+Subject: [PATCH] wifi: mac80211: fix qos on mesh interfaces
+
+When ieee80211_select_queue is called for mesh, the sta pointer is usually
+NULL, since the nexthop is looked up much later in the tx path.
+Explicitly check for unicast address in that case in order to make qos work
+again.
+
+Fixes: 50e2ab392919 ("wifi: mac80211: fix queue selection for mesh/OCB interfaces")
