Subject: [PATCH 4.4 04/38] net: bridge: add missing counters to ndo_get_stats64 callback

From: Heiner Kallweit <hkallweit1@...il.com>

[ Upstream commit 7a30ecc9237681bb125cbd30eee92bef7e86293d ]

In br_forward.c and br_input.c fields dev->stats.tx_dropped and
dev->stats.multicast are populated, but they are ignored in
ndo_get_stats64.
