From aad719182d9c6a785931efe87b978eb6f7742e0e Mon Sep 17 00:00:00 2001 From: Ben Greear Date: Wed, 30 Sep 2009 12:08:16 +0000 Subject: 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.
