[PATCH net-next V3 4/8] net/mlx4_core: Get num_tc using netdev_get_num_tc
From: Tariq Toukan <hidden>
Date: 2017-01-29 16:57:14
Subsystem:
mellanox ethernet driver (mlx4_en), mellanox mlx4 core vpi driver, networking drivers, the rest · Maintainers:
Tariq Toukan, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
From: Alaa Hleihel <redacted>
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")
