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
return -EOPNOTSUPP.

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.

called in bnx2_init_one(). We need to call pci_set_drvdata() and

also needs to be moved to bnx2_open() to avoid race conditions with

This patch splits the vlan_group struct into a multi-allocated struct. On
x86_64, the size of the original struct is a little more than 32KB, causing
a 4-order allocation, which is prune to problems caused by buddy-system
external fragmentation conditions.
I couldn't just use vmalloc() because vfree() cannot be called in the

I don't see any reason why we need pci_msi_quirk, quirk code can just
call pci_no_msi() instead.
Remove the check of pci_msi_quirk in msi_init(). This is safe as all
calls to msi_init() are protected by calls to pci_msi_supported(),
which checks pci_msi_enable, which is disabled by pci_no_msi().
The pci_disable_msi routines didn't check pci_msi_quirk, only
pci_msi_enable, but as far as I can see that was a bug not a feature.
