Message-Id: <20161019092457.15006-1-tklauser@distanz.ch>
Date: Wed, 19 Oct 2016 11:24:57 +0200
From: Tobias Klauser <tklauser@...tanz.ch>

Cc: netdev@...r.kernel.org, linuxppc-dev@...ts.ozlabs.org
Subject: [PATCH] net: fs_enet: Use net_device_stats from struct net_device
Instead of using a private copy of struct net_device_stats in struct
fs_enet_private, use stats from struct net_device. Also remove the now
unnecessary .ndo_get_stats function.
