From 4b5e5b7ececc3265092712a4fef140cc6ef0d028 Mon Sep 17 00:00:00 2001 From: Alaa Hleihel Date: Sun, 29 Jan 2017 18:56:16 +0200 Subject: [PATCH] net/mlx4_core: Get num_tc using netdev_get_num_tc Avoid reading num_tc directly from struct net_device, but use the helper function netdev_get_num_tc. Fixes: bc6a4744b827 ("net/mlx4_en: num cores tx rings for every UP") Fixes: f5b6345ba8da ("net/mlx4_en: User prio mapping gets corrupted when changing number of channels") Signed-off-by: Alaa Hleihel Signed-off-by: Tariq Toukan Signed-off-by: David S.
