ixgbe patch to provide NIC's tx/rx counters via ethtool
When LRO is enabled, the received packet and byte counters represent the
LRO'd packets, not the packets/bytes on the wire. The Intel 82599 NIC has
registers that keep count of the physical packets. Add these counters to
the ethtool stats. The byte counters are 36-bit, but the high 4 bits were
being ignored in the 2.6.31 ixgbe driver: Read those as well to allow
longer time between polling the stats to detect wraps.
