From 1b85ee09aac2f32f24b8db72eb152089b92ace87 Mon Sep 17 00:00:00 2001 From: Wei Yang Date: Tue, 3 Dec 2013 10:04:10 +0800 Subject: net/mlx4_core: destroy workqueue when driver fails to register When driver registration fails, we need to clean up the resources allocated before. mlx4_core missed destroying the workqueue allocated. This patch destroys the workqueue when registration fails. Signed-off-by: Wei Yang Signed-off-by: David S.

The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.
