- 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+
