+Subject: [PATCH] mac80211: unconditionally start new netdev queues with iTXQ
+ support
+
+When internal mac80211 TXQs aren't supported, netdev queues must
+always started out started even when driver queues are stopped
+while the interface is added. This is necessary because with the
+internal TXQ support netdev queues are never stopped and packet
+scheduling/dropping is done in mac80211.
+
+Cc: stable@vger.kernel.org # 4.9+
+Fixes: 80a83cfc434b1 ("mac80211: skip netdev queue control with software queuing")
