ixgb: Fix erroneous display of stats by ethtool -S
Commit 5675f221 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 <ajitk@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>
