Commit 506724c463fcd63477a5e404728a980b71f80bb7 "tg3: Override clock,
link aware and link idle mode during NVRAM dump" changed the timeout
value for nvram command execution from 100ms to 1ms. But the 1ms
timeout value was only sufficient for nvram read operations but not
write operations for most of the devices supported by tg3 driver.
This patch sets the MAX to 50ms. Also it uses usleep_range instead
of udelay.

tg3: Clear NETIF_F_TSO6 flag before doing software GSO

Commit d3f6f3a1d818410c17445bce4f4caab52eb102f1 ("tg3: Prevent page
allocation failure during TSO workaround") modified driver logic
to use tg3_tso_bug() for any TSO fragment that hits hardware bug
conditions thus the patch increased the scope of work for tg3_tso_bug()
to cover devices that support NETIF_F_TSO6 as well. Prior to the
patch, tg3_tso_bug() would only be used on devices supporting
NETIF_F_TSO.

A regression was introduced for IPv6 packets requiring the workaround.
To properly perform GSO on SKBs with TCPV6 gso_type, we need to call
skb_gso_segment() with NETIF_F_TSO6 feature flag cleared, or the
function will return NULL and cause a kernel oops as tg3 is not handling
a NULL return value. This patch fixes the problem.

tg3: Override clock, link aware and link idle mode during NVRAM dump

When cable is not present the clock speed of some of the devices is
reduced based upon power saving mode setting in NVRAM. Due to this
NVRAM reads take long time to complete as a result CPU soft lockup
message is seen. Fix is to override clock, disable link aware and link
idle modes before NVRAM reads and restore them back after the reads
are complete. During this period also check if the thread needs to be
rescheduled and if there are any signals to handle.

Also decrease the NVRAM command execution timeout value to 1ms.

tg3: Prevent page allocation failure during TSO workaround

If any TSO fragment hits hardware bug conditions (e.g. 4G boundary), the
driver will workaround by calling skb_copy() to copy to a linear SKB. Users
have reported page allocation failures as the TSO packet can be up to 64K.
Copying such a large packet is also very inefficient. We fix this by using
existing tg3_tso_bug() to transmit the packet using GSO.

tg3: Don't modify ip header fields when doing GSO

tg3 uses GSO as workaround if the hardware cannot perform TSO on certain
packets. We should not modify the ip header fields if we do GSO on the
packet. It happens to work by accident because GSO recalculates the IP
checksum and IP total length.

Also fix the tg3_start_xmit comment to reflect that this is the only
xmit function for all devices.

tg3: Do not include vlan acceleration features in vlan_features

Including hardware acceleration features in vlan_features breaks
stacked vlans (Q-in-Q) by marking the bottom vlan interface as
capable of acceleration. This causes one of the tags to be lost
and the packets are sent with a sing vlan header.

tg3: Poll cpmu link state on APE + ASF enabled devices

On ASF enabled devices where the mgmt firmware runs on the application
processing engine, there is a race between the tg3 driver processing a
link change event and the ASF firmware clearing the link changed bit in
the EMAC status register. This leads to link notifications to the driver
sometimes getting lost.

Poll the CPMU link state as a backup for the normal interrupt path
update if ASF is enabled.

tg3: Set the MAC clock to the fastest speed during boot code load

On the 5717, 5718 and 5719 devices, the bootcode runs slower when any
port doesn't have a link due to clock speed slowing down as part of the
link-aware feature. This leads to the driver timing out waiting for the
bootcode signature.

This patch overrides the clock policy to the highest frequency just before
reset and restores it after the bootcode is up.

tg3: Initialize REG_BASE_ADDR at PCI config offset 120 to 0

The new tg3 driver leaves REG_BASE_ADDR (PCI config offset 120)
uninitialized. From power on reset this register may have garbage in it. The
Register Base Address register defines the device local address of a
register. The data pointed to by this location is read or written using
the Register Data register (PCI config offset 128). When REG_BASE_ADDR has
garbage any read or write of Register Data Register (PCI 128) will cause the
PCI bus to lock up. The TCO watchdog will fire and bring down the system.

PCI / tg3: Give up chip reset and carrier loss handling if PCI device is not present

Modify tg3_chip_reset() and tg3_close() to check if the PCI network
adapter device is accessible at all in order to skip poking it or
trying to handle a carrier loss in vain when that's not the case.
Introduce a special PCI helper function pci_device_is_present()
for this purpose.

Of course, this uncovers the lack of the appropriate RTNL locking
in tg3_suspend() and tg3_resume(), so add that locking in there
too.

These changes prevent tg3 from burning a CPU at 100% load level for

tg3: Expand led off fix to include 5720

Commit 989038e217e94161862a959e82f9a1ecf8dda152 ("tg3: Don't turn off
led on 5719 serdes port 0") added code to skip turning led off on port
0 of the 5719 since it powered down other ports. This workaround needs
to be enabled on the 5720 as well.

drivers:net: Convert dma_alloc_coherent(...__GFP_ZERO) to dma_zalloc_coherent

__GFP_ZERO is an uncommon flag and perhaps is better
not used. static inline dma_zalloc_coherent exists
so convert the uses of dma_alloc_coherent with __GFP_ZERO
to the more common kernel style with zalloc.

Remove memset from the static inline dma_zalloc_coherent
and add just one use of __GFP_ZERO instead.

Trivially reduces the size of the existing uses of
dma_zalloc_coherent.

Realign arguments as appropriate.

net: tg3: fix NULL pointer dereference in tg3_io_error_detected and tg3_io_slot_reset

Commit d8af4dfd8 ("net/tg3: Fix kernel crash") introduced a possible
NULL pointer dereference in tg3 driver when !netdev || !netif_running(netdev)
condition is met and netdev is NULL. Then, the jump to the 'done' label
calls dev_close() with a netdevice that is NULL. Therefore, only call
dev_close() when we have a netdevice, but one that is not running.

tg3: Allow NVRAM programming when interface is down

Previously, when the interface was brought down, the driver would set
the power state to D3hot. In D3hot, we don't have access to the NVRAM.
This patch removes the call to set the power state to PCI_D3hot in
close. A following patch will implement the shutdown handler to properly
set the D3hot state when the system is going down.

Doing the above means that the TG3_PHYFLG_IS_LOW_POWER should not be
checked to validate access to the NVRAM.

During probe, the driver is incorrectly switching the power to Vaux on

drawing maximum power. We also definitely have Vmain available. It
doesn't make sense to switch to Vaux since it has a lesser maximum power
draw and we might go over the limit. On a new system, we observe that
not all ports are recognized in some of the slots with this call in
place.

net/tg3: Avoid delay during MMIO access

When the EEH error is the result of a fenced host bridge, MMIO accesses
can be very slow (milliseconds) to timeout and return all 1's,
thus causing the driver various timeout loops to take way too long and
trigger soft-lockup warnings (in addition to taking minutes to recover).

It might be worthwhile to check if for any of these cases, ffffffff is
a valid possible value, and if not, bail early since that means the HW
is either gone or isolated. In the meantime, checking that the PCI channel
is offline would be workaround of the problem.

tg3: Prevent system hang during repeated EEH errors.

The current tg3 code assumes the pci_error_handlers to be always called
in sequence. In particular, during ->error_detected(), NAPI is disabled
and the device is shutdown. The device is later reset and NAPI
re-enabled in ->slot_reset() and ->resume().

In EEH, if more than 6 errors are detected in a hour, only
->error_detected() will be called. This will leave the driver in an
inconsistent state as NAPI is disabled but netif_running state is still
true. When the device is later closed, we'll try to disable NAPI again
and it will loop forever.

We fix this by closing the device if we encounter any error conditions
during the normal sequence of the pci_error_handlers.

tg3: Wait for boot code to finish after power on

Some systems that don't need wake-on-lan may choose to power down the
chip on system standby. Upon resume, the power on causes the boot code
to startup and initialize the hardware. On one new platform, this is
causing the device to go into a bad state due to a race between the
driver and boot code, once every several hundred resumes. The same race
exists on open since we come up from a power on.

This patch adds a wait for boot code signature at the beginning of
tg3_init_hw() which is common to both cases. If there has not been a
power-off or the boot code has already completed, the signature will be
present and poll_fw() returns immediately. Also return immediately if
the device does not have firmware.

tg3: Ensure boot code has completed initialization before accessing hardware

After resetting the device, the driver waits for a signature to be
updated to know that firmware has completed initialization. However, the
call to tg3_poll_fw() is being done too late and we're writing to the
GRC_MODE register before it has completely initialized, causing
contention with firmware. This logic has existed since day one but is
causing PCIE link to go down randomly at startup on one platform once
every few hundred reboots.

Move the tg3_poll_fw() up to before we write to the GRC_MODE register
after reset.

Using bool can make code more readable.

Convert uses and tests of int to bool.

This also makes a comparison of tg3->link_up
(itself bool) a bool comparison instead of int.

Reorder stack variable declarations to make
bool fit declaration holes where appropriate.

tg3: Pull the phy advertised speed and flow control settings on driver load

Normally on driver load, we set the default settings for speed and flow
control. However, if the default setting is not compatible with the current link
state, we would autonegotiate and cause a link flap. To avoid this, we
pull the current advertised settings into the config.

A second scenario is if a user changes the speed/duplex/fc settings when
the interface is down. In this case we must not pull the settings from
the phy and overwrite user settings. We avoid that by checking the
USER_CONFIGURED flag.

tg3: Add support for link flap avoidance

This patch and the following two patches add support for link flap avoidance
by maintaining the link on power down. This feature is required for
management capable devices to have the management connection
uninterrupted on driver reload, reboot and interface up/down.

The other pros of this feature are
- It speeds up boot up time by several seconds as DHCP addresses can be
acquired faster.
- It avoids lengthy Spanning Tree delay.

On powerup the hardware brings up the phy with default settings. If the
link is not up, the management software configures the phy to gigabit
and starts autonegotiate. Subsequently, as long as the link is up, the
driver and management refrain from resetting and/or changing any
configuration that the link depends on.

The LNK_FLAP_AVOID setting is an NVRAM user configurable bit and is
disabled by default. If this setting is enabled, we skip powering down
the phy and resetting it.

A second NVRAM setting is 1G_ON_VAUX_OK (off by default). This adds
support for gigabit link speed when device is on auxiliary power.

flow control is not a PHY setting. Later on, we'll call

Commit 184b89044fb6e2a74611dafa69b1dce0d98612c6 ("tg3: Use VPD fw version
when present") introduced VPD parsing that contained a potential length
overflow.

Limit the hardware's reported firmware string length (max 255 bytes) to
stay inside the driver's firmware string length (32 bytes). On overflow,
truncate the formatted firmware string instead of potentially overwriting
portions of the tg3 struct.

tg3: 5715 does not link up when autoneg off

Commit d13ba512cbba7de5d55d7a3b2aae7d83c8921457 ("tg3: Remove
SPEED_UNKNOWN checks") cleaned up the autoneg advertisement by
removing some dead code. One effect of this change was that the
advertisement register would not be updated if autoneg is turned off.

This exposed a bug on the 5715 device w.r.t linking. The 5715 defaults
to advertise only 10Mb Full duplex. But with autoneg disabled, it needs
the configured speed enabled in the advertisement register to link up.

This patch adds the work around to advertise all speeds on the 5715 when
autoneg is disabled.

tg3: Update link_up flag for phylib devices

Commit f4a46d1f46a8fece34edd2023e054072b02e110d introduced a bug where
the ifconfig stats would remain 0 for phylib devices. This is due to
tp->link_up flag never becoming true causing tg3_periodic_fetch_stats()
to return.

The link_up flag was being updated in tg3_test_and_report_link_chg()
after setting up the phy. This function however, is not called for
phylib devices since the driver does not do the phy setup.

This patch moves the link_up flag update into the common
tg3_link_report() function that gets called for phylib devices as well
for non phylib devices when the link state changes.

To avoid updating link_up twice, we replace tg3_carrier_...() calls that
are followed by tg3_link_report(), with netif_carrier_...(). We can then
remove the unused tg3_carrier_on() function.

Upper case macros for various chip attributes are slightly
difficult to read and are a bit out of characterto the other

Convert:

GET_ASIC_REV(tp->pci_chip_rev_id) -> tg3_asic_rev(tp)
GET_CHIP_REV(tp->pci_chip_rev_id) -> tg3_chip_rev(tp)

Remove:
GET_METAL_REV(tp->pci_chip_rev_id) -> tg3_metal_rev(tp) (unused)

Add:
tg3_chip_rev_id(tp) for tp->pci_chip_rev_id so access styles
are similar to tg3_asic_rev and tg3_chip_rev.

These macros are not converted to static inline functions
because gcc (tested with 4.7.2) is currently unable to
optimize the object code it produces the same way and code
is otherwise larger.

- For the 57766 and non Ax versions of 57765, bootcode needs to setup

Unfortunately, it does not have enough room in the selfboot case (i.e.
devices with no NVRAM). The driver needs to implement this.

- For performance reasons, the 2k DMA engine mode on the 57766 should
be enabled and dma size limited to 2k for standard sized packets.
