Problems Fixed: - FRU VPD fields are now properly populated on CN4054 and CN4054R - Fixed UE resulting slow boot at UEFI splash screen and NIC devices removed - When using VMQ with Windows Server 2012 or 2012R2, the user may experience VM connectivity loss, packet drops, system hangs, inability to shutdown VMs and possible system crashes on shutdown. The complete solution also requires 10.2 based Windows NIC driver. - Resolved an issue for auto negotiation between the x240 onboard LoM to the EN2092 1Gb switch
Incremental Interoperability: - Inventory support for the Flex xHMC (Chassis Hardware Management Console)
Known Issues: - Server hangs at "Scan for Fibre Devices", when port disable/enable performed on the Brocade Converged 10 Gb Ethernet Switch Module for IBM BladeCenter. Do not force the link down after POST has completed and then attempt a discovery of the SAN. If you do a reboot is needed.(159125)
- To disable BFS after BOFM or IFM have been enabled, it must be done by setting BFS manually in the EFIBoot config utility or sending a BOFM default command to the port. This is working as expected and we are documenting it here.(159505)
- Intermittently, 255 vPorts can not be created successfully in Windows with the error "ERROR: <127>: Not enough HBA or fabric resources. VPort not created!". There is no known workaround other than to reduce the number of configured vPorts.(155807)
- Target login will fail if you dynamically reconfigure the SAN after POST has executed. If you do, then reboot the system.(159121)
- PXESelect showing incorrect MAC address, bandwidth & SVID values. This bug is a cosmetic issue and only impacts PXESelect. The values which are not displayed correctly in PXESelect can be viewed in UEFI, OCM, and on the switch.(151140)
- IFM Boot target is consumed on a particular port even though the target is not accessible to that port. IFM/BOFM boot target configuration is not supported. This limitation has existed for several code releases and we are now documenting it here.(159226)
- "Configurations have changed" message seen in UEFI setup screen when no changes were made. This pop-up can be ignored and will be fixed in a future code release.(159086)
- The server may hang at "Connecting Boot Devices and Adapters" if both FCoE ports have boot targets configured when using a 10Gb Ethernet Pass-Thru Module for IBM BladeCenter. The server will not hang if only a single port is configured with a boot target.(157137)
- FCoE VLAN ID is being displayed incorrectly as hexadecimal in UEFI menu. This is a cosmetic issue only. The correct VLAN is properly assigned, so there is no functional impact. The actual VLAN ID can be observed elsewhere. (159561)
- In FCoE configurations with BE3 in UFP mode on System x3690 X5 servers, a UEFI rescan is required to boot to the OS. This renders UFP not supportable in UFP/FCoE configurations(158669)
- After making changes to any options in the sub-menus under 'controller configuration' in the Emulex UEFI NIC configuration utility and escaping to the prior menu, there is no prompt to save the changes. Be sure to select 'Save' before exiting the configuration menu. Applies to some legacy rack and blade servers.
- Intermittently, when changing the multichannel mode, the system will not auto-reboot after exiting F1 UEFI setup and will continue through POST. Manually reboot the server to ensure all changes are applied. Applies to some legacy rack and blade servers.
- When using a Cisco Nexus 4001i Switch Module, intermittently the 10Gb link may come up as 1Gb link speed. An internal switch port bounce will typically establish a 10Gb link. Setting the switch port speed to fixed 10000 will also allow a guaranteed 10Gb connection. More info available in the Cisco Nexus 4001i Switch Module firmware release notes.

Copyright (c) 2004 - 2014 Broadcom Corporation All rights reserved
package 2.710.13 (Sep 03, 2014) =============================== Fixes ----- 1. Problem: Package processing issues with some kernels
Cause: kernel compatibility issue.
Change: Improved packet processing
Impact: Linux.
package 2.710.10 (Feb 25, 2013) =============================== Fixes ----- 1. Problem: Package does not compile on newer kernels
Cause: kernel compatibility issue.
Change: Added new CFLAGS from bnx2x Makefile for bnx2x_compat.h.
Impact: Newer distributions such as RHEL7.
bnx2 2.2.5f (Feb 20, 2014) =========================== Fixes ----- 1. Problem: (CQ72407) "shutdown -h now" causes NMI on 5709 in some scenarios.
Cause: If the function has not been brought up (ifup), system shutdown will cause a WAIT3 and D3 sequence without prior chip reset. This may cause the firmware to power down the PHY which will cause the function to become unresponsive to MMIO reads. The CPU will timeout and NMI as a result.
Change: Added some logic to tell firmware to skip the PHY power down.
Impact: 5709 only. Only ifdown and system shutdown sequences are affected. No run-time impact.
bnx2 2.2.5e (Feb 05, 2014) =========================== Enhancements ------------ 1. Change: Indication if the driver is beta or release in a printk upon firmware dump.
Impact: ESX only.
cnic 2.5.18d (Feb 05, 2014) ============================ Fixes ----- 1. Problem: (CQ72694) Crash in bnx2x_cnic_notify() when getting iSCSI statistics.
Cause: Calling bnx2i_get_stats() after bnx2i has unregistered the device.
Change: cnic should use the per device RCU protected cp->ulp_ops[] when making the upcall to get statistics. It was incorrectly using the global cnic_ulp_tbl which is always valid even if individual devices have been unregistered.
Impact: iSCSI and FCoE
bnx2 2.2.5d (Jan 14, 2014) =========================== Fixes ----- 1. Problem: (CQ71941) Kernel panic when loading bnx2 driver on RHEL6.5 with inbox cnic driver loaded.
Cause: Incompatibility with inbox cnic driver.
Change: Added padding in bnx2 structure so that the inbox cnic driver will always detect NULL in the cnic_probe field.
Impact: RHEL6.5 and newer kernels (SLES11SP3 is not affected)
bnx2 2.2.5c (Jan 06, 2014) =========================== Enhancements ------------ 1. Change: Added ability to read PCI config registers and indirect memory via the ESX private IOCTL.
Impact: bnx2 ESX only.
2. Change: Add reporting of MDI/MDIX status to ethtool.
Impact: Copper devices only.
bnx2 2.2.5b (Nov 18, 2013) =========================== Fixes ----- 1. Problem: (CQ71793) 5709 sometimes does not link up in 100Mbps forced speed.
Cause: PHY advertisement register needs to be set to 0 when speed is forced. The default advertisement register value is 10 Mbps and it will not link up when the speed is 100 Mbps.
Change: Set advertisement register to 0 when speed is forced.
Impact: 5709C forced speed.
bnx2 2.2.4g (Nov 07, 2013) =========================== Fixes ----- 1. Problem: PHY loopback test fails when set to 100Mbps on 5708 Copper.
Cause: Regression caused by enabling auto-MDIX (PHY reg 0x18 shadow 7 bit 9).
Change: Disable it on 5708.
Impact: 5708 only.
bnx2 2.2.4f (Oct 29, 2013) =========================== Fixes ----- 1. Problem: Netqueue didn't get stop and re-initialized properly during reset task, change coalece setting, and self test operations.
Cause: Normal Netqueue stop and re-initialized operations weren't executed while the device went through a full reset.
change: Added proper Netqueue stop/start operations in the above code paths.
Impact: ESX only.
cnic 2.5.18c (Oct 29, 2013) ============================ Enhancements ------------ 1. Change: Add signature to the iSCSI TX doorbell to prevent iscsiuio from getting the wrong value when using older kernel drivers.
Impact: bnx2x iSCSI only.
bnx2 2.2.4e (Oct 23, 2013) ============================ Enhancements ------------ 1. Change: (CQ69514) Enable auto-MDIX when autoneg is disabled by setting copper PHY register 0x18 shadow 7 bit 9.
Impact: All bnx2 copper devices.
2. Change: Display driver version in vmkernel.log during ESX fw dump.
Impact: ESX only.
package 2.78.33 (Sept 23, 2013) =============================== Fixes ----- 1. Problem: Package does not compile on Xen Server 6.2
Cause: kernel compatibility issue.
Change: Added new CFLAGS from bnx2x Makefile for bnx2x_compat.h.
Impact: All distributions. These fixes are only compatible with bnx2x 1.78.56 and newer.
bnx2 2.2.4d (Sept 12, 2013) ============================ Fixes ----- 1. Problem: cnic irq failed to run after esxcli network nic down/up event.
Cause: esxcli network nic down/up event causes bnx2 driver go through bnx2_close and bnx2_open. The sequence of events will re-allocate status block memory and the new status block memory address is not communicated to cnic after bnx2_open.
Impact: bnx2 ESX only.
cnic 2.5.18b (Sept 12, 2013) ============================ Fixes ----- 1. Problem: iSCSI does not work with bnx2x 1.78.52.
Cause: bnx2x doorbell change not compatible with existing iscsiuio.
Change: Pass modified iSCSI CID to iscsiuio for backwards compatibility.
Impact: bnx2x iSCSI.
2. Problem: Panic in cnic after ifdown/ifup bnx2x iSCSI device.
Cause: Accessing uninitialized FCoE EQ. Bug introduced in 2.5.17c which started using bnx2x NO_FCOE macro. cnic did not consistently use NO_FCOE, causing FCoE EQ to be accessed by mistake.
Change: Use NO_FCOE macro consistently in cnic code.
Impact: FCoE.
bnx2 2.2.4c (Aug 30, 2013) ============================ Enhancements ------------ 1. Change: Fix compile errors see on ESX * struct chip_core_dmp definition conflicts with bnx2x, scoped this struct to have a bnx2 prefix * Compiled FW dump for ESX5.5
Impact: bnx2 ESX only.
cnic 2.5.17c (Aug 30, 2013) ============================ Fixes ----- 1. Problem: cnic crash when shutting down 57811 device.
Cause: 57811 Chip ID not reconized by cnic.
Change: Re-structured code to use common bnx2x macros for Chip ID, port ID, pfid.
Impact: iSCSI and FCoE on all bnx2x devices.
bnx2 2.2.4b (Aug 12, 2013) ============================ Fixes ----- 1. Problem: CQ70286 IOVP: PSOD while executing NIC up/down command using esxcli.
Cause: New bnx2_free_irq() also disable MSIX/MSI on the device during bnx2_close. When bnx2_open is called, driver attempt to get INTA interrupt instead of MSIX/MSI interrupt.
Change: Don't disable MSIX/MSI on the device upon close.
Impact: ESX only.
2. Problem: WoL does not work during suspend if device is not up.
Cause: WoL setup skipped in bnx2_suspend() if device is not up.
Change: Always setup WoL in bnx2_suspend().
Impact: bnx2 suspend.
Enhancements ------------ 1. Change: Update 5709 firmware to 6.2.1.c to include mechanism to flush the iscsi OOO ring to silence some error messages about stale hardware index.
Impact: iSCSI on these bnx2x devices where the iSCSI license can only be fully determined after firmware is loaded.
2. Change: Changes to match the new 5709 6.2.1.c firmware to flush the iSCSI OOO ring.
Impact: 5709 iSCSI.
bnx2 2.2.3t (July 23, 2013) ============================ Fixes ----- 1. Problem: CQ70262 IVOP: PSOD HeavyIOChangeMTU test on 5709 card.
Cause: During ring size change, bnx2_free_irq() was called without checking reset_irq flag.
Change: Don't call bnx2_free_irq() if reset_irq flag is false.
Impact: ESX only.
2. Problem: (CQ69619) ethtool NVRAM operations fail when device is down.
Cause: Driver checks and prevents NVRAM operations when device is down.
Change: Remove the check. The driver now stays in D0 power state when the device is down and NVRAM operations are possible.
Impact: ethtool -e|-E
cnic 2.5.16j (July 23, 2013) ============================= Fixes ----- 1. Problem: (RHEL BZ 759217) System hangs when attempting iSCSI connections on 57711E.
Cause: iSCSI license changes from supported to unsupported between bnx2x probe and bnx2x open. bnx2i is unaware that the device does not support iSCSI and attempts to do offload which never completes. The recent change to eliminate symbol_get() to obtain bnx2x_cnic_probe() exposed the problem.
Change: Check iSCSI license again during ->drv_register_cnic(). If there is no iSCSI license, skip ->ulp_start().
Impact: iSCSI on these bnx2x devices where the iSCSI license can only be fully determined after firmware is loaded.
bnx2 2.2.3s (June 27, 2013) ============================ Fixes ----- 1. Problem: PCI shutdown function does not work on ESX.
Cause: system_state and SYSTEM_POWER_OFF not defined.
Change: Added compatibility code.
Impact: ESX only.
bnx2 2.2.3r (June 27, 2013) ============================ Enhancements ------------ 1. Change: (CQ68271, 68277) In order to support ethtool NVRAM operations when the device is down, the following changes were made:
- converted to use new WoL and PM kernel APIs - removed power state changes during open and close - added pci shutdown function to setup WoL during shutdown - converted to new style suspend/resume driver APIs
Impact: Everything related to WoL, shutdown, suspend, resume. Because of the significant changes, the system should be rebooted after running "make install" for the new driver. Without reboot, the new driver may not work as it is not aware that the older driver has put the device into D3hot state.
bnx2 2.2.3q (May 24, 2013) ============================ Enhancements ------------ 1. Change: Simplified compatibility code for driver section macros, __devinit, __devexit, etc.
Impact: None.
bnx2 2.2.3p (May 23, 2013) ============================ Fixes ----- 1. Problem: Bootcode firmware may not detect new message from driver. (VMWare reported issue)
Cause: The initial sequence number may not be unique enough.
Change: Read from the firmware mailbox and add one to it as the initial sequence number.
Impact: All devices.
Enhancements ------------ 1. Change: Made changes to compile on the latest 3.x kernels.
Impact: All.
cnic 2.5.16i (May 23, 2013) ============================= Fixes ----- 1. Problem: (CQ69177) MTU change causes PSOD at bnx2x_drv_ctl
Cause: The OOO handler was falsely triggered to handle OOO tx completions even when bnx2x has failed to allocate resources for the OOO ring. This has caused bnx2x to hit a NULL ptr dereference.
Change: Fixed the cnic OOO handler.
Impact: bnx2x iSCSI only.
cnic 2.5.16h (April 30, 2013) ============================= Enhancements ------------ 1. Change: Added max_fcoe_exchanges parameter so that bnx2fc can support multiple FCoE ports on a device.
Impact: FcoE only.
bnx2 2.2.3o (April 30, 2013) ============================ Fixes ----- 1. Problem: (BDKL225) __napi_schedule assertion when bnx2 switch from MSI to INTx.
Cause: NAPI was not disabled before IRQ is freed when switching from msi mode to INTA mode which prevents VMkernel from updating the stale napi->intr_cookie value.
Change: Disabled NAPI before free IRQ and then re-enable NAPI after chip is re-initialized. In addition, enabling of NAPI should always be done after chip_init().
Impact: All.
bnx2 2.2.3n (Mar 11, 2013) ========================== cnic 2.5.16g (Mar 11, 2013) ========================== Fixes ----- 1. Problem: cnic driver does not compile on XEN server.
Cause: Shared bnx2x_compat.h relies on some CFLAGs to compile properly on XEN server.
Cause: Firmware bug and cnic error handling bug for TCP_CLOSE ramrod.
Change: Added check for iscsi completion error when receiving the TCP_CLOSE ramrod completion.
Impact: bnx2x iSCSI only.
bnx2 2.2.3m (Jan 28, 2013) ========================== cnic 2.5.16e (Jan 28, 2013) =========================== Fixes ----- 1. Problem: (CQ67528) cnic/bnx2 crash when both drivers are loaded on some kernels.
Cause: Shared struct bnx2 compiled differently on bnx2 and cnic, causing cnic to reference the wrong field.
Change: Added bnx2_compat0.h to define the common CFLAGs that affect structure sizes for both drivers to include.
Impact: All (if cnic is loaded)
bnx2 2.2.3k (Jan 25, 2013) ========================== Fixes ----- 1. Problem: CNIC driver didn't get started after bnx2_open().
Cause: CNIC driver is stopped when bnx2_close() is invoked. However, there is no equivalent turn on mechanism when bnx2_open() is called. The issue prevent bnx2i to offload iscsi connections during session recovery.
Change: Added equivalent cnic start procedure in bnx2_open().
Impact: ESX only.
cnic 2.5.16d (Jan 25, 2013) =========================== Fixes ----- 1. Problem: (CQ67375) Unable to turn iSCSI TCP delayed ACK on after it's been turned off.
Cause: tcp_flags in cnic's socket structure not cleared between destroy and create calls.
Change: Clear tcp_flags during socket create call.
Impact: iSCSI only.
2. Problem: (CQ67306) iSCSI TCP delayed ACK not working.
Cause: Firmware HSI change.
Change: Adapted to new firmware HSI which is now defining delayed ACK globally for the HBA.
Impact: iSCSI only.
cnic 2.5.16c (Jan 15, 2013) =========================== Fixes ----- 1. Problem: cnic does not compile on SLES11SP2.
Cause: bnx2x_compat.h conflicts with SLES11SP2 header files.
Change: Modilfed Makefile to detect SLES distribution so that the proper CFLAG can be defined for bnx2x_compat.h
Impact: SLES distributions only.
cnic 2.5.16b (Dec 12, 2012) =========================== bnx2 2.2.3j (Dec 12, 2012) ========================== Enhancements ------------ 1. Change: (CQ60429, 66302) Simplify cnic probing by not using symbol_get(). symbol_get() is unreliable as it fails while the network driver is still initializing.
Impact: iSCSI and FCoE (driver loading and unloading).
Cause: Race condition during simultaneous remote reset and local TCP close/reset. This may be a partial fix and additional fixes in other areas/drivers may be necessary to completely address all symptoms.
Change: If remote reset is detected to be in progress during local close/reset, it will wait for outstanding RAMRODs to complete. Without the wait, bnx2i will proceed to destroy the connection while the SRCH_DELETE/TERM_OFFLOAD RAMRODs are still pending.
Impact: bnx2x iSCSI only.
bnx2 2.2.3i (Nov 05, 2012) ========================== Enhancements ------------ 1. Change: (CQ65960) Make minor compatibility changes to support RHEL6.4
Impact: None.
2. Change: Added support for latest 3.x kernels.
Impact: All supported kernels.
cnic 2.5.14c (Nov 05, 2012) ========================== Fixes ----- 1. Problem: (CQ65178) Panic when loading and unloading cnic with bnx2i and bnx2fc.
Cause: The iSCSI EQ does not get reset during cnic init. When we get the first cnic IRQ, the iSCSI EQ index may be non-zero in the status block, causing the cnic driver to dereference NULL pointer.
Change: Added code to clear the iSCSI EQ index in the STORM memory.
Impact: 10G iSCSI.
bnx2 2.2.3h (Oct 16, 2012) ========================== Fixes ----- 1. Problem: Netdump crash when runing with ESX6.0 OS.
Cause: bnx2 poll controller routine is not compatible with ESX6.0.
Change: For ESX6.0, bnx2 will use ESX poll controller for netdump.
Cause: There is race condition where netdev_watchdog() could erroneouly flag tx timeout in a small window when bnx2_netif_stop() disabled tx queue state while carrier is still on.
Change: Carrier must be turned off before netif_tx_disable() is called.
cnic 2.5.12e (Aug 22, 2012) ========================== Fixes ----- 1. Problem: (CQ 65270): bnx2x IRQ assert on 57712 and newer devices that support iSCSI only.
Cause: Not arming IRQ properly when detecting that the device does not support FCoE. Regression from cnic 2.5.12c enhancement #3.
Change: Added function pointer to arm IRQ correctly based on chip type.
Impact: iSCSI and FCoE on all 10G devices.
cnic 2.5.12d (Aug 21, 2012) ========================== Fixes ----- 1. Problem: (CQ 65249): cnic panic on functions that support FCoE only.
Cause: Code accessing iSCSI resources that aren't initialized or allocated on functions that don't support iSCSI.
Change: Check for valid UIO resource before trying to free it. Always initialize iSCSI OOO resources.
Impact: 10G iSCSI and FCoE.
bnx2 2.2.3d (Aug 15, 2012) ========================== Fixes ----- 1. Problem: (CQ 65163): unhandled NETQUEUE messages 16 and 17 seen in vmkernel logs
Cause: Not properly handling unsupported NetQueue ops
Change: Properly handle the NetQueue ops 16 and 17 without printing the warning message
Impact: ESX only
Enhancements ------------ 1. Change: Try to recover from PCI block reset during TX timeout. Red Hat users have reported PCI block resets that could not be recovered during tx timeout.
Impact: None.
2. Change: Added mk_kernel_patch.sh to patch bnx2 driver into kernel tree.
Impact: None.
cnic 2.5.12c (Aug 15, 2012) ========================== Enhancements ------------ 1. Change: Added firmware dump support for ESX6.0.
Impact: ESX6.0.
2. Change: Reduced maximum iSCSI abort delay to 5 seconds
Impact: iSCSI
3. Change: Allocate FCoE or iSCSI resources on a cnic only if the device supports the protocol. This will reduce memory consumption on multi-function devices.
Impact: iSCSI and FCoE
bnx2 2.2.3c (July 09, 2012) ========================== Fixes ----- 1. Problem: Unmapping the wrong DMA address in bnx2_free_tx_skbs() in rare cases.
Cause: Not skipping the last entry in the tx BD ring.
Change: Use the proper macro to get the next BD entry.
Impact: On systems with IOMMUs enabled, the bug can be triggered when doing resets (ifdown, MTU change) during heavy TX traffic.
cnic 2.5.12b (July 03, 2012) ============================= Enhancements ------------ 1. Change: Updated to bnx2x firmware 7.4.8 HSI for TX BDs.
Cause: Bug in cnic when max OOO resource is reached
Change: Initailized packet descriptor to fix the bug.
Impact: iSCSI only.
bnx2 2.2.3b (June 29, 2012) ========================== Fixes ----- 1. Problem: Compile error in RHEL6.x kernel and similar kernels.
Cause: skb_frag_size() compatibility code not detected properly.
Change: Fixed Makefile to detect it from skbuff.h
Impact: None.
bnx2 2.2.2b (June 24, 2012) ========================== Fixes ----- 1. Problem: (CQ63682)PSOD in ESX upon device open.
Cause: NAPI was not disabled properly upon device close. Thus, ASSERT occurs upon reopening device.
Change: Add NAPI disable upon close and add netif_tx_disable for both linux and ESX build.
Impact: bnx2.
2. Problem: Enableing RSS interferes with RX NETQ feature when compiled for ESX build.
Cause: RSS is enabled by default in bnx2. The RSS feature will lead to firmware bypass NETQ code path.
Change: Disable RSS by default when compiled for ESX.
Impact: ESX.
Enhancements ------------ 1. Change: Partial sync-up with upstream driver. Please see Changelog.
Impact: All
cnic 2.5.11c (June 12, 2012) ============================= Fixes ----- 1. Problem: (CQ62298 Partial fix) When running in INTA mode, MTU change does not work. iSCSI/FCoE does not resume after MTU change.
Cause: During mtu change, bnx2x does not know that cnic is no longer handling IRQs.
Change: Added a new flag to let bnx2x know that cnic is no longer handling IRQ during reset.
Impact: bnx2x iSCSI and FCoE.
2. Problem: (CQ62937) bnx2x asserts during iSCSI test with corrupted TCP NOP-IN.
Cause: Corrupted NOP-IN falls outside of TCP window, causing FW to go into OOO mode. TCP close with outstanding OOO causes problem and the close does not complete.
Change: FW change to return an error in this case and cnic driver change to handle this error by proceeding to clean up the connection.
Impact: bnx2x iSCSI.
cnic 2.5.11b (April 30, 2012) ============================= Fixes ----- 1. Problem: (CQ62298 Partial fix) Fix for CQ62026 in cnic 2.5.9d introduced a regression of clearing the CNIC_UP flag before all CIDs have been deleted. The regression is causing warning messges that some CIDs have not been deleted. After fixing this, we're still encountering further bnx2x error messages in the INTA code path.
Change: Wait for all CIDs to be deleted before clearing CNIC_UP flag.
Impact: iSCSI and FCoE on all bnx2x devices.
bnx2 2.2.1l (April 18, 2012) ============================ Fixes ----- 1. Problem: PSOD on ESX because of inconsistant NetQueue state when the NetQueues are allocated/freed out of order
Cause: The forced freeing of the NetQueue before the NetQueue allocation can cause the incorrect NetQueue to be freed and marked incorrectly.
Change: Remove the freeing of the NetQueue in the allocation path and allow the load balancer to control the error path when NetQueue's could not be allocated/freed.
Impact: ESX only.
cnic 2.5.10c (April 18, 2012) ============================= Enhancements ------------ 1. Change: Added iface_num parameter to cm_create() and iscsi_nl_send_msg()to support bnx2i 2.7.2.2b.
Impact: iSCSI only.
bnx2 2.2.1k (April 04, 2012) ============================ Enhancements ------------ 1. Change: Reduced code size of FTQ dump during tx_timeout.
Impact: None.
cnic 2.5.10b (April 04, 2012) ============================= Enhancements ------------ 1. Change: Added PCI pass through support for bnx2x E2/E3 devices.
Cause: cp->ctx_tbl is NULL during cnic_ctl() call with COMPLETION_CMD.
Change: cnic is registered with the L2 drivers before we allocate the cp->ctx_tbl so it is possible to get called while cp->ctx_tbl is NULL. Added check for CNIC_UP flag before proceeding to dereference cp->ctx_tbl. This together with the RCU code will completely fix the problem.
Cause: Middle-box test corrupts packets and causes iSCSI fw to generate 0x4 (NIC_ERR) completion code. This conflicts with new logic that uses NIC_ERR to convey parity error.
Change: Redefined parity error completion code to be 0x81 for L4, iSCSI, and FCoE.
Impact: FCoE and iSCSI.
bnx2 2.2.1g (Feb 28, 2012) ========================== Fixes ----- 1. Problem: Calling of bnx2_vlan_rx_kill_vid() is not rtnl_lock protected. Change: hold rtnl_lock when execute this routine under ESX4.0 and ESX4.1. Impact: ESX4.0/4.1 only.
bnx2 2.2.1f (Feb 8, 2012) ========================== Fixes ----- 1. Problem: (CQ61327) Unable to pass traffic on RHEL5.x
Cause: bp->num_rx_rings not initialized due to backport errors. This was introduced in 2.2.1e when adding ethtool -l|L support.
Change: Initialized bp->num_rx_rings to 1 on these older kernels.
Impact: RHEL5 and SLES10 only.
cnic 2.5.8f (Feb 06, 2012) ========================== Enhancements ------------ 1. Change: Added VLAN update from iscsiuio. This allows VLAN to be specified in iface.
Impact: iSCSI only.
cnic 2.5.8e (Jan 24, 2012) ========================== Enhancements ------------ 1. Change: Enhanced FCoE parity recovery by sending immediate FW_DESTROY completion with error during parity error recovery.
Impact: FCoE only.
bnx2 2.2.1e (Jan 24, 2012) ========================== Enhancements ------------ 1. Change: Added support for ethtool -[l|L]. Please refer to README.TXT for details.
Impact: 5709 with support for MSIX only.
cnic 2.5.8d (Jan 19, 2012) ========================== Enhancements ------------ 1. Change: Enhanced FCoE driver registration to provide FCoE capabilities to bnx2x driver.
Impact: Systems with Management support of these features. These changes were made to match bnx2x 1.72.07.
2. Change: (CQ60867) Backed out earlier changes related to this CQ. genksyms checksums are based on structure names and type names, so the scheme of using an identical structure with a different name will not work.
Impact: None.
cnic 2.5.8c (Jan 10, 2012) ========================== 1. Problem: (CQ60744) Lose connection to FCoE targets after parity error recovery.
Cause: (Partial) DISABLE_CONN SPQ message does not complete, causing delaying waiting for bnx2fc to timeout.
Change: Added immediate KCQ error completion for FCOE_DISABLE_CONN. when SPQ fails.
Cause: If a TCP connection fails due to parity error, termination sequence does not follow the expedited error recovery path. This causes unnecessary delay during parity error recovery.
Change: Set the HW_ERR bit when TCP connection fails due to SPQ error. Termination will then follow the expedited error recovery path.
Impact: iSCSI on bnx2x.
3. Problem: (CQ60867) Module versioning warning when installing cnic driver on SLES11SP2 without matching bnx2i/bnx2fc.
Cause: cnic_register_driver() stub in cnic.c does not have cnic_ulp_ops structure that matches inbox bnx2i/bnx2fc.
Change: Added dummy cnic_ulp_ops that match RHEL6.2 and SLES11SP2 structures.
Impact: None.
bnx2 2.2.1d (Jan 10, 2012) ========================== Fixes ----- 1. Problem: PSOD seen in TX handling in either bnx2_tx_int() or bnx2_start_xmit() routines
Cause: Memory re-ordering is occuring so that the TX BD is not updated before the ringing of the TX doorbell.
Change: On ESX the wmb() macro is defined to only as a compiler barrier. Redfine the wmb() macro to properly synchronize memory using the sfence instruction.
Impact: ESX only.
cnic 2.5.8b (Jan 05, 2012) ========================== Enhancements ------------ 1. Change: Added CNIC_CTL_FCOE_ENHANCED_STATS_CMD and CNIC_CTL_FCOE_CAPABILITIES_GET_CMD as stubs.
Cause: SPQ errors during parity error recovery was not propagated to L4 and ULP, causing unnecessary long timeouts.
Change: Added immediate KCQ error completion for L4 and iSCSI kwqes if SPQ fails.
Impact: iSCSI on bnx2x.
bnx2 2.2.1c (Dec 21, 2011) ========================== Fixes ----- 1. Problem: (CQ60281) BNX2 hang on ESX 4.1 when changing tx ring size with Ethtool.
Cause: BNX2 set_ringparam() ethtool ops callback attempts to hold rtnl_lock while vmlinux has already held this lock when when invoking this callback. This leads to deadlock situation and driver will hang forever.
Change: Make sure all ethtool ops callbacks don't hold rtnl_lock.
Impact: ESX only.
2. Problem: (BDKL87) PSOD in bnx2 start_xmit() path when stressing with change ring size script on ESX 4.1u2.
Cause: When using ESX4.0/4.1u0-u2, the vmkernel doesn't not check tx queue state properly in certain race condition. This can lead to bnx2 start_xmit() to deference NULL tx buffer.
Change: check tx queue state before proceed with stat_xmit().
Impact: ESX4.0/4.1u0-u2.
cnic 2.5.7h (Dec 08, 2011) ========================== Enhancements ------------ 1. Change: Added iSCSI and FCoE driver status and counters support.
Impact: Systems with Management support of these features.
2. Change: Added upstream patches to sync up with upsteam driver: net: treewide use of RCU_INIT_POINTER net: remove ipv6_addr_copy()
Impact: None.
bnx2 2.2.1b (Dec 08, 2011) ========================== Enhancements ------------ 1. Change: Added several upstream patches to sync up with upsteam driver: net: treewide use of RCU_INIT_POINTER bnx2: fix skb truesize underestimation net: Remove unnecessary driver assignments of ethtool_ringparam fields to zero
Impact: None.
bnx2 2.1.12b (Oct 14, 2011) =========================== Fixes ----- 1. Problem: (CQ59255) iSCSI warning messages appear and performance drops when connected to a lefthand target.
Cause: Packets with invalid TTT generate warnings and exception handling.
Change: Updated to 6.2.3 firmware for 5706 and 6.2.1.b for 5709
Impact: iSCSI
cnic 2.5.7g (Sep 23, 2011) ========================== Enhancements ------------ 1. Change: Added cnic_register_driver()/cnic_unregister_driver stubs so that depmod will not return errors if native bnx2i/bnx2fc drivers have not been updated.
Impact: None.
bnx2 2.1.11e (Sept 19, 2011) =========================== Enhancements ------------ 1. Change: Set the feature, NETIF_F_NO_SCHED, for ESX 5.0 and greater releases only
Impact: ESX only
Fixes ----- 1. Problem: Compile errors on some older kernels.
Cause: Compatibility API pci_is_pcie() requires bool type which may not be defined on older kernels.
Change: Moved bool type compatibility definition above pci_is_pcie().
Impact: None.
bnx2 2.1.11d (Aug 30, 2011) =========================== Enhancements ------------ 1. Change: Integrate Code Review Comments from VMware * Add feature flag to reflect if a device is compliant with network scheduling. * Conditionally move bnx2 drivers to high memory * Remove unused field/code
Impact: ESX only
2. Change: Remove unnecessary read of PCI_CAP_ID_EXP from upstream.
Impact: minor (5709 only).
cnic 2.5.7f (Sep 13, 2011) ========================= Fixes ----- 1. Problem: Duplicate cp local variable in cnic_shutdown_rings().
Cause: Coding error.
Change: Removed duplicate variable.
Impact: None.
cnic 2.5.7e (Aug 8, 2011) ========================= Fixes ----- 1. Problem: (CQ57498) System hangs during bnx2x parity error recovery.
Cause: cnic waits for RAMRODs to complete without timeout. During parity error recovery, all DMAs will stop.
Change: Added timeouts to all RAMRODs.
Impact: iSCSI and FCoE on bnx2x
cnic 2.5.7d (July 28, 2011) =========================== Enhancements ------------ 1. Change: Increased the max number of FCoE sessions to 1024.
Impact: FCoE.
bnx2 v2.1.11c (July 26, 2011) ============================ Enhancements ------------ 1. Change: Upstream sync to use ethtool_cmd_speed API.
Impact: None.
2. Change: Added memory barrier to sync transmit descriptor before updating TX mailbox. We believe that this may fix some very rare panics reported by VMWare.
Impact: bnx2 packet transmit.
cnic 2.5.7c (July 26, 2011) =========================== Fixes ----- 1. Problem: FCOE_DESTROY_FUNC ramrod not completing, causing timeout and OOO cleanup timeout during MTU change.
Cause: FCOE_DESTROY_FUNC was sent before all FCoE CIDs have been deleted.
Change: Wait for all (2 seconds delayed) FCoE CFC_DELETE ramrods to be completed before sending FCOE_DESTROY_FUNC.
Impact: FCoE only.
cnic 2.5.7b (July 19, 2011) =========================== Enhancements ------------ 1. Change: Re-instated vlan_id in ->indicate_netevent(). It is needed by bnx2fc to handle NETDEV_UNREGISTER on VLAN devices.
Impact: bnx2fc.
2. Change: Allocate FCoE CID space only on E2+ devices.
Impact: None.
bnx2 v2.1.11b (July 19, 2011) ============================ Enhancements ------------ 1. Change: Added tx_timeout error handling and made it common with VMWare code.
Impact: bnx2 NETDEV WATCHDOG error handling
2. Change: Fix compile errors on the latest net-next upstream kernel.
bnx2 v2.1.10d (July 12, 2011) cnic 2.5.6c (July 12, 2011) ========================================================= Fixes ----- 1. Problem: Not compiling on 3.0.0 kernel.
Cause: Makefile not recognizing the 3.0.x kernel
Change: Modified Makefile and sync'ed with upstream drivers.
Impact: None.
bnx2 v2.1.10c (July 1, 2011) ============================ Fixes ----- 1. Problem: Not compiling on older kernels (such as RHEL5.4) and newer kernels (such as 2.6.36)
Cause: Problems with compatibility code.
Change: Fixed compatibility code.
Impact: None.
bnx2 v2.1.10b (June 30, 2011) ============================ Enhancements ------------ 1. Change: Added more complete MCP dump during error conditions.
Impact: None.
2. Change: Modified driver messages slightly to match upstream format (by using netdev_printk, netdev_err, etc).
Impact: None.
Fixes ----- 1. Problem: Not reading iSCSI license on 570x devices reliably.
Cause: We were reading from the CP scratch pad before the CP firmware is loaded.
Change: Read from MCP shmem location instead.
Impact: 1G iSCSI on bnx2 devices.
cnic 2.5.6b (June 30, 2011) ============================ 1. Problem: (CQ56522, CQ56259) Unable to connect to iSCSI target, bnx2x firmware assert during iSCSI connection
Cause: iSCSI L2 ring CID has been changed in bnx2x 1.70.14. uIP is using a hardcoded value of 0x11.
Change: cnic now passes the CID to uIP.
Impact: iSCSI on bnx2x devices.
2. Problem: (CQ56230) Cannot compile on some 32-bit systems.
Cause: Passing 64-bit NULL pointer as 32-bit 0 dma_addr_t value.
Change: Use 0 instead of NULL for dma_addr_t values.
Impact: None.
cnic 2.5.5b (June 22, 2011) ============================ Enhancements ------------ 1. Change: Added WWN info to cnic_eth_dev. This is a temporary solution until ndo_fcoe_get_wwn() is implemented.
Impact: None.
bnx2 v2.1.9b (June 22, 2011) ============================ Enhancements ------------ 1. Change: Added del_timer_sync() in bnx2_remove_one() from upstream commit 8333a46ad3877485e4d67ef499c6dda36bfd1f9a. See ChangeLog for details.
Impact: None.
bnx2 v2.1.8c (June 16, 2011) ============================ Enhancements ------------ 1. Change: In ESX, bnx2 will setup int mode during .probe time. However, the dev->name will be finalized only when pci_announce_device is done. So, we assign irq->name in bnx2_request_irq instead of in bnx2_setup_int_mode.
Impact: ESX only.
cnic 2.5.4b (June 1, 2011) ============================ Fixes ----- 1. Problem: (CQ55915) iSCSI does not connect on 57800 in 4-port mode.
Cause: cl_qzone_id was wrong on the 3rd and 4th port. uIP also has some problems determining 4-port mode.
Change: Fixed the QZONE_ID macro.
Impact: bnx2x iSCSI.
bnx2 2.1.8b (June 1, 2011) ============================ Fixes ----- 1. Problem: (CQ55422) NCSI firmware version displayed backwards on PPC.
Cause: Endian bug when reading the data from shared memory.
Change: Fixed byte swapping issue.
Impact: None.
2. Problem: bnx2 does not compile on some PPC distros.
Cause: pci_enable_pcie_error_reporting() not properly defined in some distros.
Cause: Added #ifdef to prevent compiling pci_enable_pcie_error_reporting() on PPC since it uses EEH instead of AER.
cnic 2.4.5b (May 16, 2011) ========================== Enhancements ------------ 1. Change: Check CFC delete error code during completion. If it is set, do not reuse the CID. This change is only compatible with bnx2x 1.64.30 or newer.
Cause: TCP reset request may not complete if there is a race with firmware receiving a remote RST.
Change: Added code to handle TCP reset racing with remote RST and TCP close racing with remote FIN.
Impact: iSCSI
cnic 2.4.3b (April 28, 2011) ============================ Fixes ----- 1. Problem: cnic may lose interrupts after processing 64 kcq entries.
Cause: The driver handles a maximum of 64 entries before calling the ulp drivers. If the chip has more entries, the driver does not handle the rest but acknowledges the latest status block index.
Change: Changed the logic to keep looping until all kcq entries are handled.
Impact: iSCSI and FCoE on all devices.
cnic 2.4.2b (April 21, 2011) ============================ Fixes ----- 1. Problem: (CQ54715, CQ54717) XSEMI parity error detected during iSCSI login on 57712 in NPAR mode.
Cause: Statistic counter ID greater than MAX_STAT_COUNTER_ID_E2 in client init data for iSCSI L2 ring.
Change: Check client ID against MAX_STAT_COUNTER_ID_EXX before enabling statistics.
cnic 2.4.1c (April 11, 2011) ============================ Fixes ----- 1. Problem: (CQ49586) iSCSI reboot test fails after a few iterations.
Cause: TCP port 60000 is used every time during boot. During reset, the TCP connection is never terminated so using the same port to connect to the target during reboot will not work.
Change: Added randomization of the first TCP port to use.
Impact: iSCSI.
bnx2 v2.1.6b (April 6, 2011) ============================ Enhancements ------------ 1. Change: Get iSCSI license information to prevent cnic from registering if there is no license. This will make it consistent with 10G behavior.
Impact: iSCSI only.
cnic 2.4.1b (April 6, 2011) =========================== Fixes ----- 1. Problem: (CQ53236) FCoE HBA not functional after reloading bnx2x.
Cause: In some distros, NETDEV_UP can happen immediately after NETDEV_REGISTER while bnx2x module is still in init state. At this time, cnic will not be able to symbol_get() from bnx2x, preventing the cnic from registering.
Change: Check all events, and we should be able to catch NETDEV_CHANGE abd register cnic.
cnic 2.4.0b (Mar 29, 2011) ========================== Enhancements ------------ 1. Change: Updated cnic to with with bnx2x 1.70.x and added support for 578xx devices.
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: 57712 iSCSI and FCoE.
bnx2 v2.1.5c (Feb 15, 2011) cnic 2.3.5c (Feb 15, 2011) ====================================================== Enhancements ------------ 1. Change: Updated 5709 firmware to 6.2.1a, with netq fixes and iSCSI performance regression fixes.
Impact: 5709.
bnx2 v2.1.5b (Feb 08, 2011) cnic 2.3.5b (Feb 08, 2011) ====================================================== Fixes ----- 1. Problem: iSCSI does not connect in DCB environment.
Cause: iSCSI packets are tagged with the wrong ethertype.
Change: Added initialization of xstorm's reserved_vlan_type field.
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.
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.
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: 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
bnx2 v2.0.11b (Jan 28, 2010) cnic 1.10.2b (Jan 27, 2010) ======================================================== Enhancements ------------ 1. Change: Saved bnx2 statistics block before MTU change, ring change, etc.
Impact: bnx2 statistics.
bnx2 v2.0.10b (Jan 12, 2010) cnic 1.10.1b (Jan 12, 2010) ======================================================== Enhancements ------------ 1. Change: Improved cnic's MTU change/reset logic to fix multiple problems in VMWare.
Impact: iSCSI.
2. Change: Converted to bnx2x T6.0 HSI.
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 ------------ 1. Change: Improved rx performance by prefetching next entry's descriptor header and SKB.
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.
Impact: 5709 flow control.
bnx2 v2.0.6b (Dec 4, 2009) cnic 1.9.11b (Nov 19, 2009) ======================================================= Fixes ----- 1. Problem: (CQ44801) Unable to compile bnx2 on most 2.6 kernels.
Cause: print_mac() kernel compatibility not defined correctly.
Fix: Simple compatibility fix.
Impact: None.
bnx2 v2.0.5b (Dec 4, 2009) cnic 1.9.11b (Nov 19, 2009) ======================================================= Enhancements ------------ 1. Change: Sync'ed up with latest upstream bnx2 driver. Please see ChangeLog for details.
Impact: Yes, Linux and VMWare.
bnx2 v1.9.42b (Dec 1, 2009) ======================================================= Fixes ----- 1. Problem: Compile error against the VMware ESX 4.0 DDK
Cause: vmk_IscsiNetHandle is not defined with the VMware ESX 4.0 DDK
Change: Added compile flag
Impact: None.
Enhancements ------------
1. Change: Add BMAPILNX ioctl to allow for FW upgrade
2. Problem: (CQ42096) iSCSI sessions do not recover after running selftest/ifdown/etc with max sessions connected.
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.
bnx2 v1.9.40b (Nov 18, 2009) cnic 1.9.10b (Nov 12, 2009) ======================================================= Fixes ----- 1. Problem: (CQ44528) Kernel runs out of memory after load/unload bnx2.
Cause: RX SKB buffers were not freed.
Change: Fixed the regression introduced by VMWare development.
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.
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.
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:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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().
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.
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.
v1.1.15 (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.
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.

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.
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.

Introduced: 1.78.23.
Relevance: BCM54618SE.
4. Problem: CQ72188 - 578xx fails to link with KinnexA SFP+T (1GBT) module. This fix handles only the link issue, assuming the SFP EEPROM is accessible, which is another aspect of the problem, handled in MFW 7.10.04.
Change: Reset TX_EN when RJ45 SFP module is detected.
Introduced: T7.8.
Relevance: SFP-RJ45 module.

4. Problem: BZ920329,1022730 (RH) - PCIe AER is not configured properly.
Change: Add missing OS calls to enable error reporting and perform cleanup after an error is handled.
2. Problem: CQ70554/CQ71071 - Failed to acquire 1G link over CL37 against 1Gb switch. This issue happens when the device is in KR mode, and the switch advertises only 1G link speed over CL37.
Change: To solve this, the auto-detect mode was enabled in the Warpcore allowing it to select the higher speed protocol between 10G-KR (over CL73), or go down to 1G over CL73 when there's indication for it.
Introduced: Day 1.
Relevance: 578xx-KR.
3. Problem: When removing bnx2x while there is a mix of passed through and non passed through VFs, the next bnx2x probe will hang when VF devices are probed. Older OS (e.g. RH < 6.3 and SLES < 11SP3) have this problem even w/o passedthrough VFs.
Change: Disable VF access at bnx2x remove, so when VFs are probed again they can't access the device.
Introduced: 1.78.00.
Relevance: SR-IOV.
4. Problem: CQ68627 - Incorrect port value is displayed for specific Passive DAC (Direct Attached Cable) with missing Passive indication in it's EEPROM.

Change: Avoid changing any link parameters when checking TX_FAULT indication when physical link is down.
Change: Change printing scheme, as flow is possible in MF UNDI.
Introduced: 1.78.24.
Relevance: Multi-function UNDI.
9. Problem: CQ71629 - self-test, mtu change, other ethtool operations cause 'timeout waiting for state X' message to appear, and device may be not functional.

Change: Set the parsing buffer descriptor with the source MAC.
Change: Protect statistics DMAE flow with global DMAE lock.
Introduced: 1.78.00.
Relevance: SR-IOV.
3. Problem: Driver sets NETIF_F_HIGHMEM only if setting 64-bit DMA mask succeeded. This is wrong, as this flag indicates whether the device/driver can handle skbs located in high memory, and the conditional setting may result with unnecessary memory copies.
Change: Set NETIF_F_HIGHMEM in dev_featrues unconditionally.
Introduced: Day 1.
Relevance: All.

3. Problem: At insmod driver would clear all the bits of the recovery register of that engine. In Physical Device Assignment this could lead to the recovery bit of a loaded PF (on another VM) to be cleared, leading to recovery taking place while a PF is active. This could certainly crash a VM, and perhaps also the HyperVisor.
Change: Do nothing with the recovery reg at insmod. Driver sets it's bit at nic_load, resets it at nic_unload, and if a VM crashes ungracefully, bootcode clears the bit at pulse timeout.
Introduced: 1.72.03.
Relevance: Recovery Flow in Physical Device Assignment.
4. Problem: At previous driver unload flow (removing the initialization remnants after chip was initialized by a driver from which control was wrested such as kdump in pda, or after undi driver) condition to activate FLR was wrong, resulting with FLR never taking place (and driver load taking place after timeout, disregarding the fact that the function was not reset). Errors in FLR activation led to function not acking the unload command towards mcp, leaving the function disabled.
Change: Fix FLR activation condition and error handling in previous unload flow.
Introduced: 1.72.13.
Relevance: Physical Device Assignment.
5. Problem: No connectivity between VF and its host PF when in single function mode even if tx-switching module param was set.
Change: Add the source and dest mac addresses to the parsing BD if the tx-switching module param was set (this was already done in switch independent multi function mode, so problem only occurs in single function mode.

3. Problem: Once the first VF interface is loaded, fcoe non-offloaded stats are no longer collected, and PF issues stats requests for the first VF address even after it is unloaded.
Change: Properly position VF stats requests on ramrod with respect to FCOE stats requests.
Introduced: 1.74.02.
Relevance: SRIOV.
4. Problem: CQ64670 - If there are more than 64 cids for PF (e.g. 64 queues for PF plus a fwe for iscsi or fcoe, or when multi cos is supported when there 22 or more pf rx queues) the pf cids overspill into VF space, causing misinterpretation of PF completions as belonging to VF (can lead to HW assert, kernel null pointer dereference, etc).
Change: Enlarged the PF queues space to 256. This should cover any known configuration. Added logic to ensure that even if this barrier is breached by number of PF queues, SRIOV will simply be denied to the PF, rather than crashing catastrophically.
Introduced: 1.74.02.

Change: Close and open NIG-BRB gates only during when driver loads and unloads respectively.
Introduced: 1.74.02.
4. Problem: If no VFs were allocated to a PF with SRIOV capability, driver would attempt to dereference a null pointer when setting up a queue if a VF was loaded.
Change: Gracefully handle no resources.
Introduced: 1.74.04.
Enhancements: ------------- 1. Request: FW - change ETS default settings to fairness between traffic classes (rather than strict priority).

CQ63785 - Intermittent Driver Assert after configuring IP/Vlan information on device. The root cause is insufficient gate closure between the NIG to the BRB during link flap avoidance. It used to rely on specific filters, which didn't capture all traffic.
Change: Close the NIG-BRB gate during LFA reset to prevent packets flowing in before BRB is reset.
Introduced: 1.74.02.
Relevance: All.
Version 1.74.02 (Jun 03, 2012) ============================== Internal FW 7.4.4
Fixes: ------ 1. Problem: Possible crash when doing ethtool -L while CNIC is up.
Change: Indicate the updated number of CIDs and ILT lines to CNIC during NIC load.
Introduced: 1.72.51.
Relevance: All.
2. Problem: Warning kernel logs might be displayed during probe, indicating that number of MSIX vectors in IGU is different than the value advertised in PCI config space. This warning can be displayed due to new scheme used in MFW T7.4.
Change: Remove that warning.
Introduced: 1.70.23.
Relevance: (1) MFW T7.4 is used AND (2) SRIOV is enabled in nvram AND (3) MF mode or 4 port mode is used.
3. Problem: Nic load takes long time and might fail when using MFW T7.4, as driver assumed wrongly that all status block advertised to it were allocated by the MFW (which is wrong with new MFW scheme).
Change: Assume number of status blocks is the minimum between the value advertised in PCI and the actual allocation found in IGU scan.
Introduced: 1.72.51 (when forcing of maximum 16 SBs was removed).
Relevance: (1) MFW T7.4 is used AND (2) SRIOV is enabled in nvram AND (3) MF mode or 4 port mode is used.
4. Problem: CQ63210 - Ethtool -A fails to change pause parameters correctly.
Change: Set requested flow control prior to the interface load.
Introduced: Day one.
Relevance: Boards with autoneg capabilities.
5. Problem: CQ63403 - Under low memory condition, there is a flow which may cause kernel to crash: 1. Device must be in operational state (UP). 2. Changing device parameter fails due to insufficient memory. 3. rmmod or 'ip link ethX down' leads to crash.
Change: Update state on memory allocation failure; prevent accessing uninitialized structure.
Introduced: 1.70.06.
Relevance: Low memory conditions.
6. Problem: CQ63429 - Probe fails due to memory allocation failure when using MFW T7.4.
Change: Move sp_objs, fp_stats and TPA structures out of fp structure, to force contiguous memory allocation to always be smaller than 128KB.
Introduced: day 1 with MFW T7.4.
Relevance: Low memory conditions.
7. Problem: CQ63630 - Packets smaller than 92 bytes ignored by kernel when MTU > 1500 on kernels 3.3 and above.

Relevance: All.
Enhancements: ------------- 1. Request: Added EEE (802.3az) support to 578xx boards with 84833 phys.
2. Request: CQ63159 - Add basic Link Flap Avoidance support. Whenever link toggles, the requested link parameters are saved in a shared memory and are used to determine the conditions for LFA to occur. LFA can be achieved only in case all of the following terms take place: 1. MFW release used is 7.4.2 and above. 2. Requested Link Speed, Duplex, Speed Capability Mask and Requested Flow Control are the same as the saved ones. Note that in case LFA conditions are not met, link should be re-initialized and flapped like before.
3. Request: When link speed is autoneg, and flow control selected is autoneg as well, apply the RX/TX parameters of the ethtool -A as the advertised ones.
4. Request: Alpha support of SRIOV. Bnx2x can now drive a regular physical function, an sriov virtual function, or a hyper-visor physical function. This is determined according to: 1. If num_vfs module parameter is supplied then the pf is a hyper visor. In the proper environment (kernel version, iommu, flr capabilities, etc) it will add 'num_vfs' virtual functions to the pci device tree. If the environment is not SRIOV friendly the PF will act normally. 2. If the chip-id belongs to a virtual function then the function is a VF and the driver will treat it as such. Such devices can only be created in the fashion described above. 3. Otherwise, the function is a normal PF.

Enhancements: ------------- 1. Request: Wait for all 64 read tags from PCI to complete before performing parity recovery, instead of 32 tags as done today.
2. Request: Add support for external loopback test in ethtool self-test. When in MF-mode, indicate to the user that only online tests are performed. Reduce the number of tests by '1' in upstream version (as idle-check is not performed).
3. Request: Make the transmission queues adjacent (such that 'real_num_tx_queues' is the real number and there are no holes). Remove the workaround to flush all high queues during NIC load.
4. Request: Update CDU memory allocation to support up to 8 memory regions (rather than a single contiguous memory region). Reduce CDU ILT page size to 32KB.
5. Request: Add support to 57811.
6. Request: Change non-eth CIDs to start right after the eth CIDs (rather than at 48).

Fixes: ------ 1. Problem: CQ62046 - No link on 57712 + 8727 designs in which the TX laser is controller via GPIO, after T6.0 drivers/MFW were loaded previously without reboot. On these designs the TX_LASER is enabled by logic AND between the PHY(through MDIO), and the GPIO. When old driver which doesn't support these designs is used, it disables the MDIO part, thus the GPIO control has no affect.
Change: Enable the TX_LASER on the PHY for those design to enable the GPIO control it.

Relevance: All.
2. Problem: CQ62046 - No link on 57712 + 8727 designs in which the TX laser is controller via GPIO, after T6.0 drivers/MFW were loaded previously without reboot. This issue occurs since old drivers control the 8727 TX laser only by changing PHY register, and new drivers assumed this register had a default value, despite that this register is not actually controlling the TX laser in those designs. Note that this issue is not likely to occur because T6.0 driver don't support these kind of boards, and loading new drivers afterwards without reset, is not common practice.
Change: Check SW flag instead of querying the TX_DIS register.
Introduced: 1.62.01.
Relevance: BCM8727 designs with GPIO controlling the TX laser.
3. Problem: insmod bnx2x more than twice may causes MCP assert during initialization of device.

Introduced: 7.0.0.
Relevance: All.
5. Problem: When a TPA aggregation is open and a packet is accepted with timestamp OOO, the new packet begins a new aggregation instead of being indicated separately.
Change: (FW ETH) Fix the relevant firmware flow.
Introduced: 1.72.09 (FW 7.2.14).
Relevance: All.
6. Problem: CQ61596 - There exists a corner case where firmware will send out only a single 'pure ACK' (TCP acknowledgement segment that has no payload) while 255 or more 'pre ACKs' and a 'delayed ACK' are queued and awaiting transmission. The other ACKs in the queue are sent with a payload of one byte and all have identical sequence number and valid TCP/IP checksum. When the very next TCP/IP packet is sent for the offloaded connection, the receiver will trim a single byte off the incoming packet because of the ACK received with payload of one byte.
Change: (FW iSCSI) Fix the relevant firmware flow.
Introduced: 1.62.01 (iSCSI FW 6.2.1).
Relevance: iSCSI only.
7. Problem: FW statistics per queue does not increasing in queue counters, but properly increasing in device counters.

Introduced: 1.72.09.
Relevance: All.
8. Problem: CQ61763 - parity recover might fail on devices with two ports on the same path.

Introduced: day one.
Relevance: 57710 + 57711 + 4 port devices.
9. Problem: CQ60448 - Rare case of no link due to missed interrupt may occur due to a race condition between acknowledging the IGU via the BAR and restoring the NIG interrupt mask via the GRC.

Change: Restored the MODE_LED_OFF mode to explicitly keep the LEDs off.
Introduced: 1.72.07.
Relevance: LED manipulation for 54616/18 and 8727 PHYs.
2. Problem: When getting / setting the number of queues via ethtool -l/L need to use 'combined' rather than 'rx'/'tx', as we we don't have independent rx and tx queues. The number of rings cannot exceed the number assumed during probe, as there will not be msi-x vector or napi object to the extra rings. When waking / starting the entire range of tx rings (which is 16*coses + non-ethernet) we may get old transmit requests on non-existing queues.
Change: Use the 'combined' field rather than the 'rx'/'tx' fields. Limit the number of rings to the number assumed during probe. When waking / starting the tx rings start only the 'real' rings (and not the entire range).
Introduced: 1.72.04.
Relevance: All.
3. Problem: CQ61532 - System halts when driver is loaded after fan failure has occurred. This can be seen also after reboot in fan failure status. This problem happens in 578xx only where the MFW stops the clocks which prevents the host to map the PCI IO registers to BAR0, and cause fatal error.
Change: MFW signals the fan failure by setting the PCI version number to 0xff (reflected in PCI address 0x8), thus allowing the driver to check this failure before mapping the bar. Fix requires MFW version 7.2.15 (and above).

Relevance: 578xx blade designs.
8. Problem: skb truesize is under estimated.
Change: bnx2x allocates a full page per fragment. It should account in skb->truesize, the size of the fragment, not the used part of it.
Introduced: Day One
Relevance: All.
9. Problem: 84833 PHY FW command handler interface requires further refinement as they don't seem to work.
Change: Made further adjustments and consolidated the command handler routine (in anticipation for other commands besides auto-grEEEn)).
Introduced: Version 1.70.50.
Relevance: 84833 PHY.
Enhancements: ------------- 1. Request: Add LED functionality to 54618SE PHY based boards.
2. Request: Put 84833 PHY in super isolate mode regardless of the strapping pin. The PHY stays in this mode until driver is loading up.
Relevance: 84833 PHY only.

Introduced: Version 1.60.28.
Relevance: Optic ports with DAC.
Enhancements: ------------- 1. Request: Immediately return an error from the bnx2x_cnic_sp_post() if we are in the middle of the parity error recovery flow. This will significantly speed up the CNIC_STOP command flow when called in the parity recovery context.
Relevance: CNIC only.
2. Request: Allow DCBNL functionality for RHEL6.1 and RHEL6.2.
3. Request: Changed 'pri_map' module parameter to control mapping from priority to traffic class instead of deprecated role in SAFC configuration.
Version 1.70.51 (Sep 13, 2011) ============================== Internal FW 7.2.2
Fixes: ------ 1. Problem: Forced 100M speed cannot pass traffic with 578xx+84833.
Change: Configure the Warpcore to SGMII auto-neg when interfacing the 84833 PHY.
2. Problem: Cannot establish link with 84833 PHY using PHY FW v1.27.
Change: The FW has been changed to fully support superisolate mode. That requires the PHY initialization sequence to change.
Introduced: Day 1
Relevance: 84833 PHY, PHY FW v1.27 is required.
3. Problem: Overflow occurs during init, when generating statistics ramrod toward the FW (writing to index outside of array bounds).
Change: Increase number of elements in the array inside struct bnx2x_fw_stats_req.
Introduced: Day 1.
Enhancements: ------------- 1. Request: Collect FCoE statistics from FW (both offloaded and non offloaded), and add them to the statistics response toward the MCP in NPAR-SD mode. These statistics are not counted in the ones published to ethtool.

Introduced: 1.70.27.
5. Problem: On-chip TCP connection establishment on iSCSI connections is broken.
Change: Fixed in FW 7.2.2.
Introduced: In FW 7.2.1.
Relevance: iSCSI only.
Enhancements: ------------- 1. Request: Reduce power consumption for 57810 fan failure by: * Powering down the Warpcore. * Kill clocks to all driver present blocks. * Clear BME(Bus Master Enable) and MS(Memory Space).

2. Request: Prevent link flap on 1G copper ports when driver unloads in case the PHY is already initialized and link is up.
Relevance: 57800 + 5461x.
Version 1.71.00 (Sep 02, 2011) ============================== Internal FW 7.2.1
Fixes: ------ 1. Problem: Driver compilation failed on 2.6.38.x kernels.
Change: Fix compat for these kernels.
Introduced: 1.70.21.
2. Problem: Error messages "FATAL HW block attention set2 0x20" in the kernel log on specific systems.
Change: Recoverable LCRC errors due to not masking CPL_OF caused the print while it should be ignored.
Introduced: Day one.
Relevance: 57710 and 57711.
3. Problem: PCI scan could lead to GRC read.
Change: Second function indirect windows were not cleared by the driver since the driver used the port index before it was initialized and therefore cleared only function 0. Since the driver is not using these indirect windows, it will clear them all.
Introduced: Day one.
4. Problem: CQ57061 - GRC timeout messages appear on some systems during driver load.
Change: Take HW LOCK before resetting the HW, which prevents from undi_unload reading registers while block is in reset state.
Introduced: Day one.
5. Problem: Compilation failed on SLES11 SP1 update 1.
Change: Fix conflict on backported feature in bnx2x_compat.h.
Introduced: 1.70.20.
Relevance: SLES11 SP1 update 1 only.
6. Problem: The GPHY ports are not completely powered down on driver unload if the GPHYs have no external pins to bring them to reset state. As a result, their link partner may still see link.
Change: Put the GPHY in low power mode.
Introduced: 7.0.0.
Relevance: T0000G boards.
7. Problem: CQ56991, CQ57007 - PFC pauses non pausible traffic. This was because FW was configured to work in STATIC_COS on 57712 and 578xx regardless of kernel version. In kernels where multiple traffic classes are not supported this essentially blocked network traffic from being assigned any tc other than 0. If pausible traffic was assigned tc 0 the network traffic would necessarily collide with it.
Change: Configure FW to work in STATIC_COS only in kernels which support multiple traffic classes.
Introduced: 1.70.15.
Relevance: 57712 and 578xx on kernels before 2.6.39.
8. Problem: CQ57469, CQ57377, CQ56861, CQ57296 - CFC HW attention, XSTORM assert or kernel panic when changing the MTU under the TCP traffic (on the Tx side). Tx queues were stopped before bp->state was changed to a value different from BNX2X_STATE_OPEN, which allowed the bnx2x_tx_int() called from the NAPI context to re-enable it. This then allowed the netdev->ndo_start_xmit() to be called in the middle of the function reset and rings freeing, which caused the above failures.
Change: Change bp->state to a value different from BNX2X_STATE_OPEN BEFORE disabling the Tx queues in order to restore the protection against the above race in the bnx2x_tx_int().
Introduced: In 1.70.16 in the fix for CQ56438.
9. Problem: CQ57566 - During link down event "stats updated but no MAC active" messages appear in system log.
Change: Lowered the debug level of the message.

Change: Adjust number of VNICs for 4-port devices.
Introduced: In 1.70.00.
Relevance: 578xx 4-port.
18. Problem: CQ56409, CQ57534 - Initiator periodically sends out Discovery Solicitation after login is established. This was caused by a missing VLAN filtering on the bnx2fc side. To enable such a filtering on the ESX bnx2fc needs to be aware of the currently configured VLANs on the CNA device.
Change: Expose the CNA VLANs configuration to the CNIC.
Relevance: FCoE on the ESX only.
Introduced: Day one.
19. Problem: Compilation failed on kernel-3.0.x.
Change: Fix compat.h.
Introduced: Day one.
20. Problem: Improper RX ring configuration showed in some case via ethtool -g.
Change: Store current device configuration and pass to ethtool handler.
Introduced: 1.64.14.
21. Problem: Degradation in latency benchmarks noted (multiple TCP_RR). This was because driver configured FW to use the same state machine for rx and tx indices in status block.
Change: Use.seperate state machines for tx and rx.
Introduced: 1.60.00.
22. Problem: Forced half duplex link may not be supported.
Change: Clear full duplex bit in Warpcore when configuring forced link.
Introduced: Day 1.
Relevance: 578x0 + 84833, no exposure to 54616S/18SE PHY because it is configured as SGMII interface, not XFI.

Introduced: Day 1.
Relevance: 84833 PHY.
25. Problem: 84833 can't link up at 10G after the link went down from sub-10G.
Change: Re-enable 10G advertisement on every driver load instead of relying on hardware default.
Introduced: Day 1.
Relevance: 84833 PHY.
26. Problem: 84833 PHY FW command handler interface changed (needed for (auto-grEEEn and RJ45 pair swap).
Change: Made register offset adjustments to accommodate the new interface.
Relevance: 84833 PHY.
27. Problem: CQ58086 - on 578xx B0 ETS BW 0% is not allowed by driver.
Change: Provide alternative HW configuration for this case.
Introduced: 1.70.00.

32. Problem: Compilation failed when FCOE selected but FCOELIB is not in kernel config.
Change: Fix #if condition.
Introduced: 1.70.00.
Relevance: Specific kernel configuration.
33. Problem: IP and TCP ECN related TPA aggregation rules do not comply with LRO requirements. Firmware followed requirements for RSC which are incompatible with LRO requirements: 1. Allow TPA aggregation even if TCP ECE and CWR flags are set. 2. Allow TPA aggregation only if IP ECN CE and ECT bits are either 00 or 11.
Change: Fixed in FW 7.2.0. Firmware now allows TPA aggregation only if: 1. TCP ECE and CWR are both 0's. 2. IP ECN CE and ECT bits are other than 11.
Introduced: Firmware version 6.4.0.
34. Problem: CQ56960 (iscsi) - Arrival of un-solicited ASYNC message causes firmware to abort the connection with RST.

Introduced: Day one.
3. Problem: No flow-control on 578xx when link is up at 1G and below.
Change: Add pause functionality to UMAC
Introduced: 7.0.0.
Relevance: 578xx
4. Problem: CQ56991, CQ57007 - Networking traffic priority was mapped to the COS configured at startup which was 0 by default. If FCOE or ISCSI were configured by DCBX negotiation result to COS 0 the network traffic would cause drops on a dropless traffic class and could foul up ETS or PFC.
Change: When DCBX negotiation result occurs configure all priorities other than FCOE and ISCSI to the Networking COS.
Introduced: 1.70.15
Relevance: 57712/578xx with DCB support.
5. Problem: CQ57063 - tx checksum offload feature would not turn off when 'ethtool -K eth tx off' was used.
Change: Since at startup bnx2x declares support for ipv4 and ipv6 checksum offload, connect the ethtool ipv6 set checksum premade op to the set_tx_csum op which affects both ipv4 and ipv6 instead of the ipv4 op which affects only ipv4.
Introduced: 7.0.0.
6. Problem: CQ56294 - Incorrect Remote fault detection may lead to link down on 5771x fiber devices.
Change: Fix LSS fault mechanism to detect remote fault and transmit local fault through the BMAC. This change requires leaving the BMAC out of reset in case link of 10G goes down

Enhancements ------------ 1. Request: Use vmalloc for a zlib inflate buffer.
2. Request: Remove unnecessary read of PCI_CAP_ID_EXP The PCIE capability offset is saved during PCI bus walking. It will remove an unnecessary search in the PCI configuration space if this value is referenced instead of reacquiring it. Also, pci_is_pcie is a better way of determining if the device is PCIE or not (as it uses the same saved PCIE capability offset).
3. Request: CQ56790 - Pass the mf_mode to the CNIC so that CNIC can determine if it needs to call the DRV_CTL_START_NPAR_CMD/DRV_CTL_STOP_NPAR_CMD to setup the NIG when in NPAR mode.

Change: Enable the configuration for every port.
Relevance: DCBX, 578xx 4-port devices.
2. Problem: Warning message: "MDC/MDIO access timeout" on the first driver load. This warning appears during the link reset sequence, but it has no significant meaning, since it occur prior to the first phy initialization command.
Change: Adjust AER and CL45 clock during link reset sequence.
Introduced: Day one.
Relevance: 57712+8727.
3. Problem: "Soft lockup" errors. Caused by race between bnx2x_sp_task() and local IRQ both calling for napi_schedule(), which adds elements to a local NAPI list.
Change: Disable local IRQs when calling for napi_schedule() from bnx2x_sp_task().
Introduced: 1.60.17.
Relevance: FCoE only.
4. Problem: (CQ56741, CQ56744, CQ56697, CQ56590) "Soft lockup". Caused by race between dcb negotiation update flow and nic unload flow. The dcb update flow, which is an element in the sp work queue waits for rtnl lock in order to call bnx2x_setup_tc while nic unload flow which takes the rtnl lock waits for the sp work queue to be flushed.
Change: The dcb negotiation update flow now schedules the call to the bnx2x_setup_tc on the rtnl_sp task.
5. Problem: Possible problems in using fcoe and iscsi concurrently. The same cid was assigned to both.
Change: Allocate each its own cid.
Introduced: 1.70.15.

Introduced: 1.70.15.
Relevance: ESX only.
2. Problem: CQ56438 - Tx timeout was hit when there was a parity error and offloaded drivers (bnx2i/bnx2fc) loaded. It takes too long for the offloaded drivers to close (CNIC_STOP) bnx2x disabled a carrier after the CNIC_STOP completed.
Change: Moved the bnx2x_tx_disable() call to be before the CNIC_STOP call.
Introduced: Day one.
3. Problem: When DAC (Direct Attached Cable) is used, there's not actual link down event on the far side since transmitter output is not disabled.
Change: Disable transmitter output when link is disabled. The same change in MFW (since v7.0.20) will cause link to stay down using earlier version of this software (CQ56652). This version and after fixes it.
Introduced: Day one.
Relevance: 57712+8727.
4. Problem: CQ53144 - Repeating "NOHZ: local_softirq_pending 08" messages in the syslog: NAPI softirq was scheduled on a local CPU but ksoftirqd wasn't invoked. This was caused by calling the napi_schedule() for the FCoE L2 ring from a workqueue and not from the ISR as it is supposed to, which caused the above phenomenon.
Change: Disable local softirqs before napi_schedule() call (local_bh_disable()) and then re-enable them (local_bh_enable()). This will invoke the ksoftirqd if needed.
Introduced: 1.60.17.
Relevance: FCoE only.
5. Problem: In MF mode, when DCBX enabled, ifconfig down of PMF function may cause stop traffic on other function.
Change: Use generic scheme when configuring HW and FW for DCBX; Protect function from going down during inappropriate state.

6. Problem: CQ56292 - bnx2x assert dump when setting MTU to 9000. This was caused by an improper initialization of the fp->rx_buf_size for none-FCoE rings which led to improper initialization of BD buffer sizes for those rings.
Change: Fix the code that initializes the fp->rx_buf_size value.
Introduced: 1.70.08.
Relevance: FCoE on ESX only (CNA).
7. Problem: CQ56531 - Kernel crash due to page fault. Num of queues supplied to kernel erroneously included the iscsi queues which resulted with kernel choosing a transmission queue index beyond the boundary of the bxn2x's tx queues array.
Change: Supply the kernel with correct number of tx queues.
Introduced: 1.70.15.
Relevance: iSCSI OOO (since kernels 2.6.34 or Red Hat 6.0).

Change: (FW ETH) Fixed the flow in NIV mode to change a zero inner vlan vid to the NIV default vlan.
Introduced: 1.70.15 (FW 7.0.21).
Relevance: BCM57712/BCM578xx, only with NIV on packets with inner vlan.
13. Problem: CQ55328 - FCoE discovery does not work with ESX CNA device. The ESX stack would complain about the number of filters for the CNA NetQueue.
Change: Call netif_set_poll_cna() after the FCoE NAPI structure has been initialized.
Introduced: 1.70.08.
Relevance: ESX CNA only.
Enhancements ------------ 1. Request: Optimized the memory barriers usage in the slow path.

Change: (FW) Remove wrong clock initialization from init tool and move it to MCP.
Introduced: Version 1.70.13 (FW 7.0.20).
Relevance: BCM57800. Power-cycle of the device is needed in order to fix the Storm frequency, a regular driver update is not enough.
9. Problem: Possible race between writing event-ring element and updating the host-coalescing index.
Change: (FW) Fix the flow by sending host-coalescing index update only after the completion of the event-ring writing.
Introduced: Version 1.70.01 (FW 7.0.0).
10. Problem: Basic FCoE on NPAR-SD was not working.
Change: (FW-FCoE) Fixed the flow in NPAR-SD mode to add default vlan also when there is vlan with vid=0 on packet.
Relevance: BCM57712 and BCM578xx, only NPAR-SD mode.
Enhancements ------------ 1. Request: Propagate WWN info up to bnx2fc driver.

Version 1.70.14 (Jun 14, 2011) ============================== Internal FW: 7.0.20
Fixes: ------ 1. Problem: Possible spurious cnic interrupt.
Change: Properly disable cnic sb.
Introduced: 1.60.00.
Relevance: (Theoretical) when CNIC is supported.
2. Problem: In NPAR-SD mode, VIF SET request for FCoE function takes more than 40 seconds to be completed and ACKed back to the MCP.
Change: Queue update ramrod sent to FCoE ring couldn't wait for completion in the same context. Therefore, don't wait for completion for this ramrod on FCoE ring.
Introduced: 1.70.00.
Relevance: FCoE in NPAR-SD mode.
3. Problem: In NPAR-SD mode, theoretically traffic can be dropped due to early VIF SET ACK sent back to the switch.
Change: Send VIF SET ACK from driver to MCP only after function update ramrod is completed + all queue updates ramrods are completed.
Introduced: 1.70.10 (when silent vlan removal was added).
Relevance: NPAR-SD mode.
Enhancements ------------ 1. Request: CQ53961 - Remove 10Mbps from 84833 PHY. Honor PHY speed attributes for 10/100. If the driver is set up to advertise only 10M, no speed capability will be advertised. And no link will be established.
Relevance: 84833 PHY based boards.
2. Request: Add definition for autogreen in eLink.
Relevance: 84833 PHY and 54618SE PHY based boards.
Version 1.70.13 (Jun 12, 2011) ============================== Internal FW: 7.0.20
Fixes: ------ 1. Problem: Driver might set NPAR-SD mf_mode even if that mode can't be set. Driver sets NPAR-SD according to value written to NVRAM, without considering error cases such as missing NVRAM images etc.
Change: Set mf_mode to NPAR-SD only if mac address in shmem is valid. If address in shmem is valid, then MFW performed all checks and found that mode as valid.
Introduced: Day one.
Relevance: NPAR-SD mode only.
2. Problem: Memory leak in during selftest. Driver mapped skb twice.
Change: Do it once.
Introduced: 1.70.09.
3. Problem: CQ55933 - ESX CNA enabled driver tries to configure Rx mode for an FCoE ETH queue for NICs that do not support an FCoE.
Change: Configure Rx mode for an FCoE ETH queue only for the NICs that support FCoE (57712 and newer).
4. Request: Added support for 2 queues on different CoSes in 57712 and 578xx A0.
5. Request: Performance improvements in order to resolve PCI bottleneck on short packet PPS test on multiple connections.
Version 1.70.12 (May 24, 2011) ============================== Fixes ----- 1. Problem: (CQ55655) WOL is not functional on functions 2-7.
Cause: Incorrect register configuration.
Change: Allow WOL via HW registers.
Impact: Introduced in 1.64.01.
2. Problem: Undefined device behaviour when bringing up more than 16 eth queues with CNIC enabled.
Cause: Resource management mechanism does not allow more than 16 queues without actual limiting the number.
Change: Limit number of eth queues to 16.
Impact: 57712 only.
3. Problem: Possible no link on 578xx SFP+.
Cause: Failed reading from SFP+ module EEPROM due to I2C register not returning acknowledge over successful operation.
Change: Add work-around of up to 3 retries in case of I2C failure.
Impact: 578xx SFI.
4. Problem: (CQ55748) Link loss during up/down test.
Cause: Race in driver code causes it to get out of sync.
Change: Fix assignment with the lock.
5. Problem: In NPAR-SD mode, iSCSI and FCoE MAC addresses for relevant functions are zero.
Cause: In NPAR-SD mode, iSCSI and FCoE MAC addresses were not taken from shmem for functions in which these protocols are enabled.
Change: If NPAR-SD mode is used and the function is iSCSI/FCoE enabled, read suitable MAC addresses from shmem.
6. Problem: In NPAR-SD mode, default vlan tag might not be silently removed by the FW.
Cause: default vlan value and mask sent to FW in function update ramrod (for NPAR-SD mode) includes 3 bits of priority.
Change: default vlan value and mask in function update ramrod will include only 12 bits of vlan id.
7. Problem: Parity recovery was broken.
Cause: Improper handling of starting and termination of the 'periodic_task'.
Change: Ensure that only a PMF is running a periodic task. Stop a periodic task when a function is shut down.
Impact: Introduced in 1.70.09.
8. Problem: Chip may crush under PF FLR.
Cause: Driver could get interrupt on a disabled function.
Change: (In FW 7.0.18) Fixed relevant firmware flow.
Impact: Introduced in 1.70.00 (FW 7.0.0)
9. Problem: Improper device behaviour on BE platform.
Cause: Use improper calculation for FW offsets.
Change: Use FW offsets instead.
Impact: Introduced in 1.64.01
Enhancements ------------ 1. Request: Add the ability to switch settings from one speed to another in the Warpcore without having to unload the driver.
Change: Add a routine to restore the Warpcore register settings back to default. The routine is called before configuring the Warpcore to the desired speed settings.
Impact: 578xx only.
2. Request: Separate the accounting of the context-less SP commands and those that complete on the FP Rx ring.
Change: As requested.
3. Request: Reduce loading time when not in hotplug flow.
Change: As requested.

6. Request: (CQ55781) Allow GDB script to poke at the hardware registers.
Change: As requested.
Impact: ESX only.
7. Request: Reduce number of pcie transactions in high PPS rate scenarios.
Change: (In FW 7.0.18) Changing Status block DMA to host to be read from RAM instead of 3 IMM DMA's. This reduces the number of transactions on PCI and resolves with faster replenishment of PCI credits, since we reduced the number of read modify write transaction on host cash lines.
8. Request: Use FW 7.0.18.
Change: As requested.
Version 1.70.11 (May 18, 2011) ============================== Fixes ----- 1. Problem: (CQ55251) "BAD MCP validity signature" shown when device hot-plugged.
Cause: Race between FW initialization and driver load.
Change: Let FW to complete initialization by adding msleep in driver.
2. Problem: TPA is not functional on platforms where CONFIG_NEED_DMA_MAP_STATE is not defined.
Cause: We used dma_unmap_addr_set() and dma_unmap_addr() macros for internal storing and for further retrieving of the DMA mappings which were then used for BDs configuration in the TPA Rx flow while dma_unmap_addr() will always return zero on the mentioned above platforms.
Change: Don't use the mentioned above macros in flows others than "map->unmap".
Impact: TPA only. Introduced in 1.70.09.
3. Problem: Compilation failed on SLES11 SP1 update 1.
Cause: Conflict on backported feature.
Change: Fix bnx2x_compat.h.
Impact: SLES11 SP1 update 1 only.
4. Problem: Wrong link LED when speed lower than 10G on 578xx devices.
Cause: Incorrect LED mode setting.
Change: Set correct LED mode setting.
Impact: 578xx devices only.
5. Problem: One queue is not selected for transmission in kernels below 2.6.38.
Cause: Incorrect mapping function.
Change: Fix compat to implement mapping similar to 2.6.38.
Impact: Kernels below 2.6.38 with multi queue support.
6. Problem: TCM, DMAE, PBF, TIMERS, XCM, DMAE parity errors were ignored, while still asserting the "close the gates" bit.
Cause: The appropriate bits were not checked when checking for parity errors.
Change: Added the missing bits handling to the parity recovery code.
7. Problem: Compilation failed on RHEL 5.7.
Cause: Conflict on backported feature.
Change: Fix in bnx2x_compat.h.
8. Problem: (CQ55312) DMAE timeout message shown in the syslog when loading the first function on the port.
Cause: BMAC was reset after the NIG-to-BRB channel was open and before the FW was initialized. This caused the parity error in TCM.
Change: Reset BMAC before opening NIG-to-BRB channel.
Impact: Introduced in 1.70.04.
Enhancements ------------ 1. Request: Optimize buffer mapping manipulations in the TPA flow.
Change: As requested.
2. Request: Don't use atomic bit operations unless needed.
Change: As requested.
3. Request: Propagate the CFC_DEL ramrod error code up to CNIC.
Change: As requested.
Version 1.70.10 (May 5, 2011) ============================== Fixes ----- 1. Problem: LRO failure in IPv6 case.
Cause: Erroneous calculation of lro_mss size for IPv6 case.
Change: Fix LRO MSS calculation in IPv6 case.
Impact: 57712 and newer IPv6 LRO only.
2. Request: Potential link issue.
Cause: Incorrect code alignment led to bad PHY struct initialization.
Change: Fix PHY struct initialization.
Impact: Introduced on 1.70.09.
3. Request: Potential inconsistent link state report towards OS.
Cause: Possible race between netdev->open() and link attention handling flows both reporting link state towards OS.
Change: Protect the link reporting code with the same locking scheme as used for the link state handling protection.
Enhancements ------------ 1. Request: Use FW 7.0.17.
Change: As requested.
2. Request: Employ silent vlan removal feature.
Change: Silent vlan removal use: 1. In NPAR-SD mode silently remove the default vlan. 2. In ESX Network Plug-in Architecture silently remove the NPA default vlan. 3. When DCB is enabled in kernels which don't treat vlan-0 as non-vlan use silent vlan removal to: a. Remove vlan 0 with priority 0 if non fcoe queue. b. Remove vlan 0 with any priority if fcoe queue.
3. Request: Do not add VLAN tag or modify the priority of an explicit vlan tag of packets with TC_PRIO_CONTROL value in the skb priority.
Change: As requested.
Version 1.70.09 (May 3, 2011) ============================== Fixes ----- 1. Problem: (CQ53629) System spontaneously reboots.
Cause: PCI/DMA address mapping error not properly handled by driver, which may cause chip to access improper addresses in host memory.
Change: Add proper handling for mapping errors.
2. Request: (CQ49132) Link seen as up when cable(mostly fiber) is not fully connected.
Cause : In this scenario, the physical link is up, while error are detected on the MAC layer.
Change: Add periodic check for LSS errors on the MAC layer, since they don't provide indication by interrupt.
Impact: Currently only 57712. Note that this fix will not discover a case where one of two wires of fiber cable is plugged out.
3. Problem: Storms get stuck shortly after a single-engine recovery.
Cause: Functions were not unloading against MCP in case of parity error thus later LOAD request was always returning a FUNCTION load code. This lead to improper HW/FW initialization.
Change: Added unloading against the MCP in case of parity error.
Impact: 57712 and newer only. Introduced in 1.70.06.
4. Problem: Kernel panic when handling egress UDP packet for which checksum offload has been requested.
Cause: The above case hasn't been properly handled in the code.
Change: Add a proper handling for the above case.
5. Problem: In case of VLAN removal of a first small packet in TPA aggregation, driver may access uninitialized address.
Cause: Firmware places a corrupted RX completion element in this case.
Change: (in FW 7.0.16) Fixed relevant firmware flow.
Change: (in FW 7.0.16) Fixed relevant firmware flow.
Impact: Introduced in 1.70.01 (FW 6.4.0). 578XX 4-port only.
8. Problem: (CQ53924) Ethtool Self Test fails loopback test.
Cause: Unmapping of dma memory was not performed before accessing it.
Change: Added unmap of the relevant memory.
9. Problem: MDC/MDIO access to Warpcore registers may fail with low probability.
Cause: Warpcore PCB controller may get stuck without having MDC free running in the system.
Change: Add work-around for 578xx-A0 by adding another write to the MDIO bus after each MDC access to the Warpcore. This will be fixed in HW for 578xx-B0.
Impact: 578xx.
10. Problem: (DCB)(CQ54899) PMF migration may cause DCB get out-of-sync.
Cause: Driver did not update port structure correctly.
Change: Fixed DCB update code.
Impact: Introduced in 1.70.06.
11. Problem: The following error is logged as soon as bnx2fcd service is started: "kernel: 8021q: device eth# has buggy VLAN hw accel".
Cause: Under Red Hat 6.1 the bnx2x was compiled assuming the netdev centralized handling of hardware acceleration exists in kernel.
Change: Changed the bnx2x to compile using the old scheme of handling of hardware acceleration in RH6.1.
Impact: RH6.1
12. Problem: (CQ53276) 578xx ethtool display and settings are not done per board type.
Cause: Missing distinctions between various Warpcore interfaces.
Change: Check Warpcore network interface during init stage, and update the supported network attributes accordingly.
Impact: 578xx
13. Problem: (CQ54552) System breaks once link is up after PMF migration when speed is 1G.
Cause: Missing synchronization flag between PMF and non-PMF which indicate the XGXS type, led to incorrect initialization once link is up after PMF migration.
Change: Initialize this flag during synchronization
14. Problem: ethtool will not show the correct media type after PMF migration and changing the SFP+ module type
Cause: Media type was not synchronized after it is changed
Change: Synchronize media type between PMF and non-PMF
Impact: SFP+ based boards. Introduce on 1.64.19
15. Problem: Over-current message displays with port0 instead of port1 on 57712 SFP+ devices.
Cause: 57712 port enumeration is per path.
Change: Set the correct port number of the over-current display message according to the device type.
Impact: 57712 with SFP+ boards.
16. Problem: Possible dead locks in slow path flows involving interface toggling.
Cause: vlan_mac object was using spin_lock() semantics instead of spin_lock_bh() semantics while it may be called under a spin lock with BHs disabled in the ndo_set_rx_mode() flow.
Change: Fixed the mentioned above code.
Impact: Introduced in 1.70.06.
17. Problem: A possible deadlock in flows involving the DMAE operations.
Cause: We protected the DMAE engine with mutex (suspends a task when lock can't be taken) in the bnx2x_issue_dmae_with_comp() function while it is also called under a spinlock in the ndo_set_rx_mode() flow.
Change: Protect the above DMAE engine with a spinlock instead of a mutex.
Impact: Introduced in 1.70.06. 57712 and newer in the NPAR mode only.
Enhancements ------------ 1. Request: Add preliminary support for E3+84833 to pass extlb_test. Caveat that both drivers must be loaded at this time to function correctly.

Impact: 578xx.
5. Request: Use FW 7.0.16.
Change: As requested.
6. Request: Write driver version string to specified offset in scratchpad for NC-SI OEM commands.
Change: Read scratchpad offset from ncsi_oem_data_addr field of shmem2. Then, write driver version to appropriate offset.
7. Request: Remove zeroing of Ram0 from driver as it is performed by init tool.
Change: Removed relevant code and the defines.
Version 1.70.08 (Apr 11, 2011) ============================== Fixes ----- 1. Problem: Possible chip hang in case of parity error in QM.
Cause: QM was reset before PXP causing 'close the gates' to be de-activated shortly before resetting PXP, PSWRQ sends a write request to PGLUE, PXP is reset, PGLUE tries to read the payload data from PSWWR, but PSWWR does not respond. The write queue in PGLUE will be stuck, DMAE commands will not return.
Change: Change reset order of PXP and QM blocks so that PXP is reset before QM.
Impact: During error recovery flow of QM parity attention only. Introduced in 1.53.1.
2. Problem: Tx of a CNA netdev wasn't properly disabled.
Cause: Typo in a bnx2x_tx_disable().
Change: Fix the above typo.
Impact: ESX CNA only. Introduced in 1.64.13.
3. Problem: Fairness issue between functions 0, 1 and functions 2,3 on 57840 4x10G.
Change: Do not overwrites cnic_eth_dev->drv_state in bnx2x_register_cnic().
Impact: iSCSI and FCoE only.
5. Problem: Possible inconsistent rx_mode state for iSCSI L2 queue.
Cause: Both BNX2X_FILTER_ISCSI_ETH_START_SCHED and BNX2X_FILTER_ISCSI_ETH_STOP_SCHED bits might be set, which in line might cause the situation when the rx_mode that is finally configured is not the one that has been requested the last.
Change: Clear the already pending state when configuring the new one.
Impact: iSCSI L2 only.
6. Problem: (CQ51066) Link status in port mailbox indicates AUTONEG is disabled and no Serdes.
Cause: Link status was zeroed during link down state.
Change: Set AUTONEG and SERDES indications when needed.
7. Problem: Possible pending SP ramrod completion after FUNC_STOP ramrod is sent.
Cause: Missing protection when checking bits in bnx2x_wait_sp_comp().
Change: Added the protection with netif_addr_lock for the mentioned check.
Impact: Introduced in 1.64.00.
8. Problem: (CQ54422) Compilation Failed on RHEL 6.1.
Cause: Backported features complict.
Change: Adopt features in compat.
9. Problem: Potentioal race in NPAR-SD mode might cause sending of function update ramrod before function start ramrod is completed.
Cause: LOAD_DONE message to MCP is sent before function start ramrod. LOAD_DONE request starts VIF initialization process that ends with VIF_SET request from the switch that triggers function update ramrod.
Change: Perform function start ramrod before sending LOAD_DONE message to MCP.
2. Request: Integrate the upstream "Support for managing RX indirection table" patch by Tom Herbert implementing the support for ethtool -X/-x options.
Change: Integrated the mentioned patch taking into the account all remarks of the netdev people about this patch.
3. Request: Add 1G support for XFI serdes network interface type of Warpcore
Change: As requested

Cause: Incorrect GPIO assignment.
Change: Fix GPIO setting that controls the TX fault LED.
Impact: 578xx - SFP+.
2. Problem: DAC may not link up.
Cause: Register read was missing after setting EDC mode.
Change: Read EDC register after setting it.
Impact: 578xx - DAC.
3. Problem: Parity errors prevent device from load on emulation environment.
Cause: Emulation environment limitation.
Change: Disable parity on emulation environment.
Impact: Emulation environment only.
4. Problem: Incorrect SFP+ module power setting.
Cause: Value was swapped.
Change: Reverse value to fit board scheme.
Impact: 578xx SFP+ when nvm cfg #160 is set.
5. Problem: When accept all TX packets is enabled (all TX packets are duplicated to both the physical and loopback ports), LSO traffic throughput is less than expected.
Cause: Firmware accounted duplicated LSO (and also some non-LSO) packets twice in the rate shaping algorithm, instead of only once.
Change: (In FW 7.0.15) Fixed relevant firmware rate shaping bytes calculation for duplicated TX packets.
Impact: Introduced in 1.64.01 (FW 6.4.0).
6. Problem: PF FLR while VFs are running may cause system to get stuck.
Cause: If VF FLR happens after PF is down, the VF may try to send an event message to the PF by mistake.
Change: (In FW 7.0.15) Fixed relevant firmware flow.
Impact: Introduced in 1.70.00 (FW 7.0.0).
7. Problem: When TPA is enable, tcp packets with erroneous length might add wrong bytes to packet.
Cause: Firmware didn't verify the packet length is equal Ethernet header + IP total length.
Change: (In FW 7.0.15) Added the required verification.
Impact: Introduced in 1.64.01 (FW 6.4.0).
8. Problem: (FCoE) FCoE on physical port 1 can't be enabled.
Cause: Wrong cos allocation.
Change: (In FW 7.0.15) Fixed relevant firmware flow.
Impact: 57810/57840 only. Introduced in 1.70.00 (FW 7.0.0).
9. Problem: (iSCSI) Chip hangs upon arrival of iSCSI packet with split digest.
Change: Add DCBX notification mechanism during PMF migration.
3. Problem: (DCB) Static configuration is not properly handled.
Cause: Static configuration flow does not handle HW interrupt, because of state where DCBX initialization performed.
Change: Move DCBX initialization to the end of nic_load.
Impact: DCBX involved flows.
4. Problem: (CQ53768) Kernel panic at bnx2x_cnic_reuse_ooo_pkt.
Cause: Wrong arithmetics on Tx HW consumer for a Forwarding ring.
Change: Fixed the above arithmetics.
Impact: iSCSI OOO only. Introduced in 1.64.00.
5. Problem: (CQ53347) Data does not validate reported while running Chariot for RH6.0 x64.
Cause: In case of VLAN removal of a first packet in TPA aggregation, firmware may add padding bytes in the middle of the packet.
Change: (in FW 7.0.14) Fixed relevant firmware flow.
Impact: Introduced in 1.70.00.
6. Problem: (CQ53523) System stuck during load/unload under traffic.
Cause: RX processor can get stuck in infinite loop when a set mac configuration is done during traffic.
Change: (in FW 7.0.14) Fixed relevant firmware flow.
Impact: Introduced in 1.70.00.
7. Problem: Link may not come up after SFP+ module plug in on BCM8726 based boards
Cause: Module detection was not triggered by module insertion, which may lead to incorrect setting of EDC mode
Change: Initialize AEU before collecting the group of signals in charge for generating interrupts
Impact: BCM8726 based boards Introduced in 1.52.50
8. Problem: (CQ54040) Unable to perform iSCSI login.
Cause: Missing iSCSI L2 and Netq MAC ramrods completion handling.
Change: Added a missing code.
Impact: iSCSI and ESX only.
9. Problem: bnx2x_func_state_change() and bnx2x_queue_state_change return a negative value while PENDING (1) value should be returned.
Cause: test_bit(nr, vec) returns all-F's if nr is a variable and the requested bit is set.
Change: Chaged test_bit(nr, vec) to !!test_bit(nr, vec) when nr is a variable.
Impact: Introduced in 1.64.08.
10. Problem: If MCP sends to driver second NPAR-SD event before first one handling is done, no NPAR-SD events will be handled since now on. Note that second event from MCP while first one is not done yet should not happen due to "one pending" mode, but it is good practice to handle both messages if such a scenario occures in some way.
Cause: drv_status field was checked to match exact value instead of bit masking the value to match various events.
Change: Check drv_status bits to know which NPAR-SD events should be handled.
Impact: NPAR-SD mode only.
11. Problem: (CQ52000 & CQ51697 Cont.) XAUI short detection mechanism only applies to 10G.
5. Request: Add a support for a parity errors recovery for 57712 and newer.
Change: As requested.
6. Request: Add MOD_ABS support for 578xx SFP+ modules
Change: As requested.
7. Request: Invert OPTRXLOS signal on SFP/XFP interface for 578xx
Change: As requested.
Version 1.70.05 (Mar 17, 2011) ============================== ***** This version does not support CNIC *****
1. 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.
2. 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: Introduced in 1.64.09.
3. Problem: (CQ52834) (iSCSI) connection/login issues in DCBX environment.
Cause: Erroneous context override by firmware.
Change: (in FW 7.0.12) Fixed relevant firmware flow.
Impact: DCBX environment only.
4. Problem: (CQ53526) (NPAR) Driver asserts while running iSCSI/L2 traffic.
Cause: Forward channel configured for TX switching.
Change: Disable TX switching for FWD channel.
Impact: NPAR mode.
5. 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.
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: No fan failure notification when the fan failed and nvram option 83 is set to enabled.
Cause: The fan failure worked only for specific external PHYs and not according to option 83.
Change: Enable fan failure regardless of the PHY type if option 83 is set to enable.
Impact: No fan failure notification unless the PHY is SFX7101, BCM8073, BCM8481, BCM84823 or BCM84833 - other PHYs or designs without external PHY will not report fan failures (but the FW will stop the PHY).
8. Problem: Ethtool self test idle check tests erroneously for active connections.
Cause: 1. Input registers were confused. 2. Connection type bit offset has changed since 57712.
Change: Converted self test idle check to work with static record array Corrected register confusion and location of connection type.
Impact: Saved 18% off linux driver compilation time.
9. 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.
10. Problem: (CQ52887) Interrupt test using ethtool's self test fails.
Cause: The ramrod, RAMROD_CMD_ID_ETH_EMPTY, is used for both the interrupt test and NetQueue commands. When self test is ran, the NetQueue would always intercept this ramrod but not complete the command.
Change: Do not explicitly intercept the EMPTY ramrod in the netq code. Instead use the appropriate SP queue object to send the EMPTY ramrod.
Impact: ESX only.
11. Problem: ethtool shows the wrong port connected.
Cause: Dual media port presentation was swapped.
Change: Show the active port.
Impact: Dual media board.
12. Problem: (CQ53303, CQ52600) Firmware doesn't support FLR on both ports on the same path simultaneously on 578xx.
Cause: The Flr flow hold some variables only for the last port treated.
Change: (in FW 7.0.13) Added an array to hold separate variables for each port.
Impact: Only 578xx.
13. Problem: FCoE doesn't identify function in NPAR-SD mode.
Cause: FW use MAC classification.
Change: (in FW 7.0.13) Classify function according to ID.
Impact: Introduced in 1.70.01.
14. Problem: (iSCSI) Chip hangs upon arrival of iSCSI packet with FIN flag set.
Cause: Tstorm signals Ustorm to release same BRB block twice.
Change: (in FW 7.0.13) Fixed relevant firmware flow.
Impact: Introduced in 1.64.01.
Enhancements ------------ 1. Request: Add initial support for 1G over fiber.
Change: As requested.
Impact: 578xx fiber.
2. Request: (CQ50798) Add support for BCM8722.
Change: As requested.

Change: As requested.
7. Request: Honor GPIO configuration values on Tx laser control, on top of existing EPIOs.
Change: As requested.
Impact: 578x0 SFP+ designs.
8. Request: Link support for Everest 57810 + 84833B0PHY.
Change: As requested.
Impact: Everest 57810 + 84833B0PHY combination can pass traffic for testing.
9. Request: Add SGMII support for a specific OEM design.
Change: Clear signal detect and configure internal PHY before BCM54618SE establishes link.
Impact: SGMII ports of 57800 only.
10. Request: (CQ52000 & CQ51697) Short on XAUI lanes on the MAC side of 8727 and 8706 PHYs 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 and 8706 PHYs.
11. Request: Support added for E3 + 84833B0 PHY firmware upgrade.
Change: As requested.
Impact: E3 + 84833B0 PHY combinations.
12. Request: Disable Tx switching for 57712/578xx.
Change: As requested.
Impact: 57712/578xx in NPAR mode, ESX.
Version 1.70.04 (Mar 01, 2011) ============================== ***** This version does not support CNIC ***** Fixes ----- 1. Problem: (CQ53258) Ethtool self test fails loopback_test (offline) when run on the copper ports
Cause: Test was done over 10G rather than 1G, and test did not wait long enough for the link to come up
Change: When speed capability doesn't include 10G, then perform the self test using 1G. In addition, for PHY loopback test, wait for the link to come and not assuming it is already up.
Impact: 57800 copper ports
2. 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 1.70.03 (Feb 24, 2011) ============================== Fixes ----- 1. Problem: ethtool -t under heavy traffic may show idle_check error.
Cause: idle_check mistakenly reported error.
Change: Fix idle_check routine.
2. Problem: (CQ53143) Configuring a primary ETH MAC with ifconfig tool didn't clear the old MAC configuration.
Cause: Missing code that clears the old MAC configuration.
Change: Added a missing code.
Impact: Introduced in 1.64.00.
3. Problem: (CQ51593) Statistics are inaccurate on 578xx devices.
Cause: Improper handling data from MSTAT HW block.
Change: Fix data handling.
Impact: 578xx only.
4. Problem: "DMAE timeout" appears in syslog and chip halts.
Cause: Improper HW initialization sequence.
Change: (v2) Fixed relevant init sequence.
Impact: Introduced in 1.70.00.
Enhancements ------------ 1. Request: Translate 10G-Force KR and 1G-Force KR to autoneg with advertisement of 10G and 1G in accordance.
Change: As requested.
Impact: 578xx KR interface.
2. Request: Support NVRAM configuration of EPIO assignment on Tx laser control.
Change: As requested.
Impact: 578xx SFP+ interface, existing boards with this parameter unconfigured should still work using hardcoded default EPIO.
Version 1.70.02 (Feb 21, 2011) ============================== Fixes ----- 1. Problem: (CQ52452, CQ50960) VLAN stripping is not enabled for higher functions when function 0 is not up.
Cause: Function ID field was always set to zero in UPDATE ramrod data.
Change: Properly configure the above field in the ramrod data.
Impact: Multi-function only. Introduced in 1.64.00.
2. Problem: NULL pointer dereference in a flow of closing iSCSI L2 queue.
Cause: SW bug that caused cnic handler routine not to be called for CFC_DEL ramrod completion of iSCSI L2 queue.
Change: Fix the above SW bug.
Impact: iSCSI only. Introduced in 1.70.01.
3. Problem: (CQ52417), (CQ52845) Flow control doesn't work for 20G.
Cause: Flow control wasn't enabled for 20G.
Change: Set flow control on 20G according to settings.
Impact: 57840 20G.
4. Problem: (CQ52023) Driver asserts with HW attention.
Cause: Traffic type to priority/COS table was reset after link down by driver causing transmission on the wrong COS.
Change: (In FW 7.0.10) Removing the table in RAM from HSI section.
Impact: Introduced in 1.64.00 (FW 6.4.0).
5. Problem: System may crash when configuring some RX rings with TPA enabled and some with TPA disabled.
Cause: Firmware tries to do TPA also for the non-TPA clients.
Change: (In FW 7.0.10) Fixed relevant firmware flow.
Impact: Introduced in 1.64.9 (FW 6.4.15). BCM57710/57711/57711E only.
6. Problem: System crash under TCP traffic when driver is toggling TPA.
Cause: Firmware bug.
Change: (In FW 7.0.10) Fixed relevant firmware flow.
Impact: Introduced in 1.64.03 (FW 6.4.7).
7. Problem: Firmware aggregated packets with wrong checksum.
Cause: Firmware didn't check checksum as a requirement for aggregation.
Change: (In FW 7.0.10) Fixed relevant firmware flow.
Impact: Introduced in 1.64.0 (FW 6.4.0).
8. Problem: 10G-KR doesn't link up on an OEM design.
Cause: CL72 should not be disabled in KR environment.
Change: Removed codes that disables CL72.
Impact: 578xx 10G-KR.
9. 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.
10. Problem: System locks up after loading driver on 1Gb copper ports.
Cause: Incorrect interrupt acknowledge when link change occurs lead to interrupt storm.
Change: Acknowledge the interrupt correctly on 1G ports.
Impact: 578xx with 2x1G and 2x10 port. Introduced in 1.70.01.
11. Problem: When resetting/disabling link in 578xx boards output for TX PAUSE signal to the MAC is not disabled
Cause: Relevant register in the NIG is not cleared when link is disabled.
Change: Set value to 0 in that register if link is disabled.
Impact: 578xx.
12. Problem: BCM578xx may misconfigure the link on some OEM designs.
Cause: ELink determines 4-port mode strictly from the input pin, not from override register that MFW always configures.
Change: Changed to determine the 4-port mode by reading the override register.
Impact: 578xx.
13. Problem: Driver unload may halt under traffic fails.
Cause: Incorrect order of disabling XMAC.
Change: Close the XMAC RX path before issuing XMAC soft reset.
Impact: 578xx.
14. Problem: (CQ51417) ethtool -t may cause device to hang.
Cause: Race in interrupt handling during self test.
Change: Wait for SP completions in load flow to avoid the race.
Impact: Introduced in 1.64.01.
15. Problem: Drivers assert while transmitting packets.
Cause: Firmware lose packets synchronization during transmission (Xstorm Assert).
Change: (In FW 7.0.11) Fixed relevant firmware flow.
Impact: Introduced in 1.64.10. (FW 6.4.15). 57712/578xx only.
16. 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 7.0.11) Fixed relevant firmware flow.
Impact: Exists in all previous versions. 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.
17. Problem: "DMAE timeout" appears in syslog and chip halts.
Cause: Improper HW initialization sequence.
Change: Fixed relevant init sequence.
Impact: Introduced in 1.70.00.
18. Problem: ethtool -t fails on 578xx B0.
Cause: test accessed unexistent registers.
Change: remove improper access.
Impact: 578xx only.
Enhancements ------------ 1. Request: Remove support for 57710 emulation and FPGA.
Change: As requested.
2. Request: Add performance improvements to Ethernet TX flows in BCM57711.
Change: (In FW 7.0.10) Added optimizations in TX flow.
3. Request: Use FW 7.0.11.
Change: As requested.
4. Request: CQ52000 Short on XAUI lines between Everest 2 and 8727 PHY needs to generate link down event.
Change: Tx fault detection has been added. In addition link qualification includes checking for Tx fault.
5. Request: Collect FW TPA statistics: aggregations, bytes in aggregations and a number of aggregated network frames.
Change: As requested.
Version 1.70.01 (Feb 07, 2011) ============================== Fixes ----- 1. 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 probe stage, instead of the common and port init stage.
Impact: Multi-function 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: 8073PHY 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: L2 TX LSO Packets with LLC-SNAP header and in-band VLAN header are corrupted (BCM57710/BCM57711/BCM57711E).
Cause: Firmware sends an illegal command, resulting with a corrupted header in such cases.
Change: (in FW 7.0.9) Fixed relevant firmware flow.
Impact: BCM57710, BCM57711 and BCM57711E only.
5. Problem: (iSCSI) Chip hangs when running iSCSI IOs bigger than 32KBs.
Cause: Firmware bug.
Change: (in FW 7.0.9) Fixed relevant firmware flow.
Impact: Introduced in 1.64.01 (FW 6.4.0).
6. Problem: 57710 constantly get a parity errors in PBF and TM blocks during TCP/UDP traffic.
Cause: False parity errors in the above blocks. PBF and TM blocks parity error attentions are not implemented in 57710.
Change: Don't enable parity attentions in the PBF and TM blocks on 57710.
Impact: 57710 only. Introduced in 1.70.00.04.
7. Problem: The atempt to configure iSCSI MAC address would cause a "NULL pointer dereference" error when CNIC module was loaded before L2 interface is opened.
Cause: iSCSI L2 MAC object was initialized before bp->slowpath memory was allocated (bp->slowpath was NULL at that stage). So, as long as the object used references to bp->slowpath memory, it caused the above error, when we tried to utilize it.
Change: Move iSCSI L2 MAC object initialization from bnx2x_cnic_probe() to the DRV_CTL_START_L2_CMD callback.
Impact: iSCSI L2 only. Introduced in 1.64.00.
8. Problem: iSCSI L2 queue wasn't receiving any packet.
Cause: Rx mode of this queue didn't have ACCEPT_ANY_VLAN option. Therefore FW filtered every packet by VLAN (assuming untagged frames having VLAN_ID 0) and as long as there were no HW VLAN acceleration configured, no frames were delivered to iSCSI L2 queue.
Change: Added ACCEPT_ANY_VLAN option to iSCSI L2 queue rx mode.
Impact: iSCSI UIO only. Introduced in firmware version 1.64.00.
9. 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.
10. 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.
11. Problem: (CQ51417) Running ethtool -t causes the interface to hang.
Cause: Link test was checked according to 57711/2 scheme rather than 578xx.
Change: Test link according to the chip type.
Impact: BCM578xx.
12. Problem: Possible problems with buffers mapping in iSCSI OOO flow on kernels 2.6.34 and newer.
Cause: Improper mapping functions used (pci_xxx instead of dma_xxx).
Change: Use the proper mapping functions in the above flow.
Impact: iSCSI OOO only. Kernels 2.6.34 and newer. Introduced in 1.60.15.
Enhancements ------------ 1. Request: Add autoneg parallel detect and pause support for 578xx KR.
Change: As requested.
Impact: 578xx-KR.
2. Request: Use FW 7.0.9.
Change: As requested.
3. Request: Set default number of rx buffers to be divided equally between rx queues to decrease amount of pre-allocated buffers on systems with multiple CPUs.
Change: As requested.
4. Request: Configure a mini-jumbo (2500) MTU for FCoE L2 ring. Don't change it when NIC's MTU changes.
Change: As requested.
5. Request: Call for a cnic handler routine for CFC_DEL ramrod completion of iSCSI L2 queue.
Change: As requested.
Version 1.70.00.4 (Jan 19, 2011) ============================== Fixes ----- 1. Problem: VIF_LIST_GET request in NPAR-SD mode responded always with zero value.
Cause: drv mailbox param value was cleared after valid value was written, and therefore zero was read by the MCP and sent to the switch.
Change: Fix the logic.
Impact: NPAR-SD mode only.
2. Problem: Warpcore microcode wasn't loaded as image from nvram.
Cause: Non-clear loading sequence from the nvram forced loading microcode statically as temporary work-around.
Change: Warpcore microcode will be loaded solely from the nvram by the bootcode.
Impact: 578xx only; Requires bootcode 7.0.0.0/6.4.3 and above.
3. Problem: Statistics is not displayed correctly on 578xx.
Cause: Improper initialization.
Change: Fix initialization flow.
Impact: 578xx only.
4. Problem: NPAR-SD packets did not reach MCP after driver is loaded.
Cause: NIG registers initialization by the driver did not mark that NPAR-SD tag header can be included in rx packets, and overwrote value inserted by the MCP.
Change: Write correct value to that register in NPAR-SD mode.
Impact: NPAR-SD mode only.
5. Request: BCM8727 Link LED not functioning properly during BACS LED test.
Change: Not blinking correct link light.
Impact: BCM57712 + BCM8727 based boards.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. Problem: "Statistics sequence counter out of order" storm 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.
13. 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.
14. Problem: Kernel panic when loading bnx2x with int_mode=1 and disable_iscsi_ooo=1.
Cause: INT#x ISR was scheduling iSCSI OOO ring's NAPI regardless NO_ISCSI_OOO flag.
Change: Consider NO_ISCSI_OOO flag before scheduling iSCSI OOO ring's NAPI.
Impact: Introduced in 1.64.07.
15. Problem: XSTORM assert due to wrong values in XSTORM RAM, occurring after turning up first interface on the other path (specifically traffic_type_to_priority_cos table was cleared in XSTORM RAM).
Cause: driver used to reset LCPLL in bnx2x_init_hw_common process, which is performed per each path. That configuration is not needed as it is done by the MCP, and is wrong because LCPLL is common and not per path.
Change: Remove that configuration from driver (it is done by MCP).
16. Problem: In NPAR-SD mode - DCBX configuration was not updated in FW.
Cause: Relevant implementation was removed as a workaround because of the side effects it caused. Those side effects were caused by two bugs resolved in this version (problem #12 and problem #15 above).
Change: Re-enable DCBX configuration implementation in NPAR-SD mode (remove workaround that prevented it).
Impact: NPAR-SD mode only.
17. Problem: 578xx B0 can't receive traffic in SD mode.
Cause: Inverted port configuration.
Change: Fix port configuration.
Impact: 578xx B0 only.
18. Problem: (FCoE) There was no licensing for FCoE.
Cause: Missing FCoE licensing handling code.
Change: Added the missing code.
Impact: FCoE only.
19. Problem: (NIV) VIF_SET ack was sent twice from driver to MCP and causing logic errors.
Cause: Wrong implementation that if bnx2x_func_state_change returns non zero value it is an error, while in fact only negative value is error.
Change: Assume error only if bnx2x_func_state_change returns negative value.
Impact: NPAR-SD only.
20. Problem: 57840: 4 port mode is not functional.
Cause: Incorrect initialization for this mode.
Change: Fix driver and FW (7.0.7) initialization.
Impact: 57840 only.
21. Problem: 57840: 4 port mode - Grc-timeout appears in syslog.
Cause: Statistics HW is not properly initialized.
Change: Init MSTAT1 correctly.
Impact: 57840 4 port mode only.
22. Problem: DMAE timeout after a few modprobe->ifup->rmmod iterations.
Cause: PGLUE_B was disabled before BMAC reset is completed.
Change: Fixed the relevant driver flow.
Impact: Introduced in 1.64.08.
23. Problem: a. rx error packets detailed in ethtool were increasing all the time while NPAR-SD session is up. b. rx error packets detailed in NPAR-SD protocol STATS_ARRAY_GET request were increasing all the time while NPAR-SD session is up (in UIF type request only).
Cause: all NPAR-SD messages reached host, but are destinated to vif_id of the MCP which is unknown to FW. Therefore, FW marks these packets as per port mf_tag_discard packets.
Yet, these per port statistics were also counted in PMF's per func statistics as rx error packets, and were also sent as rx error bytes in per port stats request of NPAR-SD protocol.
Change: a. Don't count per port mf_tag_discard/outer_vlan_discard packets as per func rx error packets of the PMF. b. Don't count per port mf_tag_discard/outer_vlan_discard packets as per port rx error packets sent in stats request of NPAR-SD protocol.
24. 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.
25. Problem: 578xx unable to link after unload-load sequence.
Cause: Incomplete reset sequence.
Change: Fix reset sequence.
Impact: 578xx.
26. Problem: 578xx 4-port: load/unload test fails when compiled with CNIC.
Cause: Inappropriate client_id configuration for non eth clients.
Change: Fix initialization for 4-port mode.
Impact: 578xx 4port.
27. Problem: 57800 GPHY port (SGMII) LEDs don't work.
Cause: The LED setting routine is called only on 10G link.
Change: Call the LED setting routine even for non-10G link.
Impact: 578xx.
28. Problem: Unable to receive multicast frames on high functions in a multi-function mode.
Cause: approx_mcast_engine_id was not properly initialized in setup ramrod data.
Change: Fixed the relevant driver code.
Impact: Mutli-function mode only.
29. Problem: 578xx 4-port: load/unload test fails when compiled with CNIC.

Change: Force PFC Xon when enabling the device
Impact: 57712 and 578xx
2. Problem: Tx packets are sent with wrong TCP checksum in case of TCP bi-directional scenarios
Cause: Firmware didn't update the L4/L3 checksum correctly in mixed traffic of packets with/without checksum offload
Change: Fixed the relevant firmware flow
Impact: Introduced in 1.64.08
3. 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
Change: Explicitly disable local BHes in bnx2x_run_loopback() to prevent a mentioned above dead-lock situation
Impact: Introduced in 1.60.25
4. Problem: (MF) ethtool -s speed has no effect in multi-function mode
Cause: Address calcutated using func_id instead of vn_id
Change: Fix address calculation

Impact: Introduced in 1.64.00, 57712 only
7. 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
Change: Fix the code handling the parsing_data field of a parsing BD for 57712
Impact: Introduced in 1.53.0a, 57712 only
8. 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
Change: Don't use SAFC parameters unless SAFC MF mode is requested
Impact: Introduced in 1.64.00
9. Problem: Single connection performance is much lower than expected in 57712
Cause: The firmware uses a malfunctioning bit in the HW for single connection optimization
Change: The firmware uses a different bit with similar functionality
Impact: Introduced in 1.64.00 when the optimization was implemented. Doesn't cause any penalty compare to older versions
10. Problem: (FCoE) An FCP_CONF frame was not transmitted when required
Cause: A confirmation indication was not handle properly if the task was from middle path type
Change: Fixed relevant firmware flow
Impact: FCoE only. Exist in all previous FCoE releases
11. Problem: CQ48350, CQ49176, CQ50911 and CQ51200. BCM57712 not linking up after wake on S4 and S5.
Cause: PHY firmware does not have enough time to download in 8073 and 8727 common init.
Change: Poll until firmware is downloaded, and then timeout at 300ms.
Impact: 8727 and 8073 PHY
12. Problem: Statistics were updated in wrong counters
Cause: The per-queue statistic address was miscalculated
Change: Fixed address calculation
Impact: Introduced in 1.64.00
13. Problem: Firmware assert will occur when LSO packets is duplicated in case Tx-switching is enabled and packet is sent without VLAN
Cause: Firmware looses synchronization with packet index which is enforced by firmware for debugging purposes
Change: Fixed relevant firmware flow
Impact: Introduced in 1.64.00
14. Problem: L2 packets which are duplicated in case Tx-switching is enabled may be counted twice in the Tx statistics
Cause: Firmware counts statistics each time a transmission command is sent to hardware, even if the duplicated packet was already sent
Change: Fixed relevant firmware flow
Impact: Introduced in 1.64.00
Enhancements ------------ 1. Request: Use FW 6.4.16
Change: As requested

Change: As requested
7. Request: Add a support for TPA over IPv6 for 57712 and above
Change: As requested
Impact: Introduced in 1.64.10. 57712 and above only
8. Request: Support for forward connection traffic in NPAR-SD mode
Change: TX packets are sent with destination field, on NPAR-SD tag header, which is equal to the source VIF value
Impact: NPAR-SD mode is supported in BCM57712 only
9. Request: Enable Tx switching for 57712
Change: As requested
Impact: 57712 in NPAR mode only
Version 1.64.09 (Nov 18, 2010) ============================== Fixes ----- 1. Problem: CRC errors are seen with line-rate traffic on BCM578xx
Cause: Warpcore microcode was not loaded, and its clock wasn't synchronized well
Change: Load Warpcore microcode and apply clock compensation This change is a temporary work-around which will be embedded in the bootcode later on
Impact: 578xx Only
2. 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
3. Problem: Single Tx L2 connection enhancement feature is broken when FLR is sent on function which is under traffic
Cause: Tx firmware didn't release internal resources, which may be taken by connections that belong to FLRed functions
Change: (in FW 6.4.13) Fixed relevant firmware flow
Impact: Introduced in 1.64.01 (in FW 6.4.0)
4. Problem: Broadcast packets are received on a client which isn't configured to receive them
Cause: The firmware always passed broadcast packets to the leading client even when it wasn't configured to received them
Change: (in FW 6.4.13) Fixed relevant firmware flow
Impact: BCM57711 only, introduced in 1.64.05 (in FW 6.4.7)
5. Problem: TPA does not aggregate packet when RSS disable
Cause: Wrong initialization by firmware
Change: (in FW 6.4.13) Fixed firmware initialization
Impact: Introduced in 1.64.06 (in FW 6.4.9)
6. Problem: (iSCSI, 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: (in FW 6.4.13) Fixed relevant firmware flow
Impact: BCM57710 only, introduced in 1.64.01 (in FW 6.0.0)
7. Problem: Compilation failed on RH5.6
Cause: Redefinition of backported function
Change: Remove the definition from bnx2x code for RH5.6

Cause: Debug info printed with error dbg level
Change: Remove the prints
4. Problem: Weighted fair queuing congestion management doesn't work on BCM57712
Cause: Firmware might send packet to wrong port in case weighted fair queuing is enabled
Change: (in FW 6.4.10) Fixed firmware flow
Impact: Introduced in 1.64.00
5. Problem: Firmware doesn't work correctly for 2 TCP connections with the same toeplitz hash result, when TPA is enabled
Cause: The firmware wrongly invalidated the aggregation for the first connection, when a packet from the second connection arrived
Change: (in FW 6.4.10) Fixed firmware flow
Impact: Introduced in 1.64.03
6. Problem: (CQ50722) When more than 16 TPA aggregations are open, aggregations might not close properly
Cause: The firmware miscalculated the TPA timer address
Cause: TCP window is closed and initiator cannot properly process incoming in-order packets
Change: (in FW 6.4.10) Fixed firmware flow
Impact: Introduced in 1.64.00
8. Problem: False bug-check when trying to set speed in NPAR mode when link is down

Change: Set RSS engine ID in the SETUP ramrod data
Impact: Introduced in 1.64.00. 57711 and 57712 only
2. Problem: (CQ50624) Race between the netdev->open() and the last part of pci_dev->probe() that configures the interrupt mode and adds NAPIs causes kernel panic
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: Unify the slow path flows for all types Client
Change: Handle iSCSI OOO slow path in a NAPI (interrupt driven instead of polling as it used to)

Change: Fix the initialization in FW 6.4.9
Impact: Introduced in 1.64.03, BCM57710/11/11E only
5. Problem: (FCoE) Trying to transmit from invalid host memory address
Cause: Receiving incorrect FCP_XFR_RDY second packet
Change: Rejecting the second FCP_XFR_RDY packet for the specific task
Impact: Introduced in 1.64.00. FCoE only
6. Problem: (FCoE) False timer REC_TOV expiration
Cause: Inappropriate advance of timer counter
Change: Fixed firmware flow in FW 6.4.9

Cause: Changing OX_ID once REC_TOV expiration is detected
Change: Fixed firmware flow in FW 6.4.9
Impact: Exists in all previous FCoE releases
Enhancements ------------ 1. Request: Use FW 6.4.9
Change: As requested
Version 1.64.05 (Oct 20, 2010) ============================== Fixes ----- 1. 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 for such queues
Impact: ESX only
2. Problem: RX broken in MF SD mode
Cause: Improper hw configuration
Change: Write correct values to HW registers
Impact: Intoduced in 1.64.04
3. Problem: Link up event is not reported to the OS
Cause: Inconsistent link report state handling
Change: Change the link report state handling
4. Problem: (ESX, PR379952/PR405074) FW asserts on invalid value in a VLAN field in the start BD (xmit flow)
Cause: The first sg element might not contain all the headers
Change: Do a simple check and if this holds pull tail on the skb
Impact: ESX only. This may happen only when the VMs are using 3.0.x tools
5. Problem: Broadcast packets can be received on the wrong L2 client
Cause: Classification flow was using "unmatched unicast" flag also for broadcast packets
Change: Fixed firmware flow
Impact: 57710 only. Introduced in 1.64.03
6. Problem: When more than 16 TPA aggregations are open, aggregations are not closed properly
Cause: Firmware miscalculated the address for the TPA timers
Change: Fixed firmware flow
Impact: Introduced in 1.64.03
7. Problem: (FCoE) RRQ frame was not sent after abort operation
Cause: Corrupted ABTS ACC frame reported to the driver
Change: Firmware updates the correct R_CTL field in task context
Impact: Introduced in 1.64.00
8. 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
9. Problem: Incorrect HW statistic on 578xx
Cause: Read stats from inexistent address
Change: Adopt statistics collection to avoid reading from the address
Impact: 578xx only
Enhancements ------------ 1. Request: (CQ49997) Implement Bandwidth allocation for Nic partitioning mode
Change: As requested
Impact: 57712 only
2. Request: Use FW 6.4.8
Change: As requested

Change: As requested
4. Request: Add support for BCM57810/57840 adapters
Change: As requested
Version 1.64.04 (Oct 14, 2010) ============================== Fixes ----- 1. 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
2. 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
Change: 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
3. Problem: (CQ50208) ESX4.0/4.1 pNic statstics 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
4. 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
5. 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.
6. Problem: (ESX) packets received on a net queue may arrive after its filters are removed
Cause: filter removal completion is not syncronized 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
7. Problem: (CQ50308) Compilation failure on RHEL6RC1
Cause: Definition of list_rotate_left in bnx2x_compat.h for all kernels from 2.6.34
Change: Remove the definitions for non IOV kernels
Version 1.64.03 (Oct 11, 2010) ============================== Fixes ----- 1. Problem: (ESX) MSI-X was disabled forever after NIC down/up sequence
Cause: MSI-X was explicitly disabled in the bnx2x_close() in ESX driver
Change: Cancel the explicit MSI-X disabling
Impact: ESX only
2. 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
Cause: When multiple consecutive packets are sent on L2 forward connection, firmware might incorrectly manage internal transmission credit
Change: Fixed in FW 6.4.6
Impact: Introduced in 1.64.00 (FW 6.2.0)
4. Problem: LSO packets with large contiguous buffers may not be properly sent to the network

Cause: FCoE ramrods were counted on incorrect SPE pool
Change: Use L5 pool
Impact: Introduced in 1.64.00
2. Problem: Wrong statistic counter might be updated
Cause: (Fixed in FW 6.4.5) In client init the queue statistic address might be calculated wrongly
Change: Fixed the calculation in client init
Impact: Introduced in 1.64.00 (FW 6.2.1)
3. Problem: Congestion management doesn't work properly in case of a single L2 connection scenario on 57712
Cause: In case of a single connection L2 firmware didn't allow pausing transmission which is needed for the congestion management functionality
Change: (Fixed in FW 6.4.5) Firmware now considers congestion management decision to pause transmission
Impact: Introduced in 1.64.00 (FW 6.2.1)
4. Problem: The firmware returned the wrong error state for Ethernet ramrods
Cause: The code in Xstorm didn't save error state correctly
Change: (Fixed in FW 6.4.5) Fixed the relevant flow
Impact: Introduced in 1.64.00 (FW 6.2.0)
5. Problem: PF FLR could hang the chip
Cause: The firmware didn't return activity counter to CFC correctly
Change: (Fixed in FW 6.4.5) Fixed the relevant flow
Impact: Introduced in 1.64.00 (FW 6.2.0)
6. Problem: (CQ49299, PR57004) HW stuck after 8 hours of heavy LSO traffic
Cause: When driver send an LSO packet with total length longer than 64K, the firmware calculate the total SGL length in a uint16 variable which overlaps and causing an erroneous PBF command
Change: (Fixed in FW 6.4.5) Change the counter to be uint32
7. Problem: L2 traffic might be stopped in case of dcb updates COS value for some traffic types
Cause: The firmware didn't return activity counter to CFC correctly
Change: (Fixed in FW 6.4.5) Fixed the relevant flow
Impact: Exists in all previous releases that support dcb updates
Enhancements ------------ 1. Request: Port a new way L2 FW handles FCoE and FIP packets
Change: Starting from FW 6.4.4 L2 FW forwards FCoE and FIP frames to FCoE L2 client unconditionally. This means that there is no need to configure any MAC for an FCoE L2 client any more. So, all such code has been swept out
Impact: Introduced in 1.64.00 (FW 6.4.4)
2. Request: Use FW 6.4.5
Change: As requested
Version 1.64.01 (Sep 20, 2010) ============================== Fixes ----- 1. Problem: BMAC relays control packet to host and BRB is filled with unnecessary packets
Cause: BMAC is configured to relay control packets to host
Change: Configure BMAC not to relay control packets to host
2. Problem: Failed to load high functions in MF mode
Cause: bnx2x was trying to configure the HC for the default SB, which doesn't have it (during FCoE ETH ring configuration)
Change: Exclude HC configuration from FCoE ETH ring initialization
3. Problem: After "Fix 2" packets were silently dropped on the receive side in a SD MF mode
Cause: Tx OUTER VLAN was not properly configured
Change: Properly configure Tx OUTER VLAN in the function start ramrod
4. 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
5. Problem: False link up indication on boards with BCM84823 PHYs
Cause: Not waiting until PHY has come out of reset
Change: Poll on reset bit. Timeout after 1 second
Impact: BCM84823 based boards
6. 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
Enhancements ------------ 1. Request: Add capability to build against SuSE source RPMs
Change: As requested
2. Request: Set drop threshold for receiver lossy COS to 90, when PFC is enabled
Change: As requested
Version 1.64.00 (Aug 31, 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.
Change: In case NIG interrupt mask is cleared during interrupt handling, do not execute link status update routine.
2. 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
Change: Set the pass-through speed to 1G as well when fiber is set to 1G
3. 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.
Change: When ethtool command fail, do not change port type.
Impact: Dual-Media boards
4. Problem: Compilation error on kernels 2.6.34 and later
Cause: netdev_name() defined by both kernel and driver
Change: Fix compat.h for these kernels
5. Problem: 84823 PHY not showing correct Link LED's.
Cause: Incorrectly setting LED Masks
Change: Eliminated offending branch in code
Impact: Introduced in 1.60.24
6. 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
7. 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
8. 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
9. Problem: (ESX) Performance regression found by VmWare
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: ESX only
10. 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: T5.0
11. 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: 1.60.32
12. 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.
13. 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.
14. 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
15. 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
16. 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
17. 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: 1.60.01
18. Problem: The firmware sends an assert when starting the first vf in a passthru mode
Cause: The firmware trys to send an event to the pf, but since the vf was never initialized, the firmware couldn't find which pf to use
Change: The firmware will only send an event in case the function was initialized before. Fixed in FW 6.4.4
Impact: Introduced in FW 6.2.1.1. ESX NPA only
19. 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
Change: Fixed the calculation. Fixed in FW 6.4.4
Impact: Introduced in firmware version 6.0.20
20. Problem: PCI entity wasn't calculated before write event ring element in the initial cleanup and MaliciousVf handlers
Cause: Used wrong PCI entity in the handlers
Change: Calculate the PCI entity before using it. Fixed in FW 6.4.4
Impact: Introduced in FW 6.2.0
21. Problem: In FLR final cleanup flow - in some cases the IGU cleanup command was wrong
Cause: Used wrong parameters for calculation of the function id from Pf or Vf.
Change: Fixed the calculation. Fixed in FW 6.4.4
Impact: Introduced in FW 6.2.0
22. Problem: (ESX PR582737): TX switching along with LSO packet results with HW attention
Cause: LSO packet might be sent on a port which doesn't have sufficient QM credits
Change: LSO packets are sent only if credits were charged for the chosen port (physical vs. loopback). Fixed in FW 6.4.4
Impact: Introduced in first tx switching version 6.1.4
23. Problem: Possible race between dcb update and ethernet tx single connection optimizations
Cause: When Single Eth connection is present it may not allow updating the association of tx queues to COSes
Change: L2 firmware now considers DCB updates and may stop a single connection run to allow DCB configuration update Fixed in FW 6.4.4
Impact: Introduced in version 6.0.15
24. Problem: The firmware didn't support TX switching for MAC-VLAN-PAIR
Cause: The firmware didn't initialize the VFC correctly
Change: Fixed the VFC initialization. Fixed in FW 6.4.4
Impact: Introduced in FW 6.2.0
25. Problem: The error field in ramrod CQE was always sent as 0
Cause: Wrong initialization of the CQE
Change: Sending the right value. Fixed in FW 6.4.4
Impact: Introduced in FW 6.2.0.
26. Problem: The code entered the infinite loop in the Cstorm Common VfZone handler
Cause: Wrong calculation of a VF ID
Change: Fixed the VF ID calculation. Fixed in FW 6.4.4
Impact: Introduced in FW 6.2.0.
27. 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 1.60.29 (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
Change: (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

Change: 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
Change: (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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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: Kernel 2.6.35 and newer
4. Request: Add ethtool port selection for dual media
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
Change: 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()
Change: 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
Change: 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
Change: 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)
Change: As requested
Impact: BCM8727 based boards
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
Change: 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)
Change: (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
Change: (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
Change: (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
Change: 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
Change: 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
Change: (in FW 6.0.27) Fix mss calculation when timestamp option is present
2. Request: Mask protocol violations error detected by chip on HP targets
Change: Masking the specific checks (in FW 6.0.26)
3. Request: Dropping invalid packets which are received during the abort procedure
Change: As requested (in FW 6.0.27)
4. Request: Use FW 6.0.27
Change: As requested
Version 1.60.23 (Jun 10, 2010) ============================== 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
Change: 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
Change: 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
Change: 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
Change: 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()
Change: 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)
Change: 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
Change: 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
Change: Notify user with appropriate message without causing panic
9. Problem: Unable to bring up function 2-7 if MBA didn't configure MACs
Cause: Check for MAC for both multi-function modes
Change: Check for OV tag in Switch-Dependent mode
Impact: Introduced in 1.60.10
Enhancements ------------ 1. Request: Change PXP Write block initialization values in 57712 to help reduce latency
Change: As requested
Impact: 57712 only
Version 1.60.22 (Jun 02, 2010) ============================== Fixes ----- 1. Problem: (CQ47662) "stats updated by DMAE but no MAC active" message while up/down test
Cause: Race on update of statistics' state machine
Change: 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
Change: 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
Change: 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
Change: 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
Change: Validate non NULL pointers before access
6. Problem: (FCoE) FCoE traffic experiences a lot of drops
Enhancements ------------ 1. Request: Don't limit the pause advertisement for large MTU
Change: As requested
Impact: 57712 and above

Change: (in FW 6.0.25) as requested
3. Request: Use FW 6.0.25
Change: As requested
4. Request: Use terminate ramrod for non forwarding clients
Change: As requested
Version 1.60.21 (May 26, 2010) ============================== 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))
Change: 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
Change: Use PCI configuration space to avoid the deadlock
Impact: 57710 only
3. Problem: iSCSI is not functional in switch independent mode
Cause: iSCSI mac was not written into NIG memory
Change: 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
Change: 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
Change: 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)
Change: 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
Change: (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
Change: (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
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
Change: 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()
Change: 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
Change: 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"
Change: Fixed to "than"
5. Problem: (CQ47609) Link Level Pause causes link to pause after PFC has been negotiated
Cause: Wrong MAC registers configuration
Change: 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
Change: 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
Change: 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
Change: 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.
Change: 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
Change: 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.
Change: 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
Change: call to netif_carrier_off() after netif_tx_disable()
Enhancements ------------ 1. Request: Remove redundant LCPLL setting which is done already in the bootcode
Change: As requested
2. Request: (DCBX) Changing PFC RX configuration: In RX COS0 will always be configured to lossy and COS1 to lossless
Change: As requested
3. Request: Remove Outer Vlan configuration for Mac partitioning mode
Change: As requested
4. Request: Use FW 6.0.23
Change: As requested
5. Request: Allow driver compilation with different kernel location
Change: As requested
Version 1.60.18 (May 03, 2010) ============================== Fixes ----- 1. Problem: (CQ47451) iSCSI and FCoE broken and causes kernel panic
Cause: Wrong FW offsets used
Change: fix FW offsets defines
Impact: Introduced in 1.60.17
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
Change: 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
Change: 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
Cause: Firmware caused connection activity-counter to drop to a negative value

Cause: Improper handling of MSI-X enable/disable flow in parity error case
Change: 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
Change: 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
Change: 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)
Change: Set bp->state=OPEN only after all Clients' SETUP ramrods complete
Change: 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)
Change: 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: Driver was reading interrupt status register when IGU was still disabled for the current PF
Change: 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
Change: 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.
Change: 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

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
Change: 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
Change: 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
Change: Configure VLAN removal flag if needed after MTU change

Cause: A race condition between disabling the incoming traffic when unloading and DCC enabling the link
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: fixed
Impact: 57712/57712E only

Cause: Insufficient support in SFP+ module checking
Change: 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
Change: (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
Change: (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
Change: (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
Change: (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.
Change: 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.
Change: 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
Change: Using fpid moved to later stages after its initialization
Impact: None
Version 1.53.12 (Nov 16, 2009) ==============================
Fixes ----- 1. Problem: CQ41232: Management gets incorrect AN and FC bit values.
Cause: FC wasn't updated correctly during link up event
Change: Extract all status_link information correctly
Impact: None
2. Problem: CQ36401: Excessive link down messages when driver is unloaded
Cause: Link event is reported for every link event, even when link is not changed
Change: Do not report link change unless there's actually link link change
Impact: None
3. Problem: BCM8481 doesn't negotiate FC capabilities
Cause: FC capabilities weren't advertised during phy initialization
Change: Set BCM8481 FC capabilities during init stage
Impact: None
4. Problem: (FCoE) Completions are not arrived on open tasks
Cause: Connection does not register to QM since SQ producer/consumer
Change: Fixed in FW 5.3.14: Set BCM8481 FC capabilities during init stage
Impact: None
Enhancement ----------- 1. Request: Support bootcode on 57712
Change: As requested
Impact: 577712 Only
2. Request: Allocate available MSI-X vectors in normal mode
Change: As requested
Impact: None
3. Request: Use multi cpu rx when using msix in kernels without new napi
Change: As requested
Impact: None
4. Request: support correct number of iSCSI and FCoE sessions in the HW initializations
Change: As requested
Impact: None
5. Request: support any number of L2 queues in the HW initializations
Change: As requested
Impact: None
6. Request: Hanlde both Tx and Rx in NAPI
Change: As requested
Impact: None
7. Request: Support 4-port mode for 57712
Change: As requested
Impact: None
8. Request: Use FW 5.3.14
Change: As requested
Impact: None
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
Change: 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
Change: 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
Change: 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
Change: Added mask for write access
Impact: None

Enhancement ----------- 1. Request: Use FW 5.3.10
Change: As requested
Impact: None
Version 1.53.xx (Oct xx, 2009) ==============================
Enhancement ----------- 1. Request: Improve times for ifconfig up/down (slow 57712 chip revision)
Change: As requested
Impact: None
Version 1.53.xx (Oct xx, 2009) ==============================
Enhancement ----------- 1. Request: Add support for EMAC loopback for FPGA
Change: As requested
Impact: None
Version 1.53.7 (Oct 22, 2009) ==============================
Enhancement ----------- 1. Request: Use FW 5.3.9
Change: As requested
Impact: None
2. Request: Remove compilation flag for BCM57712/BCM57712E/BCM57713/BCM57713E
Change: As requested
Impact: None
Version 1.53.6 (Oct 21, 2009) ==============================
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"
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: Fixed in FW 5.3.8
Impact: None
6. Problem: FCoE INIT ramrod was never completed
Cause: Reading from inappropriate VQ in Tstorm
Change: 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
Change: 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
Change: MAC initializaton fixed
Impact: None
2. Problem: 57712 failed to bring up interface
Cause: Unhandled attention interrupt caused processor to stall
Change: 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

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.
Change: 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.
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Impact: None
7. Request: (CQ41112) - PHY LED Programming for BCM8481 on BlackBird (BCM957711A1100G) Production Board
Change: As requested
Impact: None
8. Request: Increase DMAE max write size for 57711/57711E
Change: As requested
Impact: None
9. Request: Not handling statistics in panic condition
Change: As requested
Impact: None
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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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.
Change: 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
Change: 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
Change: 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
Change: 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
Change: (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)
Change: 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
Change: 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
Change: 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
Change: 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.
Change: 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
Change: 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
Change: 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
Change: 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()
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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)
Change: 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) =============================
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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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.
Change: 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
Change: 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
Change: When setting 10G, enforce 10G configuration, and not relay on the default configuration.
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
Change: 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
Change: 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
Change: 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
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
Change: 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
Change: 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.
Change: 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
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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
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)
Change: 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
Change: 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
Change: 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
Change: 1. Microcode download requires write of another register 2. Read from "Limiting/LRM mode" register before setting Limiting mode
Cause: Tx wasn't properly disabled in the 'close' flow
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: Don't clear the "MSI reconfigure enable" bit
Impact: None
7. Problem: Uninitialized HW blocks
Cause: XCM and BRB1 port init part were missing
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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.
Change: 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
Change: 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)
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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.
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Cause: Inefficient implementation of ring management in firmware
Change: 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
Change: 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
Change: 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.
Change: 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
Change: 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
Change: 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)
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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.
Change: 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
Change: Fixed in FW 4.6.10
Impact: None
5. Problem: (CQ37090) Placement of RQ data to wrong address
Cause: ASM problem
Change: Fixed in FW 4.6.10
Impact: None
6. Problem: (CQ36912) BSOD when destroying erroneous connections
Cause: Activity count leak
Change: Fixed in FW 4.6.10
Impact: None
7. Problem: (CQ 36987) Unable to perform media changer/tape functions
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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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()
Change: 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.
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: Clear FW statistics area when loading the driver
Cause: Did not apply the right mask on the HW report caused some false positives
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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
Change: 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 ------------ 1. Request: Error messages might be displayed in unload
Change: Check work only on the tx fast path and call bnx2x_tx_int() to handle it. Rx work is handled during halt ramrod
Impact: None
2. Request: Indicate that there is no WoL support for functions higher than 1 (only 0 and 1 should support WoL)
Change: As Requested
Impact: None
3. Request: Pause in 57711E mode always advertise both Rx and Tx regardless of frame size
Change: As Requested
Impact: None
4. Request: Skb's marked as CHECKSUM_UNNECESSARY (TPA'ed) were passed to the net stack even if user disabled checksum offloading.
Change: Disable TPA if Rx checksum offloading is disabled.
Impact: There is no way to enabling TPA in kernels older than 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 setting up the internal PHY. When needed, only the external PHY will be configured to autoneg. The internal PHY will be set to the obtained speed
Impact: None
7. Request: Skb's marked as CHECKSUM_UNNECESSARY (TPA'ed) were passed to the net stack even if user disabled checksum offloading.
Change: Disable TPA if Rx checksum offloading is disabled.
Impact: None
8. Request: Incorporated latest firmware 4.6.7 - Add support for priority-based ETH TX queues and enable SAFC pausing per queue
Change: As requested
Impact: None
Version 1.46.1 (June 25, 2008) ==============================
Enhancements ------------ 1. Request: Use FW version 4.6.2
Change: As Requested
Impact: None
Version 1.45.6 (June 23, 2008) ==============================
Fixes ----- 1. Problem: (CQ35672, CQ35818) Changing MTU under traffic causes driver hang
Cause: A rare case of LSO packet alignment, relatively to MSS, caused a HW debug checking for end of packet to fail
Change: In computing the end of packet flag, the calculation of the total packet length was modified
Impact: None
2. Problem: Possible memory corruption on kernels with 64K page size
Cause: Inconsistency in using page macros
Change: Use only BCM page macros
Impact: None
Enhancements ------------ 1. Request: Add support for TPA (LRO) setting via ethtool
Change: As Requested
Impact: Kernels after 2.6.26 use this interface to turn off TPA when forwarding enabled due to the limitation of no forwarding (bridging) and TPA together
Version 1.45.5 (June 17, 2008) ==============================
Fixes ----- 1. Problem: (CQ35691) Undefined symbol __udivdi3 when compiled on 32-bit platforms.
Cause: There was 64-bit division
Change: Reordered the arithmetic expression in order to eliminate the 64-bit division
Impact: None.
2. Problem: (CQ35644) Tx mulicast counter does not increment
Cause: start_xmit sets the unicast flag for all packet types
Change: Remove the broadcast and mulicast counters
Impact: None
3. Problem: (CQ35836) Ethtool reports wrong speed when set via CLP
Cause: get_settings returns always the max BW set via CLP without considering the actual link speed
Change: Return the min between the max BW set via CLP and the actual link speed
Impact: None
4. Problem: (CQ35859) Ethtool -S reports many jumbo tx packets with MTU set to 1500
Cause: There is a different in tx histogram statistics between EMAC and BigMAC
Change: Use NIG stats counters instead
Impact: None
5. Problem: (CQ35114) Self test failure on some systems
Cause: pcie_rst_b test can be set and should not be categorized as ERROR
Change: Change pcie_rst_b test priority from ERROR to WARNING
Impact: None
Enhancements ------------ 1. Request: Remove non-coherent stats in 57711E
Change: As Requested
Impact: None
2. Request: Remove xSEM_REG_INT_TABLE from memory test
Change: As Requested
Impact: None
Version 1.45.4 (June 10, 2008) ==============================
Fixes ----- 1. Problem: (CQ34905) load/unload causes link detect failure
Cause: Handling of link events during load wasn't protected
Change: Add synchronization in handling of link events during driver load
Version 1.45.1 (May 26, 2008) =============================
Fixes ----- 1. Problem: (CQ34964) ethtool -a/A is broken
Cause: The autoneg define changed to value of zero and broke the code
Change: Use comparison instead of bit-wise logical and
Impact: None
2. Problem: (CQ35123) Support for 32bit Kernels is broken
Cause: The TPA code had a 64 bit address that broke the 32bits support
Change: Fixed the upper 32bits of the address to zero in 32bit Kernel
Impact: None
3. Problem: (CQ35123) Support for Big-endian is broken
Cause: The TPA and SGE code was not big-endian compliant
Change: The necessary le_to_cpu were added
Impact: None
4. Problem: Failed to work on emulation with MCP
Cause: The time interval between the pulses towards the MCP was the same for ASIC and emulation
Change: Increased the time interval between MCP pulses for emulation/FPGA
Impact: None
5. Problem: (CQ34313) Compilation error on SuSE
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
Change: Use static allocation for the fast-path structures
Impact: None
Enhancements ------------ 1. Request: (CQ34895) Change Linux Driver Disk Images from Floppy to ISO Format
Change: As Requested
Impact: None
2. Request: (CQ34931, CQ34976) Replace RH4.5 binaries with RH4.6

Change: As Requested
Impact: None
6. Request: Support Transparent Packet Aggregation (TPA) for 57711E
Change: As Requested
Impact: None
7. Request: Support WoL
Change: As Requested. This feature requires bootcode 4.4.7 or later
Impact: None
8. Request: Not allowing any ethtool link change (speed and flow control) in 57711E

Change: TPA is now supported, but the throughput is still lower than in the DEMO_TPA version - a new version with enhanced throughput is being constructed
Impact: None
2. Request: (CQ34011) Add module parameter to disable TPA
Change: As requested. For now, TPA is always disabled on 57711
Impact: None
3. Request: CNIC Support
Change: As requested. By default, CNIC support is not part of the bnx2x - BCM_CNIC should be defined to enable it.
Impact: None
Version 1.44.4 (March 20, 2008) ===============================
Fixes ----- 1. Problem: DEMO_TPA was broken on 0.44.3
Cause: Compilation problem due to MACRO rename
Change: Rename the MACRO for DEMO_TPA as well
Impact: None
2. Problem: (CQ43424) Cannot link SFP module at 1G with Dell PowerConnect 6224
Cause: The Dell switch supports only autoneg and not forced 1G
Change: Changed the 1G implementation to autoneg with only 1G advertisement
Impact: When choosing 1G speed, the speed is achieved via autoneg and not forced
Enhancements ------------ 1. Request: Support Emulation, FPGA and ASIC in a single module file
Change: Changed the init values and the init routine to support all the compilation of 57710/57711 ASIC/CHIP/EMUL
Impact: The size of the binary and the source code is bigger mainly due to having two ASM images
2. Request: Add link update support for 57711

Impact: None
Version 1.42.3 (February 28, 2008) ==================================
Fixes ----- 1. Problem: Changing the link speed to "autoneg on" the A1022G will cause driver failure
Cause: This board is using TP for the 10G interface, but the command was interpreted as a request to move to the 1G interface which is inactive on this board
Change: Do not support switching interfaces since no production board has this feature
Impact: A user will not be able to switch between the two valid interfaces of the T1001 test board without changing the nvram configuration
Version 1.42.2 (February 20, 2008) ==================================
Fixes ----- 1. Problem: TSO is not working against some none Linux clients

Change: The workaround was added
Impact: None
Version 0.40.18 (January 03, 2008) ==================================
Fixes ----- 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.

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) ==================================
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
Change: 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
Change: 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
Change: 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
Change: 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.

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.
