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.
