From 7bfba0b0c15962265950ac0efe6bd4f42414db6d Mon Sep 17 00:00:00 2001 From: Kulikov Vasiliy Date: Mon, 5 Jul 2010 02:14:03 +0000 Subject: [PATCH] lance: 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.
