From: Kulikov Vasiliy Date: Mon, 5 Jul 2010 02:14:17 +0000 (+0000) Subject: natsemi: Use the instance of net_device_stats from net_device. X-Git-Tag: v3.12-rc1~9497^2~347 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2321e80ac84cc616edda926aa1932b344409dccc;p=kernel%2Fkernel-generic.git natsemi: Use the instance of net_device_stats from net_device. Since net_device has an instance of net_device_stats, we can remove the instance of this from the adapter structure. Signed-off-by: Kulikov Vasiliy Signed-off-by: David S.
