Adds PCI Error recovery callbacks to the Intel 10-gigabit ethernet ixgb
device driver. Lightly tested, works.

Both pci_disable_device and ixgb_down would access the device. It doesn't
follow Documentation/pci-error-recovery.txt that error_detected shouldn't do
any access to the device.

A recent patch in -mm3 titled
"gregkh-pci-pci-don-t-enable-device-if-already-enabled.patch" causes
pci_enable_device() to be a no-op if the kernel thinks that the device is
already enabled. This change breaks the PCI error recovery mechanism in
the e100 device driver, since, after PCI slot reset, the card is no longer
enabled. This is a trivial fix for this problem. Tested.

The current probe table causes ledma and lebuffer
"le" devices to get probed twice which is not what
we want.
Match just "le" and look directly at the parent to get the correct
top-level node information.

Found by inspection. The STRIP driver does neigh_lookup() but never
releases. This driver shouldn't being doing gratuitous arp anyway.
Untested, obviously, because of lack of hardware.

Several people run into the situation where the E100
EEPROM contents are fine, but the checksum hasn't been
set properly. This renders the device useless for
them even though it would function correctly.
The default is off, which retains the current behavior.

The code to handle cloned skb overwriting is unnecessary in the
sky2 driver and is buggy. The bug is that pskb_expand_head can change the
skb but the driver has already mapped in the header.
Since the sky2 hardware doesn't need to overwrite memory, the buggy
code can just be removed; it was mistakenly copied from the tg3
driver.

Some recent myri10ge firmwares support multicast filtering as well
as an extended mcp_irq_data structure (64 instead of 40 bytes).
The new command MXGEFW_CMD_SET_STATS_DMA_V2 is used to check
whether the firmware support those. mgp->fw_multicast_support
is defined accordingly.
When fw_multicast_support is set, some new multicast filtering
commands is passed to the board in myri10ge_set_multicast_list().

want to avoid useless flooding in the logs.
