Message-Id: <1399880605-28772-3-git-send-email-amirv@mellanox.com> Date: Mon, 12 May 2014 10:43:18 +0300 From: Amir Vadai <amirv@...lanox.com> To: "David S. Miller" <davem@...emloft.net> Cc: netdev@...r.kernel.org, Amir Vadai <amirv@...lanox.com>, Yevgeny Petrilin <yevgenyp@...lanox.com>, Or Gerlitz <ogerlitz@...lanox.com>, Ido Shamay <idos@...lanox.com> Subject: [PATCH net-next 2/9] net/mlx4_en: User prio mapping gets corrupted when changing number of channels From: Ido Shamay <idos@...lanox.com> When using ethtool set_channels, mlx4_en_setup_tc is always called, even when it was not configured. Fixed code to call mlx4_en_setup_tc() only if needed.
