From 231835e4163cf14c90e295f1729004f571ee1cc7 Mon Sep 17 00:00:00 2001 From: Ajit Khaparde Date: Tue, 13 Oct 2009 01:46:29 +0000 Subject: [PATCH] igb: Fix erroneous display of stats by ethtool -S Commit 337e067d overlooked the way offsets for netdev stats were considered. Because of this some of the stats shown by ethtool -S were wrong. This patch fixes it. Signed-off-by: Ajit Khaparde Signed-off-by: David S.
