not loaded, the PLL for port 0 is not
guaranteed to lock

Fix: First driver to be loaded reset and download SPI ROM on
both ports of the 8073 PHY during one-time
initialization

Impact: The 8073 PHY is only reset when both ports are brought
down

32. Problem: On some KR boards when unloading driver on port1 port 0
might loose link

Cause: The 8073 PHY has two ports that share a single clock.
This clock is routed to a port deemed to be the master
(port 1), and then a PLL at the master sets the clock
frequency and routes the buffered clock to both the
master XAUI interface as well as the slave (port 0)
XAUI interface. If port 1 is unloaded while port 0
is in use, the port 0 PLL might loose lock

Fix: Do not reset the PHY if either driver is still up

Impact: The 8073 PHY is only reset when both ports are brought
down

33. Problem: When loading driver after it was loaded before, packets
are getting into the chip before the MAC addresses are
configured (but not into the host)

Cause: The HW filters are not cleared when the driver is
unloaded so previous driver configuration is still
present

Fix: Clear HW filters so no packet will come in when driver
is unloaded

Impact: None

34. Problem: Driver does not pass the last version of checkpatch.pl

Cause: Some updates to the script found some coding standard
violations in the code

Fix: Fixed all reported errors and spelling mistakes

Impact: None

35. Problem: (CQ36492) rx_csum_offload_errors increments for any
none TCP/UDP packet

Cause: Parsing CQE flags incorrectly

Fix: Parse CQE flags according to CQE status bits

Impact: None

36. Problem: Packets with IP checksum error are dropped

Cause: Dropping packets with IP checksum error

Fix: Pass packets with IP checksum error to the stack. Drop
only packets with L2 errors

Impact: None

37. Problem: (CQ46480) The nomcp module parameter is causing kernel
panic

Cause: This debug parameter was not needed and not maintained

Fix: Remove this debug parameter. The driver can detect if
the FW is missing and act accordingly

Impact: None

38. Problem: Per function statistics are not cleared on driver load
unload

Cause: The FW statistics area was not cleared on driver load

Fix: Clear FW statistics area when loading the driver

Impact: None

39. Problem: (CQ36204, CQ36423) Self-test memory failures reported
intermediately

Cause: Did not apply the right mask on the HW report caused
some false positives

Fix: Use mask to check only the memory errors report

Impact: None

40. Problem: (CQ36497) Self-test idle_check part is failing

Cause: Did not apply the right mask on the HW report caused
some false positives

Fix: Use mask to check only the memory errors report

Impact: None

41. Problem: (CQ36514) Failed to load the driver after iSCSI boot on
SuSE10 SP2

Cause: The built-in driver from the SuSE10 SP2 (1.42.3) was
loaded after the iSCSI-boot

Fix: Added update.post file to SuSE10 SP2 dd.iso

Impact: None

42. Problem: (CQ36382) Low 1G UDP performance with one connection
with flow control disabled

Cause: The credits in the transmitter HW caused too much gap
between UDP packets in case the flow control was
disabled

Fix: Use the same HW credit as if the flow-control is
enabled when the line speed is 2.5G or less

Impact: None

43. Problem: (CQ35662) NVRAM pre-emphasis support does not take
effect

Cause: Current nvm values didn't actually affect the phy

Fix: To keep backward compatibility, only in case the
"Override pre-emphasis configuration" nvm option is
enables, it sets the the tx preemphasis and rx
equalizer values for the 4 lanes according to the "XGXS
backplane Tx pre-emphasis matrix coef." and "XGXS
backplane Rx equalizer matrix coef." respectively

Impact: None

44. Problem: Prevent possible glitch due to speed change without
link down in the middle

Cause: Currently the NIG goes into drain mode only after link
down. If the only the speed was changed from 1G to
100Mb, for example, without link-down indication then
the FIFO isn't cleaned and glitch due to clk change may
occur

Fix: On speed change set the NIG into drain mode

Impact: Several packets may be dropped, but it's ok, since we
assume that anyhow several packets were dropped due to
the link down

45. Problem: Fix EMAC initialization setting

Fix: Currently it is configured inside the enable emac
before configuring the EMAC mode. Changed to be after
that and should be disabled (with the drain mode
setting) at the entrance of the link_update function.
In addition, in link down, after putting the nig into
drain mode this register should also be disabled.

After configuring the mode and before opening the
nig_emac#_en, reset the EMAC_REG_EMAC_RX_MODE and
EMAC_REG_EMAC_TX_MODE

Impact: None

Enhancements

2.6.26 except unloading and loading the driver

5. Request: Do not display internal FW version and enhance
readability of the bootcode version

Change: As requested

Impact: None

6. Request: Optimize link setup and support 2.5G

Change: Link will be configured on the external PHY before

SuSE9/10

Cause: Some changes for the upstream kernel were not
backwards compatible

Change: Added backwards compatibility code

Impact: None

6. Problem: (CQ35571) When running dozens of connections
on both ports, receiver freezes

Cause: A race between the aggregation timer and the swapping
of aggregated connections

Cause: Broken in last drops

Change: Fix the errors

Impact: None

6. Problem: (CQ35124) Kernel panic when unloading NIC with shared
INTA

Cause: The interrupts were masked when unloading, but the
handler was still present. In case of shared INTA
line, the handler was called after freeing the
resources due to other device interrupt

Change: Free the interrupt handler when masking all
interrupts on unload. Clear old interrupt before
registering the IRQ on load.

Impact: None

7. Problem: Failed to re-load the driver (after unload) on the
upstream kernel

Cause: The fast path structures which are used by NAPI where
released on unload and re-allocated on load

1. Problem: (CQ #33148) After "make install" command 'modprobe bnx2x'
displays "Module bnx2x not found".

Cause: Linux Makefile runs depmod automatically only if System.map
exists.

Change: Run depmod after modules_install.

Impact: None

2. Problem: (CQ #33054) Link is not detected after configuring BCM57710
port with Suse 10Sp1.

Cause: HW fails to use INTA after using MSI-X.

Change: Set MSI_MSIX_INT_EN bit in HC_CONFIG REG to use INTA after
MSI-X.

Impact: None

3. Problem: (CQ #33190) ifconfig command showed errors received. But
ethtool -S ethx did not show any errors.

Cause: Some error counters did not have a bin to be printed by
ethtool -S command.

Change: Add appropriate bins for the missed counters.

Impact: None

4. Problem: BSOD on T1002 boards.

Cause: A new code was added that manipulate GPIO 1 for external phy
reset. On T1002 board this GPIO control the PERST_L_BYPASS.

Change: Do not manipulate GPIO 1 on T1002 boards

Impact: None

Enhancements
------------
1. Feature: Add support for IPv6 checksum and IPv6 TSO.

Change: The support was added

Impact: None

2. Feature: Add fan failure detection and external PHY power down for the
A1022G

Change: When a fan failure is detected (indicated by SPIO5) on the
A1022G, the driver will shutdown the PHY (reset and low power
mode, using GPIO1+2) and issue a warning message

Impact: When fan failure occurs the link will go down until server
reset

Version 0.40.17 (December 17, 2007)
===================================

Fixes
-----
1. Problem: (CQ #33023) Pause RX is on when driver is loaded with
MTU > 4500.

Cause: Pause mode was computed from the requested flow control
parameter in NVRAM without considering the MTU size.

Change: Resolve the pause mode only before advertising the flow
control.

Impact: None

2. Problem: Pause autoneg can be set on for XFP cards.

Cause: Pause autoneg mode was always accepted from user.

Change: Pause autoneg is not supported if speed autoneg is not
supported (e.g. XFP cards).

Impact: None

3. Problem: (CQ #33044) make install fail.

Cause: No make install target in Makefile.

Change: Add make install target to Makefile.

Impact: None

4. Problem: (CQ #33057) No README.TXT in driver release folder.

Cause: No README.TXT in driver project.

Change: Add README.TXT in driver release folder.

Impact: None

5. Problem: (CQ #32541) No README.TXT in driver tarball.

Cause: No README.TXT in driver project.

Change: Add README.TXT to driver tarball and change the directory
name.

Impact: None

Enhancements
------------
1. Request: Add parity and assert regs for idle check.

Change: The check was added

Impact: None

2. Request: Add workaround for threshold mechanism for usdm-dp

Change: The workaround was added

Impact: None

3. Request: Add workaround for full Tetris buffer bug.

Change: The workaround was added

Impact: None

4. Request: Add support for the SFG10 PHY

Change: The support was added

Impact: None

5. Request: Add support for the BCM8072 PHY

Change: The support was added. The code is still not 100% functional

Impact: None

6. Request: Change the MDC/MDIO CL45 scheme

Change: The functions are more generic:
- Supports different MDC/MDIO controller
- Reduce the clock to 2.5MHz
- Less PIO writes (writing all the required information at
one attempt)

Impact: All external PHY access are using a slower (standard)
MDC/MDIO clock

7. Request: Hard reset external PHYs

Change: The external PHYs are now reset via GPIO. Before working with
an external PHY, a reset pulse of 1ms is generated, and when
the driver is down, the external PHY is kept in reset

Impact: Link partner should always see link down when the link is down

Version 0.40.16 (November 29, 2007)
==================================

Fixes
-----
1. Problem: (CQ #32296) VLAN broken on older Kernels.

Cause: vlan_kill_vid() removed in newer versions is needed by older
kernels to allow loading.

Change: Re added function.

Impact: None

2. Problem: (CQ #29543) System panicked if receiving UDP data while load
and unload

Cause: sp_task work was not synchronized with int_disable_sync()

Change: move sp_task to work_queue element

Impact: None

3. Problem: (CQ #32430) XFP port showed link lights on and link
detected = yes when configured port up with no cable
attached

Cause: Link_up was declared by local phy (XGXS) link up without
the external phy (8705) link status

Change: Link up is now the combination of local phy (XGXS) link up
and external phy (8705) link up

Impact: None

Enhancements
------------
1. Request: Print PCI link properties upon load.

Change: The print was added

Impact: None

Version 0.40.15 (November 15, 2007)
==================================

Fixes
-----
1. Problem: On heavy traffic scenarios, the machine halted due to
PCI problem

Cause: A HW change in A1 boards requires some registers that
controls the PCI credit to be changed as well

Change: Updating the PXP credit registers

Impact: None

2. Problem: (CQ #31120) The traffic LED was not active for lower
speeds

Cause: A new bootcode is required to set the traffic LED
when the speed is less then 10G (using the emac and
not the bmac)

Change: The set LED routine was updated and bootcode 4.0.10
or above is required to have the LED functional

Impact: None

3. Problem: Found a bug when doing ifconfig down/up during
traffic. In this case FW can assert

Cause: A packet that was received before unloading driver
stayed in Pbuff, and was processed after loading the
driver again

Fix: Added the reordering mechanism to slow path handlers

Impact: Implementation of all L2 slow-path commands was modified

4. Problem: (CQ #30160) Removed false positives from the self test
(ethtool -t)

Cause: Many tests in the self test were designed to check halted
system (after fatal error) and the test assumed that the
chip is idle

Fix: Any test that can happen while the chip is operational was
changed to "info" debug print and is not counted as warning
or error

Impact: The self test is more reliable

Enhancements
------------
1. Request: Forward preparation in the code for 57711

Change: Using only two DMAE clients per port. Using "port" instead of
"function".

Impact: Not visible to the user

2. Request: Block RX Pause if Auto-pause was selected and the MTU > 4500
to prevent performance retrogression when using PAUSE with big
packets

Change: The auto-pause resolution will be only TX pause if the MTU
is larger than 4500. Force pause mode will be obeyed as
requested

Impact: Jumbo frames with auto-pause will achieve higher throughput

3. Request: Report HW errors

Change: Parity and blocks errors attentions code was added to the
driver. Not all indications are enabled.

Impact: In case of an assert in the chip, the user will get an
error notification

4. Request: Added the ability to support multi interrupt queues from
kernel 2.6.24 and above

Change: Allow ISR and NAPI (the stack processing) to run on several
CPUs. The new feature is disabled by default

Impact: Can reduce latency in some cases

5. Request: Move slow-path to work-queue to allow sleeps

Change: The slow-path is now implemented as work queue

Impact: Better fairness to other host drivers

6. Request: Changes with statistics requirements due to
performance enhancement and preparation for next
features.

Change: a. Removed rcv_error_bytes
b. Replaced errors_discard stat by: mac_discard stat,
checksum_discard stat and packet_too_big_discard
stat
c. Removed statistics histogram

Impact: The displayed statistics format was changed

7. Request Remove FW interrupts that are not needed

Change: FW no longer interrupts the driver for reading a new slow-path
element (it updates driver only when completing processing it)

Impact: None

8. Request: Support easier SuSE compilation

Change: In previous version, a flag in bnx2x.c was required
in order to compile under SUSE. In the new implementation
the make file can be used in the following way:
SLES9 command: make EXTRA_CFLAGS+=-DBNX2X_SLES_9
SLES10 command: make EXTRA_CFLAGS+=-DBNX2X_SLES_10

Impact: SLES compilation procedure is different now

Version 0.40.14 (November 06, 2007)
==================================

Enhancements
------------
1. Naming the TCP performance improvement feature TPA (still for demos only)

Version 0.40.13 (November 05, 2007)
==================================

Enhancements
------------
1. Added support for L2 Rx TCP performance improvements in a special mode
(implementation for demos only). This support is disabled by default and
requires a change of compilation flag to enable.
2. Added support for vanilla kernel 2.6.18.5, SLES9, and RHES4

Version 0.40.12 (October 29, 2007)
==================================

Fixes
-----
1. Problem: A fragmented Tcp/Udp packet might have been wrongly dropped

Cause: parser doesn't checks tcp/udp checksum for fragmented
packets

Fix: FW will report to driver the tcp/udp checksum wasn't
Validated if the packet was fragmented

2. Problem: ethtool -S|r|t eth[x] on un-configured port causes
errors/panic

Cause: When port is un-configured memory is not allocated and
blocks in chip can be in reset

Fix: Check driver state in nway_reset() and self_test() and
check memory pointer in get_ethtool_stats()

Enhancements
------------
1. Supporting the upstream Kernel including new NAPI approach
2. Open source coding standard modifications throughout the code,
including new init code, new HSI header files, new registers
definitions, SPARSE fixes and checkpatch.pl fixes
3. Replaced patches mechanism with #ifdefs
4. Supporting big-endian machines
5. Supporting nVidia chipsets with MCP55
6. Support checksum offload for A1 boards (modification with some flag in
PBF command)

Cause:
In most cases, the indication of RX checksum was wrong
causing the Linux stack to recheck.

Fix:
Indication mistake was fixed.

2. Problem:
NFS UDP test failed writing to server.

Cause:
Incorrect HW init values.

Fix:
HW init values were corrected in the driver.

3. Problem:
MTU change cause system to assert.

Cause:
Memory leak in the ifconfig up/down sequence.

Fix:
Memory leak fixed in driver.

Fix:
Driver related code was fixed.

Version 0.27.1 (Apr 23, 2007)
============================

New features:
-------------

1. Added speed and activity support for LEDs.

Fixes:
------

1. Problem:
Low performance when running Netperf TCP_RR.

Cause:
Driver bug caused a the driver to enter a busy loop in
certain cases when there was no RX processing queued.

Fix:
The logic used to decide if there is pending RX work was
corrected.

2. Problem:
XFP link detection problem - intermittent issue.

Cause:
Driver would not get link change interrupt.

Fix:
Corrected the setting of the link change interrupt.

Broadcom NetXtreme II iSCSI Driver
For Linux

Copyright (c) 2006-2011 Broadcom Corporation
All rights reserved.

Version 2.6.2.4c (Feb 01, 2011)
===============================

Fixes
=====
1. Problem: Cont00052673 - iLab failed test6_14 - delayed iSCSI response
Cause: A bug was found in the ep_disconnect routine where the
session variable did not get initialized correctly. This
bug will cause TCP abortive disconnect to be requested
unconditionally.
Change: Fixed the initialization bug
Impact: All

Version 2.6.2.4b (Jan 14, 2011)
===============================

Fixes
=====
1. Problem: Cont00052132 - iSCSI has poor write IOPS at 1K block size
Cause: A soft lockup for 10s was observed with this and various
different I/O size test where as soon as the bh is released,
the scsi_next_command routine will trigger and the queue
lock will get stuck.
Change: - Restored all CQE processing back to the cnic tasklet bh
and modified the session lock granularity
- Modified the event coalesce algorithm to include the
cmd_cmpl_per_work module param
Impact: All

2. Problem: Cont00052131 - Cannot establish solid offload connection to
Dell MD3220i target from SLES11sp1 (RHELS is okay)
Cause: The problem was caused by the deferred CQE processing to
workqueue scheme which caused nop timeouts during logouts.
Change: The new CQE processing scheme no longer uses workqueue.
Impact: All

3. Problem: Cont00051479 - bnx2 unable to compile under RH5.6ss3
Cause: The bnx2i makefile did not accommodate for native RHELS5.6
installations either.
Change: Modified the bnx2i Makefile which will now examine the
...kernel.../linux/include/version.h file for the corresponding
RHEL version that it is compiling against.
Impact: All

Enhancements
============
1. Updated README for Cont00052157 to update the open-iscsi util

Version 2.6.2.3g (Jan 04, 2011)
===============================

Fixes
=====
1. Problem: Cont00051896 - iSCSI Read throughput underperforms at lower
request sizes with higher qdepths for 5771X
Cause: The new workqueue CQE processing mechanism was not tuned
for this scenario
Change: Various modification has been included for performance
optimization
Impact: All

Enhancements
============
1. Feature: Removed the scsi_flush_workqueue call and use a hba workqueue
array instead. This eliminates the potential libiscsi softlock
that one connection is performing scsi cleanup while the other
is undergoing scsi_flush_workqueue.
Impact: All

Version 2.6.2.3f (Dec 20, 2010)
===============================

Fixes
=====
1. Problem: Cont00051815 - kernel BUG - logging into EMC NX4
Cause: This target uncover a timing bug in the CQE processing call
in the mtask transmission. The nopin response got
processed before the nopout request was returned to the
stack. This causes the nopout request to timeout all the
time as the nopin responses would never get processed.
Change: Removed the CQE processing in mtask requests. This is not
necessary.
Impact: All

Version 2.6.2.3e (Dec 17, 2010)
===============================

Fixes
=====
1. Problem: Cont00051647 - Unable to logout of Dell MD3220i target for
RHELS6.0
Cause: Upon logout or shutdown, a scsi sync cache cmd will get
transmitted while the scsi worker is being blocked. Since
this is a fastpath cmd, the response was queued to the
scsi scsi workqueue which resulted in a lost response.
When this happens, the sync cache logic in the kernel will
block forever.
Change: Upon receiving a scsi sync cache cmd, the cqe processing will
switch to direct processing instead of deferring to the wq
Impact: All

Enhancements
============
1. Feature: No longer have to flush the entire shost workqueue for every
connection termination. In RHELS6.0, the cancel_work_sync function
will remove the connection's single entry to the shost's workqueue.
Impact: All

2. Feature: Added retry logic in the send nl mesg routine for robustness
Impact: All

Version 2.6.2.3d (Dec 15, 2010)
===============================

Fixes
=====
1. Problem: Cont00051625 - call trace while ifdown with traffic
bnx2i_conn_worker
Cause: Under certain ifdown cases, the bnx2i_ep and the bnx2i_conn are
not associated when going through chip_cleanup. The previous fix
did not take this into consideration
Change: Moved the disabling of the workqueue to hw_ep_disconnect under
bnx2i_conn validation check
Impact: All

Version 2.6.2.3c (Dec 14, 2010)
===============================

Fixes
=====
1. Problem: Cont00051625 - call trace while ifdown with traffic
bnx2i_conn_worker
Cause: During ifdown, the bnx2i_stop code will clean up all active
connections from the chip. However, because of the new workqueue
data processing architecture, the workqueues for the already
cleaned connections were still being called. This has created
a window of opportunity for the libiscsi2 layer to get into a
continuous locking/unlocking via the task_xmit path.
Change: Added the disabling of the workqueue for every active iSCSI conn
before chip cleanup.
Impact: All

2. Problem: Cont00051647 - Unable to logout of Dell MD3220i target
Cause: The scsi_flush_work call in the ep_disconnect was waiting
indefinitely for outstanding nopout cmd which was never sent during
the SCSI sync cache phase
Change: Removed the scsi_flush_work call until conn_destroy to align with
internal scsi state. Note that all outstanding scsi work must be
flushed before the bnx2i_conn gets destroyed.
Impact: All

Version 2.6.2.3b (Dec 07, 2010)
===============================

Fixes
=====
1. Problem: Cont00051499 - Call trace seen with bnx2i_process_new_cqes
Cause: For targets which employs ip redirect, a remote abort/close
event would occur. However, these were not being handled
correctly under the new cqe processing architecture
Change: Added session recovery workqueue to defer all remote abort/close
requests
Impact: All

Version 2.6.2.3a (Dec 06, 2010)
===============================

Fixes
=====
1. Problem: Cont00050655 - Low read/write IOPS on linux configuration
57711
Cause: The chip was being underutilized due to the mutual
starvation in the bottomhalf tasklet between the fastpath's
EQ->CQE handling and the SCSI ML's queue command requests
Change: Alleviate the processing time of the EQ->CQE by creating
a workqueue and also added processing of such in the
queuecommand's bh.
Impact: All

2. Problem: Cont00051427 - Session recovery seen after stopping I/O
traffic on Lefthand P4300 target
Cause: The nopout's reserved field was not being initialized to zero
before being reused.
Change: Zero out the entire nopout wqe before sending to fw.
Impact: All

Enhancements
============
1. Feature: Updated the README to remove the jumbo MTU limitation caveat
Impact: All

Version 2.6.2.2b (Nov 09, 2010)
===============================

Fixes
=====
1. Problem: Cont00050725 - RH6.0:iSCSI HBA Linux: bnx2i WARN-CONN_DISCON
timed out message observed when restarting iSCSI service
Cause: A chip panic was observed as CFC delete was initiated without
SRC delete being executed first.
Change: There's a path where if the connect response exceeded the
connection timeout, CFC delete will occur without first
executing SRC delete.
Impact: 5771X

Enhancements
============
1. Feature: Added jumbo MTU support for iSCSI offload connections
Change: For cases where the shost is not provided, jumbo MTU is
not supported.
Impact: All

Version 2.6.2.2a (Oct 28, 2010)
===============================

Enhancements
============
1. Added send text pdu support for iSCSI send-target discovery via the
offload path

2. Added compilation support for RHELS5.6-alpha

3. Reduce the hard-coded 20s delay wait time to 1s for NETDEV_GOING_DOWN
operations

4. Changed the ulp_ops->iscsi_nl_send_msg() to prevent a circular lock
dependency issue

Version 2.6.2.1a (Oct 11, 2010)
===============================

Fixes
=====
1. Problem: Cont00044011 - Linux iSCSI: Cannot obtain max number of sess
when changing sq_size to 16 (5708)
Cause: - Task allocation unit were not correctly allocated
- Offloaded PG were being leaked
- 5706/08 firmware's context allocation were not correct
Change: Fixed all 3 desribed issues above. This also requires
an update of the 5706/08 firmware which contains this fix.
Impact: 570X

2. Problem: Cont00049584 - System panic with this message "mutex_lock"
Cause: The single threaded iSCSI daemon has prevented the NETDEV_UNREG
path to invalidate the host when it is too busy trying to
perform session recovery.
Change: The fix is separated in both the open-iscsi utility and bnx2i.
The fix in bnx2i is to combat netlink messages from being lost.
The fix in the open-iscsi utility is to fix the single threaded
scheduler which flushed the INVALID_HOST path. The patch has
already been submitted to RHELS for the next release of 5.6/6.0.
Impact: 5771X

3. Problem: Cont00049609 - Running iLab automated iSCSI test 6.1 on RHELS6.0
intermittently caused kernel panic
Cause: A bug in the TMF LUN reset command generation code in bnx2i has
corrupted the LUN number which the target will reject the
request. This has led to libiscsi to dereference an incomplete
TMF scsi_cmd; hence the kernel panic.
Change: Fixed the TMF LUN reset generation in bnx2i.
Impact: All

Version 2.1.3a (Sep 15, 2010)
=============================

Fixes
=====
1. Problem: Cont00049899 - RHELS5.5 iSCSI boot thru offload path fails in
IPv6 mode
Cause: The local IPv6 address being transferred to the iSCSI daemon
is corrupted
Change: Fixed the proper formatting of the ipv6 address for the
HOST_PARAM_IPADDRESS retrieval
Impact: All (RHELS5.4/5.5 and IPv6 only)

Version 2.1.2z (Sep 07, 2010)
=============================

Fixes
=====
1. Problem: Cont00049798 - System unresponsiveness during cable pull test
Cause: This is newly introduced by the previous code. The root cause
of the problem relates to how libiscsi immediately initiates
another nopout request when the previous one fails to queue
Change: Allow nopout requests to return success as normal. The
associated task will get freed upon nopout timeout.
Impact: All

Version 2.1.2y (Sept 02, 2010)
==============================

Fixes
=====
1. Problem: Cont00049634 - Linux iSCSI: MC assert on idle port while
running ifup/down with 128 sessions
2. Problem: Cont00049667 - Linux iSCSI: bnx2x_panic_dump while running
adapter selftest with active sessions connected
([bnx2x_stats_update:1070(eth6)]storm stats were not updated
for 3 times)
3. Problem: Cont00049477 - Linux iSCSI: bnx2x_panic_dump while running
adapter selftest with active sessions connected
(bnx2x_cnic_handle_cfc_del:4443)
4. Problem: Cont00049584 - LinuxiSCSI: System panic with this message
"mutex_lock+0x2b/0x50"
Cause: Several issue in connection cleanup and bnx2i_stop() code and
bnx2i was not uploading connection if it does not receives
TCP CONN_DISCON completion. also bnx2i_ep_connect() was not
handling certain error cases well which was resulting resource
leak and also messing up cid and l5_cid handling mapping
Change:
* Moved 'hba->adapter_state' flags bit clear to after connection
cleanup wait is over. This allows ep_disconnect() code to run
normally and upload the connection properly
* Added code to wait for pending connection offload and upload
requests to complete before proceeding to chip clean-up. iscsid
and libiscsi will not cleanup these ep's when session_drop() is
called because these ep's are not yet bound to any iscsi sessions
* Forcefully terminate all in progress connection recovery at the
earliest, either in bind(), send_pdu(LOGIN), or conn_start().
This will avoid iscsid waiting for 10-15-sec waiting for login
response and then proceeding with connection cleanup. This fix
enables iscsid to start connection cleanup process immediately
* There are known certain target TCP stack behavior which could
lead to missing CONN_DISCONNECT request timeout eventhough
firmware has terminated the tcp connection properly. Firmware team
has confirmed it is safe to terminate and CFC_DEL these connections
* Fixed several issues in error handling code in bnx2i_ep_connect()
which could lead to resource leak and cid and iscsi cid mangling

Impact: 5771X

Enhancements
============
None

Version 2.1.2x (Aug 26, 2010)
==============================

Fixes
=====
1. Problem: Cont00049634 - MC assert on idle port while running ifup/down
Cause: The chip panic was caused by performing a CFC deletion
operation to a connection that is not idle. The tx/rx pipe
in the driver were still trying to access the chip.
Change: The tx/rx pipe is now suspended before attempting the
chip cleanup
Impact: 5771X

Version 2.1.2w (Aug 25, 2010)
==============================

Fixes
=====
1. Problem: Cont00049584 - System panic with this message "mutex_lock"
Cause: The single threaded iSCSI daemon has prevented the NETDEV_UNREG
path to invalidate the host when it is too busy trying to
perform session recovery.
Change: Instead of changing the iSCSI initiator code, the NETDEV msg
handling path was modified to prevent the iSCSI daemon from
entering session recovery in the NETDEV_UNREG path.
Impact: 5771X

2. Problem: Cont00049477 - bnx2x_panic_dump while running adapter selftest
Cause: Another CFC delete chip panic was observed when CONN_DISCONN
timeout (option2 disconnect timed out) happens. The driver
should not allow the associated l5_cid from being freed which
will prevent l5_cid reuse.
Change: Block the freeing of the associated l5_cid
Impact: ALL

Version 2.1.2v (Aug 18, 2010)
==============================

Fixes
=====
1. Problem: Cont00049477 - bnx2x_panic_dump while running adapter selftest
Cause: Its a cleanup issue exposed by uIP taking too long to recover
the session. This has led to the driver initiating the chip
cleanup process while the iSCSI daemon is staggering its
connect/disconnect request.
Change: Disallow ep_connect request while performing chip cleanup
Impact: ALL

Version 2.1.2u (Aug 11, 2010)
==============================

Fixes
=====
1. Problem: Cont00049283 - cannot login thru offload path with vlan
Cause: The hardware net device identifier should be used instead of
the vlan identifier
Change: Since this is the intended behavior, only the README has been
updated with this info
Impact: ALL

Enhancements
============
1. Ignore all netevents associated with VLAN. Only process netevents from
the non-VLAN net device

Version 2.1.2t (Aug 08, 2010)
==============================

Fixes
=====
1. Problem: Cont00049208 - Error when compile bnx2i under IA64
Cause: The IA64 architecture does not support cflags of -mhard-float
Change: Since bnx2i does not use any floating point components, it
has been decided to remove both -ffast-math and -mhard-float
from the Makefile
Impact: ALL

2. Problem: Cont00049245 - Session recovery timeout kernel panic
Cause: iscsi_conn was destroyed asychronously after long selftest
Change: Added guard against pointer dereferencing for CONN_DISCONN
conditions
Impact: ALL

3. Problem: Cont00049247 - Kernel panic seen after selftest a few times
Cause: cnic csk was nullified upon chip cleanup from bnx2i stop.
At the same time, a new instance of iscsid tries to disconnect
the same bnx2i endpoint but now with the cnic csk being NULL.
Change: Added guard against double calling of hw_ep_disconnect via
ep->state being EP_STATE_IDLE
Impact: ALL

4. Problem: Cont00049182 - IPv6 redirection does not work on Equalogic
target
Cause: With the new ipv6 enabled uIP, it uncovered a bug in the
ep_poll routine where bnx2i is providing an erroneous timeout
error to the iSCSI daemon.
Change: Fixed the bug in the ep_poll routine
Impact: ALL

Version 2.1.2s (Aug 03, 2010)
==============================

Fixes
=====
1. Problem: Cont00049161 - Kernel panic occurs running iLAB test6_1
Cause: The kernel panic was caused by an synchronization issue in the
iSCSI stack when a fail TMF lun reset request was introduced
by a bug in our driver.
Change: Fix the lun reset TMF request endian bug where the lun field
was not correct
Impact: ALL

Version 2.1.2r (Aug 02, 2010)
==============================

Fixes
=====
1. Problem: Cont00049047 - EP disconnect timeout - chip panic
Cause: Chip panic occurred while trying to force CFC delete upon
cm_abort/close (CONN_DISCONN) timeout
Change: It is adviced to not separate the conn destroy procedure of
SRC_DELETE, terminate offload and CFC_DELETE. So upon a
CONN_DISCONN timeout situation, no CFC_DELETE will be issued.
Impact: 5771X

Enhancements
============
1. Added temporary workaround for the HOST_IPADDRESS parameter for ipv6

Version 2.1.2q (Jul 30, 2010)
==============================

Fixes
=====
1. Problem: Cont00048941 - iscsi2_conn_failure kernel panic due to target
restart
Cause: Kernel panic occurred in iscsi2_conn_failure dereferencing
a NULL iscsi_conn pointer. The asynchronous tcp FIN/RST that
gets received might have been blocked while the iscsi_conn
is being nullified.
Change: Added check against iscsi_conn/sess dereferencing for
asynchronous response such as remote abort/close scenarios
Impact: All

2. Problem: Cont00049068 - Sessions drop and recovery against Lefthand
Networks P4300 target
Cause: The session recovery was caused by the LUN reset timeouts.
Only abort_task TMF is supported.
Change: Added support for other TMF modes like LUN reset.
Added protocol violation fix for NOP-Out responses to
unsolicited NOP-Ins
Impact: All

Version 2.1.2p (Jul 29, 2010)
==============================

Fixes
=====
1. Problem: Cont00049013 - bnx2i_tear_down_conn kernel panic
Cause: Chip panic occurred due to CID reuse without being
initialized
Change: Added chip cleanup procedure in the bnx2i module
unloading code path
Impact: 5771X

Version 2.1.2o (Jul 28, 2010)
==============================

Fixes
=====
1. Problem: Cont00049044 - bnx2i driver version is not correct
Cause: Version didn't get bumped
Change: Updated version string
Impact: ALL

2. Problem: Cont00049047 - EP disconnect timeout
Cause: CONN_DISCONN was causing a double CFC delete request which
ultimately caused the chip to panic
Change: Fixed the double CFC delete request handling
Impact: 5771X

3. Problem: Cont00049857 - System lock up when connect to lefthand target
Cause: Two sess spinlocks were being requested in the NOP-Out
local completion path
Change: Fixed the spinlock request in the handling routine
Impact: All

Version 2.1.2n (Jul 24, 2010)
==============================

Fixes
=====
1. Problem: Cont00048998 - Compilation error found with sles11sp1x86
Cause: The ARCH variable during the compilation was overwritten
with i686 which failed recordmcount.pl
Change: Removed the ARCH variable in the Makefile as it is not used
Impact: ALL

2. Problem: Cont00047900 - bnx2x panic observed after booting via iSCSI
boot
Cause: The previous fix had a bug where the IP ADDRESS was wrong
Change: Fixed the IP ADDRESS bug in the HOST_PARAM
Impact: ALL

Version 2.1.2m (Jul 20, 2010)
==============================

Fixes
=====
1. Problem: Cont00047900 - bnx2x panic observed after booting via iSCSI
boot
Cause: The RQEs were not being freed for unsolicited NOP-Ins
Change: Fixed 2 bugs in the NOP-In handling.
Modified the conn_bind routine to detect and perform a chip
cleanup on the stale endpoints.
Added temporary workaround for the HOST_IPADDRESS parameter
Impact: ALL

Version 2.1.2l (Jul 15, 2010)
==============================

Fixes
=====
1. Problem: Cont00041327 - Need Ability to Identify Adapter iSCSI Offload
Capabilities
Cause: This CQ was resolved in t5.2 but did not work on distro that
uses a single transport name such as SLES11
Change: Modified the driver to examine the iSCSI offload license upon
bnx2i_start. This will prevent the adapter from
appearing in the /sys/class/iscsi_host/hostN entry.
Impact: ALL

Enhancements
============
1. Fixed potential kernel panic caused by stale pointer dereferencing
from elements in the ofld_list whenever cnic fails the ofld request

2. Modified ep_connect/ep_disconnect to guard against asynchronous calls
from the iSCSI daemon during NETDEV_GOING_DOWN->NETDEV_DOWN

Version 2.1.2k (Jun 30, 2010)
==============================

Enhancements
============
1. Added ep_active_list to replace active_sess code
2. Optimized the HOST_PARAM_IP_ADDRESS retrieval code to use
ep_active_list
3. Added module param ooo_enable to enable the TCP out-of-order feature
for iSCSI offload (default = 1)
4. Restored the disconnect timeout for 5771X back to 20s as CONN_DISCON
timeouts were observed

Version 2.1.2j (Jun 18, 2010)
==============================

Fixes
=====
1. Problem: Cont00046648 - CID Leakage occurs while running iLab test 5.12
(connection closure scenarios) rework
Cause: The new bnx2x driver 1.60.24 has changed the max FIN
disconnect timeout down to 6s instead
Change: Modified the disconnect timeout for 5771X back to 10s
Also modified the clean up procedure for the case where the
iSCSI daemon is slow or not operational for bnx2i_stop
Impact: ALL

2. Problem: Cont00044011 - Cannot obtain max number of sessions when
changing sq_size to 16 for 5708
Cause: The driver has capped the number of max commands to sq_size/2
unnecessary
Change: Restored the cmds_max = sq_size instead of num_ccells
Impact: ALL

Version 2.1.2i (Jun 10, 2010)
==============================

Fixes
=====
1. Problem: Cont00046648 - CID Leakage occurs while running iLab test 5.12
(connection closure scenarios)
Cause: Still occurred with the piggybacked FIN on logout responses
Change: Extended the disconnect timeout for 5771X to 20s to accommodate
for the worse case firmware disconnect timeout of 16s
Impact: 5771X

Enhancements
============
1. Correspondingly extended the per connection clean up timeout to 20s

Version 2.1.2h (Jun 04, 2010)
==============================

Fixes
=====
1. Problem: Cont00047973 - 57711E: Kernel panic when running iLab automated
test 6.14 (iProt's delayed logout response)
Cause: The open-iscsi stack's 15s logout timeout has expired and a
disconnect request was forced prior to the delayed logout
response is received. This has created a stale pointer
deferencing in the libiscsi stack
Change: Modified the disconnect path to handle logout req/resp
accordingly. Also suspend the rx endpoint for disconnect
timeout conditions to prevent stale pointer dereferencing in
libiscsi
Impact: 5771X

2. Problem: Cont00046648 - CID Leakage occurs while running iLab test 5.12
(connection closure scenarios)
Cause: Reset completion was received instead of close complete kcqe
while the driver is engaged in connection close request
Change: Modified various graceful/abortive local/remote connection
termination code path for both 1g/10g
This works in conjunction to the new cnic changes
Impact: All

Enhancements
============
1. Added HOST_IP_ADDRESS in sysfs

Version 2.1.2g (May 26, 2010)
==============================

Fixes
=====
1. Problem: Cont00047794 - Linux-iscsi: Everest always terminates the
iSCSI connection (logout) with a reset packet
Cause: The code to decide to perform a graceful vs abortive
termination did not take into account this situation where
a remote close indication happened prior to the locally
initiated termination sequence
Change: Modified the code which decides to perform a graceful vs
abortive termination to account for this scenario
Impact: All

2. Problem: TCP timestamp module param option was removed
Cause: This option was added from T5.2 and have not been submitted
to upstream bnx2i
Change: The option has been added
Impact: All

Enhancements
============
1. Updated README

2. Added tcp_buf_size module param to control TCP Window size setting

Version 2.1.2f (May 24, 2010)
==============================

Fixes
=====
1. Problem: Cont00047901 - Linux-iscsi: Unable to initiate iSCSI connection
with 57712
Cause: There was a bug in the 57712 identifier code
Change: Added fix in the 57712 identifier code
Impact: 57712, 57712E

Version 2.1.2e (May 21, 2010)
==============================

Fixes
=====
1. Problem: Cont00047527 - Linux-iscsi: Kernel panic after manually killing
iscsid process and removing bnx2i/cnic modules
Cause: The problem was caused by a race condition where the iscsid
daemon tries to access the sysfs host entries while bnx2i
is undergoing rmmod.
Change: Return a length of 0 if the bnx2i hba has been freed or when
it has already been unregistered from cnic
Impact: all chipsets

2. Problem: Cont00047734 - Linux-iscsi: Kernel panic after rebooting with
active iSCSI sessions
Cause: The problem was caused by the stop code where the adapter
state was set to down before the iSCSI daemon has a chance to
perform the cleanup.
Change: Added proper cleanup code in the stop routine
Impact: all chipsets

Enhancements
============
1. Added sysfs entry last_active_tcp_port to display the source TCP port
info of the last iSCSI offload connection used. This is a request from
iLab to test OOO.

Version 2.1.2d (May 03, 2010)
==============================

Enhancements
============
1. Added support for 57712

Version 2.1.2c (Apr 30, 2010)
==============================

Enhancements
============
1. Added the feature to return -EBUSY if the offload connection failure
was due to the 2s CFC WAIT for iscsid.

Version 2.1.2b (Apr 22, 2010)
=============================

Enhancements
============
1. Migrated to use the new uIO method for iSCSI offload connections.
2. Removed the obsolete install_usr option (for bnx2id)

Version 1.8.13d (Apr 12, 2010)
=============================

Fixes
=====
1. Problem: Cont00047101 - Linux-iscsi: Switching from offload to non-offload
with OOB iscsi solution on Red hat 5.5 requires extra steps
Cause: same root cause as CQ44503, makefile defines macro to use which
forces driver to use scsi_transport_iscsi2 for RHEL5.4 only.
Change: Update makefile to define __RHEL54_DUAL_ISCSI_STACK__ for both
RHEL5.4 and RHEL5.5
Impact: Only RHEL5.5 distro, all chipsets

Enhancements
============
None

Version 1.8.13c (Mar 19, 2010)
=============================

Fixes
=====
1. Problem: Cont00046658 - CID leakage occurs (submit GRC dump message from
bnx2i driver) while running iLab automated test 1.1
(login/logout)
Cause: 5770x firmware design is changed not to process and complete
TCP_CLOSE RAMROD request after any TCP event (FIN/RST received,
TCP protocol error detected, etc') occured on the connection
Change: This is a big change and we feel there is a finite time delay
(big enough) between iscsi logout w/o piggybacked FIN received
and by the time iscsid issue ep_disconnect() during which target
TCP stack can issue FIN or the RST. By design bnx2i driver issues
TCP_CLOSE on a gracefully terminated iscsi session (using iscsi
logout process) and for all error conditions it will issue
TCP_ABORT request. So the current firmware change cause a big
challenge which cannot be mitigated in the driver. Only way bnx2i
driver can handle is to issue TCP_ABORT for all connection termination
process whether it is graceful or abortive cleanup. This release is
just a partial shutdown which will sucessfully handle iscsi logout
pdu with piggybacked FIN. Further analysis and discussions is on
going with the firmware team.
Impact: 5771x chipset. Please refer to 'Change' section for further limitation
and follow-up issues to be addressed with the firmware team.

2. Problem: Cont00046691 - Linuxiscsi: SUT became unstable and ask to run grcdump
after login/logout
Cause: Duplicate of Cont00046658
Change: Please refer to Cont00046658 for details
Impact: 5771x chipset

Enhancements
============
None

Version 1.8.13b (Feb 04, 2010)
=============================

Fixes
=====
1. Problem: 5771x doorbell page size reduced from 4096B to 128B causing
iSCSI offload to break
Cause: iSCSI doorbell calculation has to be fixed to accomodate this
HSI change
Change: Changed doorbell mapping code to match the HSI
Impact: 5771x chipset

Enhancements
============
Add 57712 PCI ID support

Version 1.8.13a (Jan 20, 2010)
=============================

Version 1.8.12f (Jan 19, 2010)
=============================

Fixes
=====
1. Problem: Cont00044986 - LinuxiSCSI:Unable to get more than a few disks
when i login to Netapp setup with maxlun disks
Cause: In certain configurations kernel is assigning 'shost->max_lun'
a value of '8'. In most configurations is correctly assigned
'512'
Change: Explicitly initialized shost->max_lun to '512' when a new
scsi host is allocated and initialized
Impact: All chips, RHEL5.4 Linux distro

Enhancements
============
None

Version 1.8.12e (Dec 11, 2009)
=============================

Fixes
=====
None

Enhancements
============
Per OEM request made system log entry more administrator friendly
e.g. Changed
"bnx2i: hba ffff810089abdcef does not support iscsi"
to
"bnx2i: dev eth0 does not support iscsi"

README.TXT was updated to reflect this change.

Version 1.8.12d (Dec 09, 2009)
=============================

Fixes
=====
1. Problem: Cont00044503: RHEL 5.4 x86_64 with Multiple iSCSI Errors
Booting the Kernel
Cause: out-of-tree bnx2i was including references to symbols in
scsi_transport_iscsi1 where as iscsi_tcp was referencing the
ones in scsi_transport_iscsi2. This conflict caused software
and offload iscsi not to coexist
Change: Modified bnx2i driver to work with scsi_transport_iscsi2.
Update session/connection/endpoint setup/teardown code path
to account for new data structure objects created in libiscsi2
which were not present in libiscsi1
Impact: All chips, RHEL5.4 Linux distro

Enhancements
============
None

Version 1.8.12c (Dec 01, 2009)
=============================

Fixes
=====
1. Problem: Cont00041327: Linux: Need Ability to Identify Adapter
iSCSI Offload Capabilities
Cause: OEM's requested this feature because the driver was
registering all NX2 devices with the iscsi transport layer.
Change: Modified bnx2i to register only the licensed devices with
iscsi transport layer. This will avoid the need for mechanism
to identify licensed and unlicensed NX2 devices as only the
licensed devices will appear in '/sys/class/iscsi_transport'
directory.
Impact: All chips, All Linux distro

Enhancements
============
None

Version 1.8.12b (Nov 09, 2009)
=============================

Fixes
=====
1. Problem: Async logout with Equallogic target results in
"CONN_DISCON" and "CONN_CLEANUP" timeout messages
Cause: This issue was initially reported by Vmware against
ESX4.5 iSCSI inbox driver. This same issue was reproduced
in Linux as well. Driver was returning DID_NO_CONNECT when
the session is being logging out which caused a ton of debug
log from SCSI-ML. While running heavy I/O on 12 session per
port and simultaneously issue async message to logout these
sessions caused a huge log spew which caused 570x device
interrupt to be delayed in order of 10x seconds.
Change: Return DID_HOST_BUSY while session is being logged out and
till either session recovers or recovery times out. Once
session recovery timeout is hit driver will return
DID_NO_CONNECT
Impact: All chips, All Linux distro

Enhancements
============
Repacking 1.8.9u as baseline for T5.2 release

Version 1.8.9u (Oct 16, 2009)
=============================

Fixes
=====
1. Problem: Cont00044141 - Linux iSCSI: Kernel panic while performing
cable pull test with MPIO on RHEL5.4 (swiotlb_map_sg+0x2f/0x14a)
Cause: swiotlb_map_sg() crash was caused because SCSI-ML queued a
command with sg_length = 0, sg_count = 1 and sg table != NULL.
Driver was only looking at last 2 parameters to call pci_map_sg()
or not. Follow on issue was cause by open-iscsi daemon changes,
ep_disconnect() was called without calling stop_conn().
Change: Fixed driver to consider 'sg_length' before mapping SG buffers &
also shost workqueue is flushed in ep_disconnect() if it is not
already done so.
Impact: All chips on RHEL5.4

Enhancements
============
None

Version 1.8.9t (Oct 08, 2009)

Enhancements
============
Special sections were added to list know issues and workarounds related
to out-of-tree bnx2i and software iscsi coexistence issue in RHEL5.4

Version 1.8.9s (Sept 30, 2009)
=============================

Fixes
=====
1. Problem: Cont00043901 - Linux iSCSI: RHEL5.4 OOB - Kernel panic
during logout with iscsi-initiator-utils-6.2.0.871-0.10c
Cause: Latest open-iscsi changed graceful session tear down sequence.
ep_disconnect() is called before stop_conn() and this caused
NULL pointer access while dereferencing conn->ep
Change: check for 'conn->ep' validity before dereferencing
Impact: All chipsets, RHEL5.4 only

2. Problem: Cont00043896 - Linux iSCSI: System crash with
iscsi-initiator-utils-6.2.0.871-0.10c
Cause: Duplicate of CQ43901. Please check CQ43901 for root cause
Change: Same as CQ43901
Impact: All chipsets, RHEL5.4 only

Enhancements
============
1. Problem: Cont00041327 - Linux: Need Ability to Identify Adapter
iSCSI Offload Capabilities
Cause: Refined fix which caused unlicensed device not to be
unregister with iscsi transport. This is a partial fix and
needs interface to be up before bnx2i loads.
Complete fix will be delivered in T5.2
Change: Check for cnic_dev->mac_iscsi_conn while the device is
registered as this value will be cleared during
unregister_device() call
Impact: All chipsets, Linux

Version 1.8.9r (Sept 27, 2009)
=============================

Fixes
=====
1. Problem: Cont00041327 - Linux: Need Ability to Identify Adapter
iSCSI Offload Capabilities
Cause: bnx2i cannot determine license information unless the
device is registered with cnic and the network port is
initialized by the user (ifup). Because of limitation,
driver was registering transport name for all enumerated
NX2 devices
Change: Driver will continue to register all devices at init time
and unregister the transport name when license information
is available and found the device is not licensed for iSCSI.
This eliminates the need for a separate means to identify if
device support iSCSI or not.
Impact: All chipsets, Linux

Version 1.8.9q (Aug 31, 2009)
=============================

Fixes
=====
1. Problem: Cont00043282 - linux:iscsi_offload:can not modporbe bnx2i after
installation of linux-nx2 v5.2.6 on RH 5.4
Cause: RHEL5.4 has 2 sets of scsi_transport_iscsi and libiscsi modules,
second modules added specifically to support inbox bnx2i. With
the current service load order, scsi_transport_iscsi2 gets
loaded before bnx2id service is started. Initially bnx2id was
chosen to be loaded after network service is started because of
dependency of bnx2/bnx2x. Now that cnic driver implements weak
symbol linking with bnx2/bnx2x, we can load cnic, bnx2i modules
(start bnx2id service) much before network service
Change: start bnx2id service before iscsi/iscsid services
Impact: All chipsets, Linux

Version 1.8.9o (Jul 25, 2009)
=============================

Fixes
=====
1. Problem: Cont00042502 - Linux iSCSI HBA: SUT kernel panics after test
I/O is started
Cause: MPP driver failed to honor bnx2i's 'sg_tablesize' and
'max_sectors' parameter causing bnx2i to overstep BD table memory.
Change: Workaround is to allocate 4KB of memory for each BD table, i.e.
255 entries per table which is sufficient to handle a maximum
IO size of 512KB issued by MPP
Impact: All chipsets, Linux

Enhancements
============
Above change will cause bnx2i to consume little more memory than previous
drivers

Version 1.8.9n (Jul 22, 2009)
=============================

Fixes
=====
1. Problem: Cont00042555 - Kernel panic occurs while running iLab iSCSI
automated test 6.4 (data digest error)
Cause: Some tests used to hang because session recovery code never
returned from wait due to sess->recovery_state mis-match
Change: Fixed wait state variable to check for sess->recovery_state = 0,
which is cleared when session is re-logged in

Version 1.8.9l (June 30, 2009)
=============================

Fixes
=====

1. Problem: DMA memory leak and eventualy run out of memory during
overnight test
Cause: wrong 'size' parameter is sent to pci_free_consistent()
Change: pass 'dma->size' instead of PAGE_SIZE as 2nd argument to
pci_free_consistent()
Impact: All chipsets, Linux, ESX

2. Problem: Linux iSCSI: Soft lockup seen while continuously restarting
iscsid service overnight with persistent targets attached
(bnx2i_conn_stop+0xc8/0x109)
Cause: login resources allocation failure was not handled correctly
in create_conn() which caused timer_del_sync() to be called
on an uninitialized timer in destroy_conn() path.
Change: fixed code to handle return value of
bnx2i_conn_alloc_login_resources() and also added a flags to
track if conn->poll_timer is initialized or not.
Impact: All chipsets, Linux, ESX

3. Problem: Everest1.0:Linux iSCSI:CX4 - kernel panic while running IPv6
login/logout maxsessions stress(bnx2i_cm_remote_abort+0x23/0x41)
Cause: open-iscsi does conn_stop()/conn_destoy()/ep_disconnect()/
sess_destroy() in the same order. So if remote RST/FIN is
received after conn_destoy() will cause panic because driver
will try to access ep->conn->worker_enabled and ep->conn is
already set to NULL in conn_destoy(). We found the same issue
on another test bed last evening
Change: Check ep->conn in cnic upcalls for remote RST/FIN and do not
start session recovery if 'ep->conn' is NULL. Also take sess->lock
to synchronize remote RST/FIN and conn_destroy() accessing ep->conn
Impact: All chipsets

Version 1.8.9i (May 26, 2009)
=============================

Fixes
=====

1. Problem: Cont00039906 - Linux iSCSI: Soft lockup seen when performing
adapter selftest with more than 10+ sessions connected
Cause: bnx2i was taking spinlock before calling cnic->register_device()
and cnic would call bnx2i_start() in the same context which
actually will sleep waiting for ISCSI_INIT response
Change: Fix is not to hold spinlock for the duration of register_device()
Impact: All chipsets, Linux, ESX

2. Problem: Cont00041210 - Everest1.0:Linux iSCSI:CX4 - kernel panic while
running heavy disk traffic with bnx2i v1.8.7
(bnx2i_conn_main_worker+0x10b/0x70a)
Cause: There were several bug fixes to workqueue/tasklet in last week
and this panic dump is addressed by it
Change: Changes made to support tasklet implementation for ESX broke
some of the logic. Cleaned up a bunch of issues related to this
Impact: All chipsets, Linux, ESX

Enhancements
============
More stable ESX code with tasklet implementation and enhanced
task management code. Build 00005 is based on this code. Some of the
tasklet and workqueue bug fixes are applicable to both ESX and Linux

Version 1.8.7 (May 13, 2009)
=============================

Fixes
=====
1. Problem: Various driver crashes in error recovery path
Cause: tasklet/workqueue are scheduled when connection
is in stopped state.
Change: Not to accept any commands if conn_stop() is called on
the connection and this will eliminate any tasklet/workqueue
scheduling. This was initially reported and more often seen
in ESX, but same problem exhists in Linux as well
Impact: All chipsets, Linux, ESX

Enhancements
============
Further enhancements to tasklet/workqueue code

Version 1.8.6 (May 11, 2009)
=============================

Fixes
=====
1. Problem: Cont00040971 - iSCSI Boot Linux Offload:NX2: compile error
with bnx2i v1.8.5 on SuSE 10 SP2
Cause: In order to support older kernel iscsi_compat.h defines some
functions which should have been defined 'static' but are not.
This creates trouble when scsi_transport_iscsi.h is included in
multiple *.c files.
Change: worked around iscsi_compat.h header file issues
Impact: All chipsets, SLES10 SP2

2. Problem: Cont00040921 - ESX4.0 build 4.0.0-00000_x86_64 w/ bnx2i -
iscsi_cmd_win_closed
Cause: not conforming to rfc1982
Change: Fixed serial arithmetic logic as per rfc1982
Impact: ALL chipsets, Linux, ESX

3. Problem: Cont00040512 - ESX4.0 build 4.0.0-00000_x86_64 w/ bnx2i -
Disks disappear after overnight stress tests
Cause: tasklet was being scheduled without being enabled when connections
goes into recovery mode
Change: Tasklet is disabled in stop_conn() and enabled in bind_conn()
Impact: All chips + ESX40U1

4. Problem: Cont00040920 - ESX4.0 build 4.0.0-00001_x86_64 w/ bnx2i -
bnx2i_process_new_cqes+0x7b
Cause: This issues is seen only in workqueue implementation for ESX as
scsi_host workqueue was not flushed fearing it would affect
other connections. But would cause work to be scheduled after
connection is torn down or in middle of recovery process
Change: per connection tasklet implementation will not exhibit this
failure as tasklet is disable in conn_stop() and re-enabled in
conn_bind()
Impact: All chipsets, ESX40U1

5. Problem: Cont00040918 - ESX4.0 betabuild 4.0.0-00001_x86_64 w/ bnx2i
Cause: Duplidate of Cont00040920, please refer to Cont00040920 for
more details
Change: Duplidate of Cont00040920, please refer to Cont00040920 for
more details
Impact: All chipsets, ESX40U1

Enhancements
============
ESX40U1 driver changes to use tasklet instead of workqueue for command
transmission and CQE processing.

Version 1.8.5 (Apr 29, 2009)
=============================

Fixes
=====
None

Enhancements
============
ESX40U1 driver changes to match the updated iscsi_net API's

Version 1.8.4 (Apr 29, 2009)
=============================

Fixes
=====
1. Problem: Connection setup problems with 570x
Cause: Changes to 570X_SQE_DEFAULT macro caused alternate connections
to fail
Change: reverted back 570X_SQE_DEFAULT to 128
Impact: 5706/5708/5709

Enhancements
============
Performance improvements mentioned above

Version 1.8.3 (Apr 26, 2009)
Version 1.8.2 (Apr 25, 2009)
=============================

Fixes
=====
None

Enhancements
============
Vmware ESX40U1 driver updates

Version 1.8.1 (Apr 25, 2009)
=============================

Fixes
=====
1. Problem: Cont00040099 - Linux iSCSI T4.6+ 57710 performance bottleneck
at 80K IOps (L2 and Offload)
Cause: CQE processing in softIRQ context was becoming bottleneck because
5771x has only on MSI-X vector for iSCSI completion notification.
This caused 1 core to be pegged 100% processing completions.
Change: Implemented a per connection workqueue to process both command
request and completion. This spreads work load to across available
cores and boosted IOPS numbers to nearly at par with what should be
Impact: 57710/5771/57711E

Enhancements
============
Performance improvements mentioned above

Version 1.8.0 (Apr 22, 2009)
============================

Fixes
=====
1. Problem: Cont00040267: Linux iSCSI: Kernel panic during cable pull
with one iSCSI over native TCP connection + iSCSI offloaded
connection
Cause: iscsi daemon is calling iscsi_transport->ep_poll() with
ep_handle=0xffffffff eventhough driver failed ep_connect()
request. This causes ep_poll() to access invalid memory and
cause the crash
Change: Add additional check to ignore both ep_handle = 0xffffffff and
null pointer
Impact: 5706/5708/5709/57710/5771/57711E

Enhancements
============
changed pci dma memory management code to be more stream lined

Version 1.7.0 (Mar 17, 2009)
============================

Fixes
=====
1. Problem: Cont00039999 - Linux iSCSI: Usages count increases for bnx2x
when iSCSI sessions are connected via Teton/Xinan devices
Cause: Before looking up the route to target IP, there is a requirement
that bnx2i has to register with cnic all active devices. cnic
won't identify the device if the device is not registered.
So when the first connection is offloaded, bnx2/bnx2x module
usage count will be incremented once for every corresponding
NX2 device in the system even though connection is offloaded on
only one. This usage counts will be later decrement to zero when
the last connection is torn down.
Change: Fix is the unregister all idle devices before returning from
ep_connect()
Impact: 5706/5708/5709/57710/5771/57711E

2. Problem: Cont00040037 - Linux iSCSI: Need jumbo frame support for
Linux iSCSI offload in T5.0
Cause: bnx2i was checking and not allowing connection offload is device's
MTU is set to > 1500
Change: changed maximum MTU limit to 9000B
Impact: 5706/5708/5709/57710/5771/57711E

3. Problem: Cont00039906 - Linux iSCSI: Soft lockup seen when performing
adapter selftest with more than 10+ sessions connected
Cause: Multiple problem caused this issue - big connection teardown/
cleanup timeout in bnx2i and bnx2 was swutching off interrupts
before propogating stop() call to ULPs
Change: bnx2 driver code was reordered to keep interrupts enabled during
ULP's stop() call and bnx2i driver timeouts are tuned based on
device type
Impact: 5706/5708/5709

4. Problem: Cont00039648 - Linux iSCSI: Please add line in README.TXT that
states ipv6.ko is a requirement for cnic to load
Cause: Documentation enhancement request
Change: updated README.TXT to reflect the dependency requirements
Impact: 5706/5708/5709

Enhancements
============
None

Version 1.6.2 (Mar 10, 2009)
============================

Fixes
=====
1. Problem: Cont00039912 - Linux iSCSI accel - unable to offload on NC532i,
says iSCSI not supported
Cause: mismatch in PCI Id definition between system include and driver
source
Change: fixed the mismatch
Impact: 57711/57711E

Enhancements
============
None

Version 1.6.1 (Feb 23, 2009)
============================

Fixes
=====
1. Problem: Performance on 5606/5708 is sluggish & session keeps recovering
Cause: 5706/5708 firmware can only handle 172 CQ entries and Everest
requirements of SQ/CQ to be integral number of pages was causing
this issue and 570x family has no such requirements
Change: Execute SQ/CQ size massaging code for 5771X device type only
Impact: 5706/5708

Enhancements
============
None

Version 1.6.0 (Jan 14, 2009)
============================

Fixes
=====
1. Problem: Cont00038728 - Linux iSCSI:Everest:A1: iscsiadm becomes
unresponsive if wrong transport name is used
Cause: There was a list corruption in open-iscsi daemon code caused
when list element is blindly initialized when it is actually
a node in the pend_list. Also conn->link was not initialized
when bind_conn() failed which caused crash in destroy_conn()
code path.
Change: Fixed both open-iscsi user daemon and driver issues
Impact: 57710/57711E

Enhancements
============
Updated copyright information

Version 1.4.9 (Jan 03, 2009)
============================

Fixes
=====
1. Problem: CQ38744 - Everest1.5:Linux iSCSI:CX4 - Unable to connect
to more than ~450 sessions, out of host memory
Cause: Linux kernel can only address 1G memory which includes
all kernel code and data structures. This limitation would
not allow us to offload 1024 iscsi connections
Change: Limit number of outstanding tasks (SQ size) per connections
to 64
Impact: 57711E

Enhancements
============
None

Version 1.4.8 (Dec 31, 2008)
============================

Fixes
=====
1. Problem: CQ38744 - Everest1.5:Linux iSCSI:CX4 - Unable to connect
to more than ~450 sessions, out of host memory
Note: This is 1 of 3 fixes made to support 1024 connections.
Refer to bnx2i-1.4.7 & netxtreme2-1.8.2c_1.48.7 release notes
for other changes
Cause: 992 connections limitation was due to limit on max numbers of
file descriptors 'bnx2id' application was allowed to open.
Default value is 1024, so bnx2id was able to allocate 1023
socket structures and last 31 were not even delivered because
the daemon was unable to open char device to issue ioctl.
So driver ended up with only 992 tcp ports.
Change: Modified application to change RLIMIT_NOFILE parameter to 1056.
With this change we were able to successfully open 1024 connections
using 57711E device on a x86_64 system
Impact: 57711E

Enhancements
============
Updated rc script to create '/dev/bnx2i' node during startup

Version 1.4.7 (Dec 29, 2008)
============================

Fixes
=====
1. Problem: Unable to allocate endpoint structure for 513th connection
Cause: Driver was allocating a total of 512 endpoint structures due
to a macro definition
Change: defined ISCSI_MAX_ADAPTERS to 8
Impact: 57711E

Enhancements
============
None

Version 1.4.6 (Dec 22, 2008)
============================

Fixes
=====
1. Problem: Cont00038965 - Everest1.5:Linux iSCSI:CX4 MF- bnx2i cid
TCP errors while running iSCSI + netperf stress traffic
Cause: queuecommand() would report device offine when
sess->lead_conn->ep is NULL. But actually this value will
be NULL between the time existing endpoint (EP) is cleaned and
a new endpoint is bound in bind_conn() call. This is a valid
transient state during connection recovery and driver is
suppose to report BUSY and not NO_CONNECT
Change: reverted back to old scheme
Impact: 5706/5708/5709/57710/57711

Enhancements
============
None

Version 1.4.5 (Dec 17, 2008)
============================

Fixes
=====
1. Problem: Driver crash when interface IP address is changed while
there are actice connection
Cause: spinlock contention
Change: fixed spinlock contention
Impact: 5706/5708/5709/57710/57711

Enhancements
============
None

Version 1.4.4 (Dec 11, 2008)
============================

Fixes
=====
1. Problem: Cont00038936 - LinuxiSCSI: bnx2x Firmware crash dump when
loging out of EMC target
Cause: Incorrect handling of TCP CONNECT failure caused iscsid to
behave improperly with follow on connections, ep_disconnect()
was getting called just 1-sec after ep_connect(). According to
implementation it should wait 15-secs before timing out,
while firmware times out in 9-secs (3 attempts at 3-sec
interval). So driver doesn't expect ep_disconnect() to be called
before 10-secs after ep_connect() returns
Change: Fixed handling of TCP CONNECT failure in driver which avoids
'iscsid' to get into weird state. Also even though ep_disconnect()
is called immediately, driver will wait for firmware to complete
TCP_CONNECT request with either good or failed status before going
ahead with connection cleanup
Impact: 5706/5708/5709/57710/57711

2. Problem: Cont00038965 - Everest1.5:Linux iSCSI:CX4 MF- bnx2i cid
TCP errors while running iSCSI + netperf stress traffic
Cause: Recently changed queuecommand() to report device office
if session is not in FFP stage. Actually we have to report
device offline only after session recovery timeout (120-secs)
is reached
Change: reverted back to old scheme
Impact: 5706/5708/5709/57710/57711

Enhancements
============
None

Version 1.4.3 (Dec 09, 2008)
============================

Fixes
=====
1. Problem: Cont00038871 - Everest1.5:Linux iSCSI:CX4 MF-
CONN_DISCON timeout + bnx2x driver assert during cable pull test
Cause: Due to open-iscsi interface change, NOOP OUT was not working as
expected. open-iscsi user stack added following connection
params to determine if NOOP is supported in user daemon or
the kernel driver -
1. ISCSI_PARAM_PING_TMO
2. ISCSI_PARAM_RECV_TMO
As bnx2i depends on iscsid to implement this feature, it should
return -ENOSYS to set_param() call to update above said parameters.
Change: After implementing this change, iSCSI NOOP OUT started to behave
as expected.
Impact: 5706/5708/5709/57710/57711

2. Problem: Cont00038797 - LinuxiSCSI:Segmentation fault when running
ifup/down and passing traffic
Cause: Partly caused by NOOP OUT issue explained above (Cont00038871)
and other issue was not guarding 'active_sess' list while
traversing in bnx2i_start_hba_shutdown() routine & not
properly handling in-recovery state in TMF code path
Change: Fixed above said conditions
Impact: 5706/5708/5709/57710/57711

Enhancements
============
None

Version 1.4.2 (Dec 03, 2008)
============================

Fixes
=====
1. Problem: Everest1.5:Linux iSCSI:CX4 - bnx2x driver assert while changing
MTU size with targets connected
Cause: Issue was cause by mutex lock deadlock condition in
cnic when unregister_device() is called while bnx2i is still in
cnic_stop() function call processing.
Change: This issue is worked around in bnx2i by deferring inactive device
unregistering till all the connections are torn down
Impact: 57711

Enhancements
============
None

Version 1.4.1 (Nov 17, 2008)
============================

Fixes
=====
1. Problem: Cont00038537 - Everest 1.5E MF-Linux iSCSI:
Unable to iSCSI login to target
Cause: bnx2i was requesting a large number of TCP ports
than bnx2id can allocate.
Change: bnx2i is changed to request 32 TCP ports at a time.
Eventually bnx2id will be fixed to handle socket()/bind()
call failure
Impact: 57711

Enhancements
============
Added support for 57711

Version 1.4.0 (Nov 14, 2008)
============================

Fixes
=====
None

Enhancements
============
Added support for 57711

Version 1.3.11 (Nov 12, 2008)
=============================

Fixes
=====
1. Problem: Cont00038195 - LinuxiSCSI:Bnx2x kernel panic when running
read/write test or when the target became unaccessible
Cause: There was a possibilty driver will unregister with cnic before
all the connections are cleaned up. For such connection only
driver resources are freed in ep_disconnect(). Driver assumes
chip will be reset when ifdown request is completed and this
is true for 5706/5708/5709. However in case of 57710 certain
blocks such as CFC/SEARCHER will not be reset if second port
is up.
Change: So driver will have to wait for all connections to cleanup
before returning from NETDEV_GOING_DOWN notification. Also
driver will block scsi host before entering clean mode to
avoid any futher scsi command being queued with the driver
Impact: 57710

2. Problem: Cont00038030 - LinuxiSCSI: Data corruption writing to iscsi
target
Cause: In Couple of scenarios driver was accessing memory immediately
after freeing. Also in wrong memory was cleared because of wrong
array index (control bits of ITT was not cleared in case of
aborted commands. This would cause when a write command is aborted)
Change: Rearranged memory resources freeing and cleaned ITT table indexing
code
Impact: 57710

Enhancements
============
Enforce max SQ size of 128 for 5706/5708/5709 devices and also adjust
to power of 2.

Version 1.3.10 (Oct 28, 2008)
=============================

Fixes
=====
None

Enhancements
============
Update RPM dependency in bnx2i.spec file from NetXtremeII to netxtrem2

Version 1.3.9 (Oct 28, 2008)
=============================

Fixes
=====
None

Enhancements
============
Fixed a race condition causing kernel dump when a netdev/inet event
is received while session is being torn down. Durning iscsi session
tear down process, open-iscsi stack will execute tasks in following
order -
1) iscsi logout
2) destroy iscsi connection
3) tear down endpoint (TCP connection)
4. destroy iscsi session

This issue will manifest when a netdev/inet event is received b/w
#2 and #4

Version 1.3.8 (Oct 26, 2008)
=============================

Fixes
=====
None

Enhancements
============
Updated RPM spec file to reflect module dependency to NetXtemeII
instead of bnx2/bnx2x

Version 1.3.6 (Oct 16, 2008)
=============================

Fixes
=====
1. Problem: Cont00037814 - Linux iSCSI:Everest:A1: Kernel panic when
running dt during max sessions test
(cnic:cnic_get_bnx2x_ctx+0x59/0x6e)
Cause: Couple of issues attributed to this issue,
1. bug in ep structure handling code in bnx2i driver
2. memory corruption due to boundary over stepping in
bnx2x driver (fixed in 1.46.9)
Change: revamped endpoints offload / destroy list handling code
Impact: 57710

2. Problem: Cont00037858 - Linux iSCSI:Everest:A1: bnx2i: ofld_timer:
CONN_DISCON timeouts when running login/logout continuously
to max number of sessions
Cause: bug in ep offload / destroy list handling code in bnx2i driver
Change: revamped endpoints offload / destroy list handling code
Impact: 57710

3. Problem: Cont00037701 - LinuxiSCSI:EverestA1: Kernel Panic whe running
traffic on both ports
Cause: same as Cont00037814
Change: see Cont00037814 above
Impact: 57710

Enhancements
============
Updated driver logs section in README.TXT

Version 1.3.5 (Oct 06, 2008)
=============================

Fixes
=====
1. Problem: Cont00037576 - Linux iSCSI:Everest:A1: Unable to connect
to more than 64 sessions per port
Cause: With 8 pages limit driver was able to allocate only 72 endpoint
structures.
Change: Doubled number of pages used for endpoint structures to 16
Impact: 57710

2. Problem: Test 5.9 failure with kernel panic
Cause: Incorrect handling in error path was causing SCSI-ML to
free device resources while some commands are still active.
Thus causing kernel panic when driver tried to unmap SG list
at a later point in time
Change: cleaned up session recovery path and cleanup active command list
in case host_reset() failed.
Impact: 57710

Enhancements
============
Increased TCP CLOSE timeout to 20-secs from 10 -secs to be in sync with
firmware limits

Version 1.3.4 (Sept 26, 2008)
=============================

Fixes
=====
1. Problem: Cont00037386 - Linux iSCSI: Installing drivers via
source tarball will not create a bnx2id startup script
Cause: Previous release was partially fixed and user still
need to run 'chkconfig' to get it to work
Change: Added 'chkconfig' to fix the issue properly
Impact: 5706/5708/5709/57710

2. Problem: Cont00037576 - Linux iSCSI:Everest:A1: Unable to connect
to more than 64 sessions per port
Cause: It was hardcoded in header file
Change: Fixed code to limit 64 simultaneous iscsi connection on
5706/5708/5709 and 128 connection on 57710
Impact: 57710

Enhancements
============
Increased num outstanding tasks (SQ size) to 256 for 57710. 570x still
has SQ size of 128

Version 1.3.3 (Sept 22, 2008)
=============================

Fixes
=====
1. Problem: Cont00037386 - Linux iSCSI: Installing drivers via
source tarball will not create a bnx2id startup script
Cause: In previous release only carried partial fix by installing
only the binary, 'bnx2id' and not the init script
Change: updated makefile to copy init script along with 'bnx2id' binary
when 'install_usr' build target is issued. This was initially
fixed in 1.2.12 and got omitted in later releases
Impact: 5706/5708/5709/57710

Enhancements
============
Added debug prints in ep_connect() and ep_disconnect() code path to
easily identify option-2 related issues

Version 1.3.2 (Sept 14, 2008)
=============================

Fixes
=====
None

Enhancements
============
1) Inserted BUG_ON() to trap TCP disconnect timeout
2) Turned off TCP timestamp and fixed receive window to 256K
3) Added code to replenish RQ buffers before issuing any iscsi requests

Version 1.3.1 (Aug 07, 2008)
=============================

Fixes
=====
1. Problem: Cont00035910 - LinuxiSCSI:Kernel panic when running
login/logout with 64 sessions
Cause: iop mapped memory for connection doorbells was not
unmapped and also a small piece of memory was not freed.
This caused a slow memory leak and eventually system would
run out of memory
Change: Fixed memory leak issue
Impact: 5706/5708/5709

Enhancements
============
Updates README.TXT file to add 'iface' usage with examples.
Fixed a critical corruption issue caused by memset() while clearing
SQ/RQ/CQ page table for 57710 devices, failed to adjust actual size
of page table which starts at an offset of DB structure size from
the base address.

Version 1.2.14 (June 20, 2008)
=============================

Fixes
=====
None

Enhancements
============
Updates README.TXT file to clarify Broadcom iSCSI Offload software suite
loading process. Fixed init rc script to manually unload bnx2i and
cnic driver when bnx2id service is stopped. Earlier we would do
'modprobe -r' which could potentially unload bnx2 module and even bring
the network interface down. 'service bnx2id stop' is only intended to
unload iscsi(storage) modules, keeping networking components intact.

Version 1.2.13 (June 19, 2008)
=============================

Fixes
=====
1. Problem: Cont00035285 - DF216309: Open iSCSI Initiators Not Provided for
RHEL5.2 and SLES10.2
Cause: This was caused by interface change resulted in changes in
iscsi transport. This caused a data structure to be referenced
after being freed.
Change: Fixed session teardown code take care of this interface change
Impact: SLES10 SP2 and 5706/5708/5709

Enhancements
============
Removed all references to 57710 in README.TXT file and going forward
Broadcom will release single iscsi-initiator package for Redhat EL 5.0,
5.1 and 5.2

Version 1.3.0 (June 02, 2008)
=============================

Fixes
=====
None

Enhancements
============
Complete support for 57710 added

Version 1.2.12 (May 23, 2008)
=============================

Fixes
=====
1. Problem: Cont00035452 - Linux iSCSI: Installing drivers via source
tarball will not create a bnx2id startup script
Cause: In previous release only carried partial fix by installing
only the binary, 'bnx2id' and not the init script
Change: updated makefile to copy init script along with 'bnx2id' binary
when 'install_usr' build target is issued
Impact: 5706/5708/5709

Enhancements
============
None

Version 1.2.11 (May 22, 2008)
=============================

Fixes
=====
1. Problem: Cont00035451 - Linux iSCSI: Typo in line 29 of bnx2id
startup script
Cause: typo
Change: fixed the comment line in code
Impact: 5706/5708/5709

2. Problem: Cont00035292 - Unnecessary Set Group ID Permission in
bnx2i Source
Cause: file permissions got changed unintentionally
Change: set correct file permissions for source code files
Impact: 5706/5708/5709

3. Problem: Cont00035452 - Linux iSCSI: Installing drivers via source
tarball will not create a bnx2id startup script
Cause: not implemented
Change: added 'install_usr' command to Makefile and document the
required steps in README text
Impact: 5706/5708/5709

Enhancements
============
None

Version 1.2.10 (May 14, 2008)
=============================

Fixes
=====
1. Problem: Cont00035222 - DF215961: Cannot Compile bxn2i-1.2.8 on SLES10sp2
Cause: SLES10SP2 back ported create_session() to include 2 additional
arguments and thus causing minor compilation warning. Also it
would create problems when use attempts to establish an
iscsi connection
Change: Modified makefile to detect number of argument to create_session
by looking at function prototype in header file,
include/scsi/scsi_transport_iscsi.h
Impact: 5706/5708/5709, uses 'awk' to parse the header file efficiently

Version 1.2.9 (May 08, 2008)
============================

Fixes
=====
1. Problem: Cont00035222 - DF215961: Cannot Compile bxn2i-1.2.8 on SLES10sp2
Cause: Similar to Cont00035035, but SLES10 update 2 back ported
scsi_set_resid & scsi_get_resid and placed them in
include/scsi/iscsi_compat.h whereas RHEL 5.2 put them in
include/scsi/scsi_cmnd.h
Change: Modified makefile to accommodate these differences
Impact: 5706/5708/5709

2. Problem: Cont00034621 - Linux iSCSI Xinan: Multiple iSCSI sessions
occasionally do not recover after cable pull
Cause: Sending TCP_RESET KWQE on a connection for which option-2 connect
was not initiated (TCP_CONNECT 1/3) caused neighboring iscsi
connection context memory to corrupt
Change: bnx2i will not issue cm_abort() if option-2 connect was not
successful, it will directly send request to destroy the context
Impact: 5709

3. Problem: Cont00034872 - Linux iSCSI Xinan: Target does not recover
when running MPIO over both Xinan ports
Cause: duplicate of Cont00034621
Change: See Cont00034621 for details

Version 1.2.8 (May 02, 2008)
============================

Fixes
=====
1. Problem: Cont00034848 - Linux iSCSI Xinan: No network activity
(possible chip lockup) after running pqa script
(test 6.1-- Errors from initiator to target) in
a loop using IPv6.
Cause: wrong ITT was posted with login request causing 5709 firmware
to hang. This was caused because upper 2-bits weren't clearing
before putting aborted SCSI WRITE command's ITT to free list.
Same issue won't happen if aborted command was a SCSI READ,
because command type field is '0' for read commands. Also
normal scsi completion won't suffer the same as driver clears
this field before starting completion processing
Change: Driver clears command type fields whenever freeing an ITT value
Impact: 5709

2. Problem: Cont00035035 - DF214119: bnx2i-1.2.7 Fails to Compile on
RHEL5.2-snapshot6
Cause: Newer Linux api functions, scsi_set_resid() and scsi_get_resid()
were back ported to 2.6.18-88 kernel in RHEL5.2 resulting in
compilation errors because of duplicate definitions
Change: worked around in make file. This is a tricky issue caused by
distro's backporting newer features back to older kernels.
This causes following scenario -
1. RHEL 5.1 kernel 2.6.18-53 does not define these functions
2. RHEL 5.2 kernel 2.6.18-88 does define these functions
3. kernels 2.6.19.x to 2.6.22.x does not define it
4. kernel 2.6.23.x+ is part of kernel by default
This makes it hard as it can't be determined whether to define
ourselves or use kernel api's based on linux version as
LINUX_VERSION takes into account only first 3 bytes out of
2.6.x-y. We counter this by greping for function prototypes
in the include directory and based on grep result define macros
which facilitates either local definition or references the kernel
api's
Impact: 5709

3. Problem: Cont00034274 - Linux iSCSI: Running heavy stress on multiple sessions
causes connection resets and other errors
Cause: duplicate of Cont00034848
Change: duplicate of Cont00034848
Impact: 5709

4. Problem: Cont00034977 - B57DELLCDT447 Contains Two Different Open iSCSI
Packages for RHEL5
Cause: Two open-iscsi packages are for RHEL5.0 and RHEL5.1
Change: updates README text file to reflect the importance of two RHEL
related open-iscsi packages
Impact: NA

5. Problem: Cont00035034 - DF213523: Offload Driver (bnx2i) not getting installed
on RHEL5.2
Cause: Duplicate of Cont00035035, package manager was not able to install
the driver because non was built due to compilation error
Change: Duplicate of Cont00035035, package manager was not able to install
the driver because non was built due to compilation error
Impact: NA

Enhancements
============
User will be able to compile and install bnx2i on RHEL5.2, but would like
to remind users/OEMs that RHEL5.2 does not feature in supported distributions
list for this release and only minimal validation is achieved.

Version 1.2.7 (Apr 10, 2008)
============================

Fixes
=====
1. Problem: Cont00034704 - Linux iSCSI Xinan: Target occasionally
does not recover when running ifup/down
Cause: This is an expected behavior based on the very nature
of the test script and environment. Test script continously
toggles the interface up & down with a time difference of
1-sec. Also the interface is configured to aquire IP address
via' dhcp, which actually takes upto several seconds.
So iSCSI stack will hardly get a chance to reconnect to
target lun and after 120-secs SCSI disk will be taken offline
Change: Not applicable (not a bug)
Impact: 5709

2. Problem: Cont00034705 - Linux iSCSI: Errors seen when running ifup/down
with multiple targets attached
Cause: logic issue where a loop variable is not reset for each
session processing causing 2nd and subsequent sessions
to be retried for infinitely long time.
Change: fixed the logic
Impact: 5709

Enhancements
============

Version 1.2.6 (Apr 07, 2008)
============================

Fixes
=====
1. Problem: Cont00034260 - Linux iSCSI: Kernel panic while performing
ifup/down with target connected
Cause: Shutdown thread was waiting for 10-secs for iscsi driver to
cleanup all active session whereas ep_disconnect() thread
also has 10-sec timeout for TCP connection shutdown. This
was causing shutdown thread to return before connection
context destruction
Change: TCP connection termination timeout is set to a lower value
Impact: 5709

Enhancements
============
None

Version 1.2.5 (Apr 03, 2008)
============================

Fixes
=====
1. Problem: Cont00034315 - Linux iSCSI Xinan: Scanning disks during
max sessions test causes connection problems
Cause: CID range allocated by cnic driver was not in sync with
firmware expectation causing firmware to allocate CID
range for which memory is not allocated by the driver
Change: sync'ed driver range with the firmware range
Impact: fixes host memory corruption caused by this mis-match

2. Problem: Cont00034260 - Linux iSCSI: Kernel panic while performing
ifup/down with target connected
Cause: Timing issue caused cnic driver to free resources & stop
hardware while bnx2i is still registered. This resulted in
cnic driver crash when bnx2i calls cm_destroy() api call to
free 'cnic_sock'
Change: During repetitive shutdown process driver avoids async events
such as connection completion notifications, teardown and
connection destroy taks and relies on top level session freeze
to keep sanity
Impact: Fixes system crash

3. Problem: Cont00031780 - LinuxiSCSI:Unable to load bnx2id from
iscsiBoot on suse X86-64
Cause: RPM package was only install 32-bit version of 'bnx2id' and
relied of COMPAT feature in kernel module for interoperability.
However bnx2i source package did included a 64-bit version of
the binary and user was expected to install manually by hand
Change: RPM install script is modified to install 'bnx2id' binary based
on system architecture
Impact: Manual installed required to get iSCSI boot for 64-bit
architecture is no more required

4. Problem: Cont00033922 - Linux iSCSI Xinan: Kernel oops when doing
"service network restart"
Cause: duplicate of Cont00034260
Change: refer to Cont00034260 for more details
Impact: refer to Cont00034260 for more details

5. Problem: Cont00031404 - Linux iSCSI: A successful login occurs
eventhough initiator receives login response with T-bit
and C-bit set to 1
Cause: open-iscsi user daemon wasn't validating (C-bit && T-bit)
on received login response
Change: updated open-iscsi code to accomodate this in
6.2.0.742-0.6c (RHEL5.0), 6.2.0.865-0.8b (RHEL 5.1)
Impact: minimal

6. Problem: Cont00034385 - DF205266: DKMS RPM for bnx2i will not
install with bnx2 and bnx2x present
Cause: install script was running 'rpm -qa | grep "bnx2.*rpm"'
to determine multiple instances of bnx2 RPM is installed.
But 57710 dkms rpm is named "bnx2x-*" which also matches
the previous expression misleading script to believe multiple
instance of same driver.
Change: Modified the search pattern to avoid pitfall
Impact: DKMS

7. Problem: Cont00034316 - LinuxiSCSI: When installing bnx2i rpm package
on Linux-64, it does not install bnx2id64, iscsiboot needs
bnx2id64
Cause: RPM package was only install 32-bit version of 'bnx2id' and
relied of COMPAT feature in kernel module for interoperability.
However bnx2i source package did included a 64-bit version of
the binary and user was expected to install manually by hand
Change: RPM install script is modified to install 'bnx2id' binary based
on system architecture
Impact: Manual installed required to get iSCSI boot for 64-bit
architecture is no more required

Version 1.2.4 (Mar 17, 2008)
============================

Fixes
=====
Couple of issues related to PTE setup and queue size adjustments for
57710 are fixed. Also resolved issues with 'sysfs' entry being read during
driver load which used to crash the system because it was triggering
context stage buffer and PCI bar register access which are suppose to be
initialized during iscsi conn offload process. Driver now checks and returns
error if the context stage buffer or the pci bar mapping is not present

Fixes
=====
1. Problem: Cont00034202 - linuxiSCSI:bnx2i failed to compile on
SLES10SP1 X86-64
Cause: missing pci definition due to older kernel
Change: changed code to include 'resource_size_t' only if running
Linux kernel >= 2.6.18

Version 1.2.2 (Mar 10, 2008)
============================

Fixes
=====
None

Enhancements
============
Modified code to rearrange additional 'iscsi_kwqe_conn_offload3' to
include first RQ PTE followed by first CQ PTE [1 - 7]. As we don't intend
to include multiple CQ per connection in initial release, bnx2i will only
send '1' additional 'iscsi_kwqe_conn_offload3'

Version 1.2.1 (Feb 27, 2008)
============================

Fixes
=====
None

Enhancements
============
Added docbook style function & structure definition header and

============================

Fixes
=====
1. Problem: Cont00033893 - Linux iSCSI: bnx2id does not automatically
get loaded with v1.1.5
Cause: init scripts, bnx2id.redhat & bnx2id.suse included in v1.1.5
was in DOS file format, for that reason it was not executed
during system boot
Change: Converted init scripts to UNIX format
Impact: 5708/5709 iscsi testing

Enhancements
============
None

Version 1.1.7 (Feb 20, 2008)
============================

Fixes
=====
1. Problem: Cont00033898 - Linux iSCSI: kernel panic when connecting
to targets with bnx2i v1.1.5
Cause: Timing issue caused by new interface change b/w bnx2i/cnic/bnx2
Earlier 'pcidev' was available when NX2 device is presented to
bnx2i and recently CNIC was modified to expose 'pcidev' only
after bnx2i registers the device. But it could happen interrupt
is processed in register device context causing kernel panic
Change: bnx2i HBA adapter and pci_dev binding is determined in
bnx2i_start() instead of waiting for register_device() compl.
It is gauranteed bnx2i_start() is called before CNIC interrupts
are enabled on the device.
Impact: 5708/5709 iscsi testing

Fixes
=====
1. Problem: Cont00033899 - Linux iSCSI: RPM build errors on
SLES10 SP1 with bnx2i v1.1.5
Cause: missing PCI id macro for 5709 in pci_ids.h header file
Change: If not defined driver will define the macro to support
older kernel such as 2.6.16 carried by SUSE 10SP1
Impact: 5709 testing on SUSE10 SP1

1. Problem: Cont00031780 - LinuxiSCSI:Unable to load bnx2id from
iscsiBoot on suse X86-64
Cause: missing 32-bit compat libraries
Change: use 64-bit binary distributed in the package
Impact: Use 64-bit 'bnx2id' binary in iSCSI boot environment

2. Problem: Cont00032801 - bnx2i: Add 64 bit bnx2id to the release
Cause: NA
Change: source package includes 64-bit binary under
'bnx2i-1.x.y/bin/bnx2id64' (need to rename as 'bnx2id')
Impact: Enables user to build initrd image for 64-bit system

3. Problem: Cont00032141 - Linux iSCSI: Update README for MPIO
behavior in Section 5
Cause: default values got changed in the latest open-iscsi package
Change: Documentation changes
Impact: None

4. Problem: Cont00032671 - Linux iSCSI: Interface up/down stress
causes kernel softlockup with 5706S
Cause: race condition and also hba shutdown thread was
un-necessarily waiting on an event which is mutually exclusive
ending up in timeout every single time. This wait cluase
speeds hba shutdown process resulted because of 'ifdown'
command
Change: fixed spin_lock issues and removed unnecessary wait event
mentioned above

=============================
FIRMWARE - 3.7.19
========

Fixes
=====
1. Problem: Cont00031905 - Linux iSCSI: login/logout stress against
wintarget with multiple luns causes kernel panic
Cause: This was an issue caused by Win Targets wierd behavior of
holding on to SCSI INQUIRY response till TMF is sent. Other
issue was a race condition when logging off iSCSI session
while TMF request is pending. this would clear out all
commands while TCM timer was still active. When TMF timer
expires, it tries to operate on a command already freed
when session logged out.
Change: if TMF is active while trying to logout, driver will wait for
TMF request to either complete or timeout. Only them it will
send iSCSI logout pdu.
Impact: iSCSI TMF and iSCSI Logout rocessing

2. Problem: Cont00031884 - Linux iSCSI: Kernel panic with ifdown/up
when logged into target with 5708s
Cause: This issue was caused by a race condition depending on when
GOING_DOWN message is received by the driver. Once this message
is received, driver will start cleaning up all active sessions
and any session already in recovery mode won't be bothered.
But when this bug is hit, GOING_DOWN was received when session
was in login in phase (recovery mode) and driver let it continue
and return to user. Once bnx2i returns to cnic, cnic driver would
release all resources including cnic_sock structures. One of the
cnic_sock structure belonged to iscsi session which was going
through login phase. This connection will stay alive and will
be cleaned up during next iteration of interface bring down and
CNIC driver won't find refence to this cnic_sock as it was
already freed.
Change: When HBA is shuting down, driver will wait for recovering
sessions to complete iSCSI, then tear active sessions down
before returing to user
Impact: HBA shutdown code

========

NOTICE - iSCSI License enforcement is turned on.
======

Fixes
=====
1. Problem: Cont00031668 - Linux iSCSI Offload Licensing not enforced
Cause: Dupicate of CQ31577, FW identifies the card as HP NIC instead
of HP LOM, FW was checking for entire register instead of a
specific bit
Change: change the checking to refer to only a specific bit in MCP's
scratchpad and not the entire register
Impact: Licensing should work as expected on oem systems

2. Problem: Cont00031671 - Linux iSCSI: unable to connect to maximum number
of sessions (64), on an x86_64 system
Cause: Driver was allocating only 40 endpoint structures on
64-bit systems. Driver has a logic of allocating a maximum of
#n pages of memory for each control structures (endpoint,
connection, session, etc') and #n is set to 4. On a 32-bit
system size of endpoint structure is 256B whereas on a 64bit
system it is ~400B. So driver was able to allocate 40 endpoint
structures
Change: increaded number of pages per control structure to '8'
Impact: None

3. Problem: Cont00031655 - Linux iSCSI: bnx2i: Error message - cmd not
allocated w/ v1.0.29
Cause: one command structure was getting leaked when session goes into
recovery due to nop-out timeout
Change: NOPOUT requests are also queued in active command queue and
freed when session is cleaned up
Impact: None

4. Problem: Cont00031662 - Linux iSCSI: Kernel Oops running disktest with
maximum sessions test
Cause: driver was hard coding "sht->can_queue' parameter to 128
(max outstanding commands issued by SCS-ML). Where as the
QP size was decreased using 'sysfs'. It get more complicated as
'can_queue' parameter is advertised when iscsi transport is
registered which happens even before 'sysfs' setup. So will have
to remove 'sysfs' support for changing SQ/RQ/CQ size and instead
provide module parameters to choose these parameters based on
requirements for number of the iSCSI connection
Change: Removed 'sysfs' support for changing SQ/RQ/CQ size and instead
module parameters are included to change these parameters.
Also 4 command structures are reserved for slow path (TMF ABORT,
NOP-OUT, etc) commands.
Impact: None

Impact: None

2. Problem: Cont00031509 - LinuxiSCSI:iSCSIBoot failed to to successfully

subsequent NETEVENT_NEIGH_UPDATE for proper neighbour status.
Impact: None

3. Problem: Cont00031517 - LinuxiSCSIBoot: Connection is not restored
when disconnecting Primary HSRP router
Cause: 2.6.16 kernel does not support NETEVENT_NEIGH_UPDATE
Change: 2.6.16 kernel does not support NETEVENT_NEIGH_UPDATE, so router
failover with gratuitous ARP will be unknown to the driver.
To fix this issue, a timer was added to check the ARP entries

1. Problem: Cont00031421 - Linux iSCSI: Hotplug feature - Does not reconnect
to target if nic is removed and put back in if there is already
an iSCSI session established
Cause: Offload driver cannot support this and driver will cleanup all
activer iSCSI session/connections which also includes all
outstanding commands and even releases the adapter structure
as part of hot remove. When the adapter is added there won't
be enough state information to restore the session. It is
is a good idea to orderly shutdown all iSCSI sessions before
removing the device
Change: Will not be addressed
Impact: None

2. Problem: Cont00031193 - LinuxiSCSI:iSCSIBoot continously drops and then
recover iscsi connection
Cause: This issue happens when 'iscsid' daemon is killed and restarted
while one or more iSCSI session are active. When the daemon is
restarted, it does not have reference to old TCP connection but
it knows iSCSI session and connection information. So iscsid
blindly stops the iSCSI connection, establishes a new
TCP connection and tries to bind it to iSCSI connection. This
results in a resource conflict situation as there is already
a TCP conn bound to iSCSI connection causing a bad state with
broken link between EP and CONN structures
Change: When driver detects this condition old TCP connection is
shutdown and cleaned up before binding the new TCP connection
to iSCSI connection
Impact: None

3. Problem: Cont00031205 - iscsid does not get the established session info

FIRMWARE - 3.7.12 + COM (Event Coalescing)
========

NOTICE - iSCSI License enforcement is turned on.
======

Fixes
=====
1. Problem: Cont00031304 - Linux iSCSI: Does not see all the disks
after LUN has been remove and then re-added on the target
Cause: bug in SCSI sense data handling code - driver was copying
entire RQ buffer as is, actually first 2 bytes (length field)
should be omitted when copying to SCSI command sense buffer
Change: Only actual sense data is copied to sense buffer
Impact: None

2. Problem: Cont00031238 - Linux iSCSI: Kernel panic after running
disktest (w/various io) to Cisco target overnight
Cause: this is caused by race condition when command is completed
while TMF request is pending. 'cmd->scsi_cmd' will be set to
NULL ptr after completing the command to SCSI-ML and system
paniced dereferencing cmd->scsi_cmd when TMF completes waking
up the waiting thread.
Change: driver checks if the cmd completed while waiting for iSCSI TMF
Impact: none

3. Problem: Cont00031131 - LinuxiSCSI:Using HP target iscsi session drops
after nop-out timedout after 15 seconds on RH5
Cause: some targets do not explicitly respond to NOPOUTs when there are
active commands. These iSCSI targets expect initiator to update
sequence numbers from SCSI CMD RESPONSE pdus
Change: bnx2i driver will not send nopout on wire when following
conditions are met -
1. there are active SCSI commands
2. one or more SCSI commands where sent between this and
previous nopout request

Instead driver will itself respond to nopout. Infact we can even
change iscsid to keep track of 'cmdsn' and send down nopout
request only if connect is truely idle. We will evaluate changes
to iscsid and work to community to incorporate the change.
Impact: Initiator's proactive NOPOUTs are not seen on wire when the
iSCSI connection is not truely idle

4. Problem: Cont00031121 - Linux iSCSI: Kernel panic when running
ifdown/up test + disktest
Cause: In interface going down notification, iSCSI connection context
was destroyed without tearing down the TCP connection.
Another issue was option-2 s/w was not handling
'SYN - ACK - RST' condition properly.
Change: Code is fixed to attempt TCP connection shutdown (FIN/RST)
before destroying connection context.
Impact: none

5. Problem: Cont00031024 - Linux iSCSI: Keyboard locks up when running
traffic to Sanrad w/ Suse10 SP1
Cause: There were a bunch of issue uncovered by this test -
1. race condition in cleanup code
2. error while assigning LUN value during TMF request wqe
3. issue related to RQ producer index posting, from the second
wraparound, indices posted was in the range 0x0 - 0x10,
0x8000 - 0x8010. Correct RQ producer index range is
0x1 - 0x10, 0x8001 - 0x8010 (this example considers total
of 16 RQ buffers)
4. RQ producer suppose to be increment by driver on every
unsolicited PDU that generated a CQE(even without iSCSI data)
Change: code changes to take care of all above said issues
Impact: none

6. Problem: Cont00031221 - Linux iSCSI: Bonnie++ reports drastic I/O error
when running to EMC AX100SCi target
Cause: combination of Cont00031304 and Cont00031024 (issue #4)
Change: combination of Cont00031304 and Cont00031024 (issue #4)
Impact: none

7. Problem: Cont00031203 - Linux iSCSI: LUN rescan does not complete after
cable pull when connected to multiple targets
Cause: couple of issues attributed to this issue -
1. order of conditional checks - link down check was before
session recovery state. Actually order should be reversed
2. old recovery state should be a per session attribute but
instead was kept as static variable in bnx2i_queuecommand().
When there were multiple sessions this broke state transition
Change: Fixed both the issues
Impact: None

8. Problem: Cont00031194 - Linux iSCSI: traffic does not resume on standby
nic when cable pulled during MPIO testing
Cause: couple of issues attributed to this issue -
1. order of conditional checks - link down check was before
session recovery state. Actually order should be reversed
2. old recovery state should be a per session attribute but
instead was kept as static variable in bnx2i_queuecommand().
When there were multiple sessions this broke state transition
Change: Fixed both the issues
Impact: none

9. Problem: Cont00031383 - LinuxiSCSI:iSCSIBoot encounters connection
failure during iscsiBoot
Cause: Related to option-2 issue of not handling 'SYN - ACK - RST'
condition properly.
Change: Instead of sending Reset on bad ack sequence segment when
expecting syn/ack, just redirect to L2 in order for it to
send the reset (for the sake of simplicity)
Impact: Second SYN request should succeed in establish the
3-way handshake

Enhancements
============
Event coalescing is implemented

Version 1.0.18 (Aug 30, 2007)
=============================
FIRMWARE - 3.7.11
========

NOTICE - iSCSI License enforcement is turned on.
======

Fixes
=====
1. Problem: Cont00031121 - Linux iSCSI: Kernel panic when running
ifdown/up test + disktest
Cause: Driver was not tearing down the connection when interface was
brought down. This was causing TCP connection to be active on
the target side and won't let initiator to reuse the port.
Driver is fixed to attemp TCP connection teardown but firmware
needs to fixed as well to either indicate error status to
driver or return sending SYN packet when first 3-way handshake
fails
Change: Driver initiates TCP connection teardown process before
cleaning up iSCSI state
Note: Need firmware fix to resolve SYN - ACK - RST issue as same
issue will resurface when 'ifdown' command is issued when cable
is disconnected
Impact: none

Enhancements
============
None

Version 1.0.17 (Aug 29, 2007)
=============================
FIRMWARE - 3.7.11
========

NOTICE - iSCSI License enforcement is turned on.
======

Fixes
=====
1. Problem: Cont00031063 - Linux iSCSI: Kernal panic when attempting
target login (w/o authentication) with certain login parameters
Cause: this is an iET target implementation issue. Target is not
setting 'F' bit in the last datain pdu of a sequence.
In this test scenario, MBL = MRDSL (initiator) = 2K and the
command was a scsi read \ with exp data length = 4K.
Target sends 2 datain's -
1. datasn=0, data segment len = 2K, F=0, S=0
2. datasn=1, data segment len = 2K, F=1, S=1

In first DATAIN pdu, 'F' should have been set to '1'.
MIPS firmware correclty detects the error & notifies the driver.
Driver actually starts the recovery phase, but every single
connection will end up in same fate as the 1st. As this happens
in SCSI discovery phase right after the iSCSI login, user shell
will never return and iscsid will keep retrying.
Change: Fixed driver crash issue and made code changes to iET software to
be more 3720 compliant. SWE will publish the code changes to
iET development community
Impact: none

Enhancements
============
Made some performance improvements change in CNIC driver which should
avoid some spurious interrupts under heavy I/O

Version 1.0.16 (Aug 23, 2007)
=============================
FIRMWARE - 3.7.11
========

NOTICE - iSCSI License enforcement is turned on.
======

Fixes
=====
1. Problem: Cont00030122 - Linux iSCSI: Disk does not reappear after
cable pull on Sanrad target
Cause: link change events was not handled in iscsi driver
Change: Link change events are handled in driver correctly and
bnx2i driver will not issue new scsi commands / scsi tmf
requests to chip if the link is down
Impact: none

2. Problem: Cont00031024 - Linux iSCSI: Keyboard locks up when running
traffic to Sanrad w/ Suse10 SP1
Cause: This issue uncovered few bugs -
1. race condition in cleanup code
2. there was a coding error while assigning LUN value
during TMF request wqe formation
3. logic error in RQ producer index posting - from second
RQ index wrap around, producer index posted was
(0x0 - RQ_Size) and (0x8000 - (0x8000 + RQ_Size)).
Correct indices range is (0x1 - RQ_Size) and
(0x8001 - (0x8001 + RQ_Size))
Change: All above said issues were resolved
Impact: none

Version 1.0.15 (Aug 22, 2007)
=============================
FIRMWARE - 3.7.11
========

NOTICE - iSCSI License enforcement is turned off.
======

Fixes
=====

1. Problem: Cont00030809 - Linux iSCSI: Able to log in to target when
FirstBurstLength > MaxBurstLength
Note : Check more accurate description of issue at hand when this
issue was first resolved
Cause: To be in sync with SW open-iscsi implementation, offload driver
will not allow FBL > MBL when either immediate data or
unsolicited data is enabled, irrespective of target advertised
MRDSL
Change: Not to allow FBL > MBL when either immediate data or
unsolicited data is enabled
Impact: None

Version 1.0.14 (Aug 21, 2007)
=============================
FIRMWARE - 3.7.11
========

NOTICE -
======
iSCSI License enforcement is turned off. Also TCP port binder
utility is bundled in this release, user has to start
'portbind' daemon before attempting to establish iSCSI sessions

Fixes
=====
1. Problem: Cont00030892 - Linux iSCSI: Enhancement Request - Print out
appropriate message when session cannot be established due to
restriction in iSCSI licenses
Cause: MIPS firmware was returning single failure error code
Change: MIPS firmware returns newly defined error code if unable to
allocate iSCSI context space
Impact: None

2. Problem: Cont00030042 - Linux ISCSI - Session freezes running
ISCSI initiator at 10Mb/s-Hd
Cause: iscsi_discovery script under open-iscsi/utils folder was used to
discover and connect to targets. This scripts was using iSER to
connect to target, so in effect 2 simulaneous connections were
made to target
Change: not to use iscsi_discovery
Impact: None

3. Problem: Cont00031024 - Linux iSCSI: Keyboard locks up when running
traffic to Sanrad w/ Suse10 SP1
Cause: race condition in cleanup code and also there was a coding error
while assigning LUN value during TMF request wqe formation
Change: cleaned up error path to hammer out few remaining bugs
Impact: More stable error recovery code

4. Problem: Cont00031040 - Linux iSCSI: Kernel oops occurs between long
transmit timout and recovery.
Cause: Same as Cont00031024
Change: Same as Cont00031024
Impact: Same as Cont00031024

5. Problem: Cont00029844 - Linux ISCSI - Bonnie++ fails while testing
against Linux Target
Cause: Same as Cont00031024
Change: Same as Cont00031024
Impact: Same as Cont00031024

6. Problem: Cont00030809 - Linux iSCSI: Able to log in to target when
FirstBurstLength > MaxBurstLength
Cause: This is a iSCSI target implementation issue - during login
reponse following parameters were agreed b/w target and
the initiator -
1. MaxBurstLength (MBL) - 32768
2. FirstBurstLength (FBL) - 65536
3. MaxReceiveDataSegmentLength Initiator - 131072 (advertised)
4. MaxReceiveDataSegmentLength Target - 8192 (not advertised,
spec defaults)
5. ImmediateData=Yes
6. InitialR2T=Yes

When all these parameters are put together Initiator can only
send 8192B of immediate data and no unsolicited data. So any
negotiated FBL value greater than 8192 is a waste and target
might be ignoring it.
Change: Third party issue
Impact: Won't be addressed

Enhancements
============
Fixed one issue related to iSCSI R2T statistic counter update code.
Also 'portbind' utility is bundled with this release and the user has
to start the daemon before attempting to establish iSCSI sessions

=============================
FIRMWARE - 3.7.10_b0
========

NOTICE - iSCSI License is required to use iSCSI Offload
======

Fixes
=====
1. Problem: Cont00030950 - Linux iSCSI: FIN packet is NOT sent out
from initiator after each target logout.
Cause: Driver was using a single flag to mark FIN received and
RST received. Driver used to skip cm_close() path when this
flag is set and directly initiate connection context destroy
Change: Now this flag is separated into 2 different flag bits
and driver will take following action based on state machine -
1. FIN received - initiated an option-2 request to send FIN
if remote socket layer sent us FIN either with logout
respons PDU or standalone TCP segment with FIN flags set
2. RST received - will skip cm_close() path and directly
proceeds to destroy connection context
Impact: should also resolve occational "4 - encountered connection
failure" error condition when attempting to create a
new iSCSI connection

2. Problem: Cont00030948 - Linux iSCSI: Kernel Oops occurs after
3-way handshake (for target login) failed.
Cause: In ep_disconnection thread driver tried to dereference
a null pointer, ep->sess. this structure element is assigned
correct value in conn_bind() routine and this routine is not
called when ep_connect() fails because of 3-way handshake
failure
Change: Check validity of ep->sess pointer before de-referencing
Impact: None

3. Problem: Cont00030903 - Linux iSCSI: Cannot log in to target after
unloading/loading iSCSI offload drivers if iscsid is not
restarted
Cause: Everytime is driver is unloaded and reloaded, it is not
guarenteed the same 64-bit handle is allocated to
iSCSI transport name. 'iscsid', open-iscsi user daemon
will cache transport attributes/properties only when the
transport name is first discovered. This will result in
'iscsid' trying to use the stale transport handle which
is not recoqnized by kernel iscsi tranport module
Change: 'iscsid' is changed to check for changed transport handles
of existing transport names while scanning iscsi transports
directory for updates
Impact: Need to co-ordinate with Mike Christie to push this change
upstream

4. Problem: Cont00029670 - Linux ISCSI - encounter error
(4 - encountered connection failure) when loging to the target
Cause: related to Cont00030948, as initiator did not send FIN - ACK,
socket was alive at the other end. This causes target to
ignore SYN packet when tuple matches with exisiting active
connection and send an ACK segment instead
Change: Driver code is modified to gracefully shutdown the connection
with a FIN/ACK TCP segment before destroying the
iSCSI connection context. This ensure ordely shutdown of
TCP socket at the other end.
Impact: None

5. Problem: Cont00030227 - Linux iSCSI: Login/logout and traffic stress
test causes kernel panic
Cause: KCQ context was not properly re-initialize when driver
tries to stop KCQ and re-init KWQ/KCQ
Change: driver and mips firmware was fixed to correctly re-initialize
KCQ context when KWQ/KCQ is re-initilaized by the driver
Impact: None

6. Problem: Cont00030817 - Linux iSCSI: Login/logout stress causes
iscsid process to disappear
Cause: related to Cont00030227
Change: refer to Cont00030227 entry above
Impact: None

========

Fixes
=====
1. Problem: Cont00029443 - Linux iSCSI: iSCSI licenses in xDiag not
enforced
Cause: not implemented as licensing scheme was finalized very recently
Change: Licensing code is implemented in MIPS firmware
Impact: iSCSI Offload won't work on engineering boards / servers LOMs
which does not carry proper licensing

2. Problem: Cont00030863 - Linux iSCSI: Transport name for 5706 devices is
titled bcm5708-xxxxxx w/ v1.0.07 and above
Cause: PCI device ID field was cleared by mistake which cased driver to
choose the default device type, '5708'
Change: fixed in code
Impact: transport name format for 5706 devices will be 'bcm5706-xxxxxx'

========

Fixes
=====
1. Problem: Cont00030302 - Linux iSCSI: Session disconnect and
kernel panic when formatting EMC target w/
NOP Out interval set to 10
Cause: there were a few repeated iSCSI protocol warning messages
Change: Driver changed to display each warning once for each session
Impact: none

2. Problem: Cont00029546 - Linux iSCSI: Requires upgrade to 2.6.19
kernel on Suse10
Cause: SLES10 update 1 had older open-iSCSI components
Change: SLES10 SP1 has a newer open-iSCSI and we don't need kernel upgrade
Impact: none

3. Problem: Cont00030820 - Linux iSCSI: Error messages seen on
Cisco MDS 9216 target w/ v1.0.07
Cause: FW generates iSCSI Error KCQE for each iSCSI protocol
violation whether is configured to be treated as warning
or error. So driver will priting message for each indication,
this caused a flury of messages and slowing down the system.
Now driver is changed to print each type of warning only once.
Change: Driver prints message only once for each iSCSI protocol
violation which is configured to be treated as WARNING
and not an ERROR
Impact: none

4. Problem: Cont00029689 - Linux iSCSI: Maximum of 16 iSCSI sessions
supported
Cause: Driver was limiting max offloaded connections to 32
Change: driver and FW are equipped to support upto 64 iSCSI connections
Impact: none

5. Problem: Cont00030805 - Linux iSCSI: iSCSI Rx Statistics not
incrementing w/ v1.0.07
Cause: issue was introduced in v1.0.07 when code was revamped to
meet Linux coding standards. A stale structure element
was being check to determine whether the completion is for
READ or WRITE command. 'Cuz of constant value of this
absolete structure member, same code path was take all
the time.
Change: Correct structure member is referenced to determine whether
the command is SCSI READ or WRITE
IMP: currently couple of counter are not correctly implemented
in FW and should be taken care in next release. Other than
these (R2T/DATAOUT pdu count) everything else look to be fine.
Impact: none

Enhancements
============
This release is tested on SUSE Enterprise Linux Server 10 (Service
Pack 1). Open-iSCSI packaged with SLES 10 SP1 works with offload iSCSI driver
and we do not require kernel update on SLES

Version 1.0.7 (July 25, 2007)
=============================
FIRMWARE - 3.7.7
========

Fixes
=====
1. Problem: Cont00030060 - Linux iSCSI: Hotplug using fakephp driver
w/ iSCSI drivers loaded does not work
Cause: Hotplug feature was incomplete
Change: This is implemented correctly in cnic as well bnx2i driver
in version 1.0.7 release
Impact: Hotplug feature is fully supported

2. Problem: Cont00030302 - Linux iSCSI: Session disconnect and kernel panic
when formatting EMC target w/ NOP Out interval set to 10
Cause: couple of issue attirbuted to this -
1. race condition in driver caused by not properly guarding
critical sections
2. EMC target has issues handling nop-out requests when
link is not idle, i.e. if a SCSI command follows the nop-out,
it will not respond with nop-in. This caused system crash as
the driver was not properly recovering from this failure.
Change: System crash is fixed and the initiator reconnects to target
after tearing down the connection
Impact: None

3. Problem: Cont00030013 - Linux iSCSI: Running disktest read/write with
NOP Out interval set to 10 causes system lockup
Cause: there was a bug in 'cmdsn' assignment code
Change: fixed 'cmdsn" assignement code
Impact: None

4. Problem: Cont00030066 - ISCSI Linux - System hangs when issue a couple
of ifdown/ifup command
Cause: There were few bugs in iscsi driver not properly synchronizing events
such as connection setup and interface reset happening simultaneosuly.
During ifdown, the cnic will shutdown and a number of bugs were triggered.
The L4 connection code did not unregister, and so during subsequent ifup,
it could not be registered again. There was also a lock imbalance when
L4 connection code tried to register again, and this caused the soft lockup.
Change: Now it's all taken care and also driver tracks age of the adapter
(number of times it's reset) which allows iscsi driver to detect if
the network interface is reset between 2 events from iscsi daemon,
e.g. connect establishment and login pdu send
Impact: None

4. Problem: Cont00029719 - Linux iSCSI: Enhancement Request - MTU size > 1500
should not be allowed for bnx2 driver
Cause: bnx2i driver was not checking MTU
Change: bnx2i driver will disallow any iSCSI connection offload if network device's
MTU is > 1500B
Impact:

Enhancements
============
Source code was revamped to meet Linux coding standards

FIRMWARE - 3.7.6_A0
========

Fixes
=====
1. Problem: Cont00030435 - Linux iSCSI: Cannot log into certain targets
w/ driver package v1.0.05
Cause: Linux iSCSI package version 1.0.5 contained firmware version 3.7.4
and it seems the firmware has this issue. This issue not
seen with firmware 3.7.6_a0
Change: new firmware image
Impact: none

Enhancements
============
None

Version 1.0.5 (July 06, 2007)
=============================
Fixes
=====
1. Problem: Cont00030060 - Linux iSCSI: Hotplug using fakephp driver w/
iSCSI drivers loaded does not work
Cause: Hotplug was not implemented properly
Change: Support was added in bnx2i driver and also bnx2i-cnic driver
interface was upgraded to support hotplug
Impact: all of login - logout, driver load - unload test cases need
to be re-run to thoroughly validate the interface change

Enhancements
============
1. This release includes iSCSI context dump utility and the required
driver hooks is included in this release
2. bnx2i and cnic driver interface changed quite a bit while adding
hotplug support

Version 1.0.04 (May 30, 2007)
=============================
Fixes
=====
None

Enhancements
============
Added print statement to display network interface and iSCSI transport
names for each NX2 device enumerated by the driver. Other enhancements
include cosmetic changes to README_iSCSI.txt file and the bnx2 driver
includes latest mips firmware.

Version 1.0.03 (May 29, 2007)
=============================
Fixes
=====
1. Problem: Cont00029452 - Linux iSCSI: Error messages seen during
login/logout on Equallogic target with v1.0.01
Cause: iSCSI driver was attempting to do session recovery every time
it received a TCP FIN or RST from the remote peer. Actually
session recovery has to attempted only if the sess is in FFP state.
Change: checks are put in place to avoid any un-necessary recovery attempts
Impact: none

2. Problem: Cont00029655 - Linux ISCSI - Seeing error in the /var/log/messages
when connecting to Linux target
Cause: duplicate of Cont00029452
Change: see notes for Cont00029452
Impact: none

3. Problem: Cont00029662 - Linux iSCSI: Problem formatting EMC target
Cause: protocol violation (invalid LUN field in R2T PDU) by the target
Change: removed couple of strict protocol checking in MIPS firmware
Impact: might affect iSCSI protocol validation certifications, will
reinstate the checks once we have this fixed in the target end.

4. Problem: Cont00029690 - Linux iSCSI: Login attempt to 17th session causes
the 16th session to be dropped
Cause: 'cid_free_cnt' was not decremented after allocating a 'iscsi_cid'
from the free list. This caused false queue full condition even
when all the entries are allocated.
Change: 'cid_free_cnt' is properly updated while allocating iscsi_cid from
the free pool
Impact: driver will gracefully turn down request to open 17th connection

5. Problem: Cont00029535 - Linux iSCSI: iSCSI session drops and fails to recover
Cause: There was a diconnect between BD table allocation and what is advertised
to the SCSI layer. Driver was allocating BD table with max 32 entries
for each command and what was registered with SCSI-ML was a bigger value.
Change: Driver now allocates BD table of size equal to 'sg_tablesize' value
specified in scsi_host_template structure
Impact: None

6. Problem: Cont00029432 - Linux iSCSI: Does not automatically reconnect to
target after cable pull test
Cause: 'fdisk -l' will result in couple of read commands and these gets
queued up in the TX pipeline (retransmission queue) and firmware will
not complete CMD_CLEANUP requests for commands that have some entries
in the retransmission queue. Unless the number of CMD_CLEANUP requests
issued and responses that got completed match, driver will assume
connection can't be shutdown properly.
Change: Driver will teardown connection without cleaning up the commands
when needed and it is the right thing to do.
Impact: None

Bug fixes in other modules :
--------------------------
a) Cont00029590 - Linux iSCSI: Unable to connect to iSCSI target on a
tagged vlan using offload iSCSI
Fixed in cnic driver - vlan was not supported by the option-2
component of cnic driver. Code was added to support vlan tagging
and checking if the route to desitination is over a vlan interface.
cnic driver will set correct VLAN id while sending down option-2
connect request.
b) Cont00029579 - Linux iSCSI: Running ethtool -t with target connected
causes kernel panic
Fixed in bnx2 driver - Asynchronous reset during self-test causes
the cnic driver to crash. The fix is to disallow offline selftest
when cnic driver is loaded.

Version 1.0.02 (May 22, 2007)
=============================
Fixes
=====
1. Problem: Cont00029425 - Linux iSCSI: Issue when connecting to 16+ LUNs
Cause: RQ buffers replenish code was commented out. By default iSCSI QP
is created with 16 RQ buffers, so were we allowed to discover
16 SCSI LUNs. For the 17th LUN firmware did not have RQ buffer
to place sense data.
Change: cleaned up RQ buffer replenish code
Impact: can connect to > 16 LUNs and run I/Os

2. Problem: Cont00029532 - Linux iSCSI: Running more than 64 outstanding I/Os
on multiple LUNs w/ disktest has issues
Cause: iSCSI initiator was not properly honoring the iSCSI Session Command
window presented by the target. Netapp is actually only providing
command window of 64 and once violated would drop the connection
via' REJECT and ASYNC messages.
Change: iSCSI driver is taking care of iSCSI command window correctly

3. Issues fixed in other modules -
a) Cont00029404 - Linux iSCSI: Unable to login to Cisco MDS 9216
Fixed in chip software (MIPS firmware) - Wrong KCQE opcode was
due an error in error reporting mechanism. New FW version 3.7.1.A0
fixes this.

b) Cont00029415 - Linux iSCSI: HP target rejects NOP Out from our driver
Fixed in chip software (MIPS firmware) - The correct opcode is
sent to the wire now. Fixed in ver 3.7.1.A1

c) Cont00029542 - Linux iSCSI: Problem formatting Stringbean target
with ext3 file system
Fixed in chip software (MIPS firmware) - The problem was present
due to wrong error reporting mechanism in FW. This mechanism is
fixed in new FW version 3.7.1.A0

d) Cont00029571 - Linux iSCSI: Adding new session causes previous session
to be dropped on Equallogic
Fixed in chip software (MIPS firmware) - Wrong cam index handling
caused the wrong connection to be flushed away from cam while
removing other coonnection

e) Cont00029579 - Linux iSCSI: Running ethtool -t with target connected
causes kernel panic
Fixed in bnx2 driver - Asynchronous reset during self-test causes
the cnic driver to crash. The fix is to disallow offline selftest
when cnic driver is loaded.

f) Cont00029634 - Linux iSCSI: Changing MTU size w/ drivers loaded causes
kernel panic
Fixed in bnx2 driver - For now, the bnx2 driver will not permit
MTU changes after CNIC is loaded. To change the MTU, you need
to do so before loading the cnic driver. A better method will
be available in future versions.

g) Cont00029366 - Linux iSCSI: Unable to connect to EMC AX100SCi
Fixed in chip software (MIPS firmware) - The bug is due to
target TCP protocol vioaltion (not our bug actually).
Now once we support window scale option - this issue is resolved.

Enhancements
============
Implemented bnx2i driver maintained iSCSI statistics (Cont00029583).
Some of the statistics counters are to be implemented by MIPS firmware
and the interface specification. Once those are in place Cont00029583
will be resolved. Also default value of HC_COMP_PROD_TRIP is changed
from 0x00020004 to 0x00020008 to boost 2 port performance

Version 1.0.01 (May 08, 2007)
=============================
Fixes
=====
1. Problem: Cont00029362 - Linux iSCSI: Proactive NOP Out not handled
by the driver
Cause: 'CmdSN' was not specified in nopout SQ WQE and was always
accompanied with cmdsn value of 0x0000000. Also NOPIN received
in response to Initiator's proactive NOPOUT was not propogated
to open-iscsi user daemon.
Change: correct 'cmdsn' is used while posting NOPOUT request to ship and
also code was added to send nopout pdu header to user daemon
Impact: NA

2. Problem: Cont00029416 - Linux iSCSI: Login/logout stress causes kernel panic
Cause: System crashed because of an issue in KCQ processing code in
the CNIC driver
Change: Refer to CNIC driver's release notes for further information

Enhancements
============
None.

Version 1.0.00 (April 27, 2007)
===============================

Initial release to QA team.

This release will support most iSCSI full feature operations including
1. SCSI CMD, TMF, NOPIN, NOPOUT, ASYNC and LOGOUT
2. REJECT is currently not supported
3. All IO size from 512B to 512KB

Driver unload and reload is also supported. This driver will work on Linux
Kernel 2.6.18 and 2.6.19 and open-iscsi software 2.0-724 or later is required
to make connections to iSCSI targets. iSCSI target discovery using 'SendTargets'
is the only one tested so far, but it should matter to bnx2i as complete
discovery is handled by the open-iscsi user code.

Following targets were used during initial debugging stages and should be
fully supported -
1. Equallogic PeerStorage PS100E
2. Netapp Target - FAS250, FAS270
3. Linux Software Target - iET
4. Microsoft's StringBean target, minimal validation by developers
