From 8dc43ddc9fe0af3a555af235a69a398c3eba2639 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Mon, 10 Mar 2014 13:12:23 +0100 Subject: [PATCH] net: eth: cpsw: Use net_device_stats from struct net_device Instead of using an own copy of struct net_device_stats in struct cpsw_priv, use stats from struct net_device. Also remove the thus unnecessary .ndo_get_stats function, as it just returns dev->stats, which is the default. Signed-off-by: Tobias Klauser Acked-by: Mugunthan V N Signed-off-by: David S.
