Subject: mac80211: unconditionally start new netdev queues with iTXQ support
From: Johannes Berg <johannes.berg@intel.com>
commit 7d65f82954dadbbe7b6e1aec7e07ad17bc6d958b upstream.
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.
