From b6c871e5875798e5ed3744c725622dcd3c92be92 Mon Sep 17 00:00:00 2001 From: Erez Shitrit Date: Mon, 12 Jun 2017 10:45:21 +0300 Subject: [PATCH] IB/ipoib: Let lower driver handle get_stats64 call 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.
