Every 20 descriptors turns out to be to few append commands with
newer/faster CPUs. Pushing every 4 still cuts down on MMIO writes to an
acceptable level without letting the DMA engine run out of work.

mtdoops wasn't ensuring data was flushed to flash in crash situations
after recent changes in mainline kernels as tracking the
oops_in_progress variable was no longer enough. We can use the "unblank"
console call as a sync call to tell us to write out the buffer though.
Therefore add a sync function to mtdoops and call this when console
unblank events occur.

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.

This driver handles only L2TP data frames; control frames are handled
by a userspace application. It implements L2TP using the PPPoX socket
family. There is a PPPoX socket for each L2TP session in an L2TP
tunnel. PPP data within each session is passed through the kernel's
PPP subsystem via this driver. Kernel parameters of each socket can be
read or modified using ioctl() or [gs]etsockopt() calls.

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 IB CM should include the HCA ACK delay when calculating the local

enough relative to the packet life time, then if it is not taken into
account, the calculated timeout value ends up being too small, which
can result in "retry exceeded" errors.
