mac80211: implement fair queueing per txq
mac80211's software queues were designed to work very closely with device tx queues. They are required to make use of 802.11 packet aggregation easily and efficiently. Due to the way 802.11 aggregation is designed it only makes sense to keep fair queuing as close to hardware as possible to reduce induced latency and inertia and provide the best flow responsiveness. This change doesn't translate directly to immediate and significant gains. End result depends on driver's induced latency. Best results can be achieved if driver keeps its own tx queue/fifo fill level to a minimum. Signed-off-by:Michal Kazior <michal.kazior@tieto.com> Signed-off-by:
