   3 Subject: [PATCH] mac80211: unconditionally start new netdev queues with iTXQ
   4  support
   5
   6 When internal mac80211 TXQs aren't supported, netdev queues must
   7 always started out started even when driver queues are stopped
   8 while the interface is added. This is necessary because with the
   9 internal TXQ support netdev queues are never stopped and packet
  10 scheduling/dropping is done in mac80211.
