-Subject: [PATCH] bcm63xx_enet: Fix sporadic kernel panic
-
-In ndo_stop functions, netdev_completed_queue() is called during forced
-tx reclaim, after netdev_reset_queue(). This may trigger kernel panic if
-there is any tx skb left.
-
-This patch moves netdev_reset_queue() to after tx reclaim, so BQL can
-complete successfully then reset.
