From 094919a4b0c56d6afbfb5ea14567fbb2f8d47554 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Tue, 27 Oct 2009 15:49:49 +0000 Subject: igb: remove rx checksum good counter Counting packets with a good checksum can cause a significant amount of cache line bouncing due to the shared counter being written to by all of the queues. In order to avoid this I am removing the counter since we still have the checksum failed counter which will tell us if there are any issues.
