Subject: IB/ipoib: Let lower driver handle get_stats64 call
Patch-mainline: v4.13-rc2
Git-commit: b6c871e5875798e5ed3744c725622dcd3c92be92
References: bsc#1046307 FATE#322941
The driver checks if the lower level driver supports get_stats, and if
so calls it to get the updated statistics, otherwise takes from the
current netdevice stats object.
