bnx2.c (incorrectly) sets current->state directly to
TASK_UNINTERRUPTIBLE, without going through set_task_state(). However
all the code wants to do is an msleep so just make it do that instead...

The device would not resume properly if it was shutdown before the system
was suspended. In such scenario where the netif_running state is 0,
bnx2_suspend() would not save the PCI state and so the memory enable bit
and bus master enable bit would be lost.
We fix this by always saving and restoring the PCI state in
bnx2_suspend() and bnx2_resume() regardless of netif_running() state.
Update version to 1.6.4.

All drivers implement ethtool get_perm_addr the same way -- by calling
the generic function. So we can inline the generic function into the
caller and avoid going through the drivers.

The NVRAM interface is slightly modified on the 5709. To properly
support it, we need to change the buffered flag in the flash data
structure into multiple flags to indicate buffered operation, address
translation, and the use of write enable (WREN). The 5709 flash
only requires the buffered operation bit to be set.

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.
Compile tested with make all{yes,mod}config on x86_64 and i386.

In addition to the periodic heartbeat, we're adding a heartbeat
request interrupt when the heartbeat is late. This is needed during
netpoll where the timer is not available. -rt kernels will also
benefit since the timer is not as accurate.
[ We discussed this patch last time and we decided that the -rt
kernel problem alone did not justify this patch. I think the
netpoll problem makes this patch necessary. ]

Spurious interrupts are often encountered especially on systems
using the 8259 PIC mode. This is because the I/O write to deassert
the interrupt is posted and won't get to the chip immediately. As
a result, the IRQ may remain asserted after the IRQ handler exits,
causing spurious interrupts.
Add read back to flush the I/O write to deassert the IRQ immediately.
We also store the last_status_idx immediately in the IRQ handler to
help detect whether the interrupt is ours or not when the IRQ is
entered again before ->poll gets called.

Modify the driver's ethtool_ops->get_settings and set_settings
functions to support remote PHY. Users control the remote copper
PHY settings by specifying link settings for the tp (twisted pair)
port.
The nway_reset function is also modified to support remote PHY.
mii-tool operations are not supported on remote PHY and we will

In blade servers, the Serdes PHY in 5708S can control the remote
copper PHY through autonegotiation on the backplane. This patch adds
the logic to interface with the firmware to control the remote PHY
autonegotiation and to handle remote PHY link events.
When remote PHY is present, the 5708S Serdes device practically
becomes a copper device with full control over the 1000Base-T
link settings.

The existing model for checksum offload does not correctly handle
devices that can offload IPV4 and IPV6 only. The NETIF_F_HW_CSUM flag
implies device can do any arbitrary protocol.
This patch:
* adds NETIF_F_IPV6_CSUM for those devices
* fixes bnx2 and tg3 devices that need it
* add NETIF_F_IPV6_CSUM to ipv6 output (incl GSO)
* fixes assumptions about NETIF_F_ALL_CSUM in nat
* adjusts bridge union of checksumming computation

The statistics block DMA on 5708 can be messed up occasionally on the
average of about once per hour. If the user is reading the counters
within one second after the corruption, the counters will be all
messed up. One second later, the counters will be ok again until the
next corruption occurs.
The workaround is to disable the periodic statistics DMA. Instead,
we manually trigger the DMA once a second in bnx2_timer(). This
manual trigger of the DMA avoids the problem.
As a consequence, we can only allow 0 or 1 second settings for
ethtool -C statistics block.

There's a bug in the driver that only initializes half of the context
memory on the 5708. Surprisingly, this works most of the time except
for some occasional netdev watchdogs when sending a lot of 64-byte
packets. The fix is to add the missing code to initialize the 2nd
halves of all context memory.
