From 5fe31deffa097795aed7ab276c90287823d26497 Mon Sep 17 00:00:00 2001 From: Ajit Khaparde Date: Wed, 7 Oct 2009 02:42:23 +0000 Subject: [PATCH] e1000: 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: Ajit Khaparde Signed-off-by: David S.
