Add 'supports_ipv6' flag to struct ip_vs_scheduler to indicate whether a
scheduler supports IPv6. Set the flag to 1 in schedulers that work with
IPv6, 0 otherwise. This flag is checked in a later patch while trying to
add a service with a specific scheduler. Adjust debug in v6-supporting
schedulers to work with both address families.

Add some debugging macros that allow conditional output of either v4 or v6

string representations into it from another macro which can only be used
when inside the outer one.

  2. Fix write eeprom to write full words rather than only 16 bits
    Luckly the vendor doesn't provide EEPROM in Linux format so it must never

Merge branch 'r8169-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/romieu/netdev-2.6 into upstream-next

This change makes it so only one srrctl register is programmed per VMDq id, and if VMDq is not enabled it is one register per RSS queue.  Currently this function is working correctly for the multiqueue RSS and single queue cases, but if any advances features such as VMDq or DCB would have been enabled this function would have caused issues as it was not correct.

the driver was misinterpreting rx_csum return value in the descriptor
so occassionally we would indicate an rx_csum error in our stats
when there was none.  This would have no effect on traffic because
we would just hand the packet to the stack anyway without the offload
flag set, but would increase CPU for those packets that needed a recompute.
