From mboxrd@z Thu Jan 1 00:00:00 1970 From: Leon Romanovsky Subject: [PATCH rdma-next] IB/ipoib: Let lower driver handle get_stats64 call Date: Mon, 12 Jun 2017 10:45:21 +0300 Message-ID: <20170612074521.15785-1-leon@kernel.org> Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Doug Ledford Cc: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Erez Shitrit List-Id: linux-rdma@vger.kernel.org From: Erez Shitrit 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.
