Subject: wifi: mac80211: fix qos on mesh interfaces
From: Felix Fietkau <nbd@xxxxxxxx>
commit 4e348c6c6e23491ae6eb5e077848a42d0562339c upstream.
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.
