-Subject: [PATCH] ath9k: Introduce airtime fairness scheduling between stations
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This reworks the ath9k driver to schedule transmissions to connected
-stations in a way that enforces airtime fairness between them. It
-accomplishes this by measuring the time spent transmitting to or
-receiving from a station at TX and RX completion, and accounting this to
-a per-station, per-QoS level airtime deficit. Then, an FQ-CoDel based
-deficit scheduler is employed at packet dequeue time, to control which
-station gets the next transmission opportunity.
-
-Airtime fairness can significantly improve the efficiency of the network
-when station rates vary. The following throughput values are from a
-simple three-station test scenario, where two stations operate at the
-highest HT20 rate, and one station at the lowest, and the scheduler is
-employed at the access point:
-
- Before / After
-Fast station 1: 19.17 / 25.09 Mbps
-Fast station 2: 19.83 / 25.21 Mbps
-Slow station: 2.58 / 1.77 Mbps
-Total: 41.58 / 52.07 Mbps
-
-The benefit of airtime fairness goes up the more stations are present.
-In a 30-station test with one station artificially limited to 1 Mbps,
-we have seen aggregate throughput go from 2.14 to 17.76 Mbps.

-Subject: [PATCH] ath9k: Turn ath_txq_lock/unlock() into static inlines.
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-These are one-line functions that just call spin_lock/unlock_bh(); turn
-them into static inlines to avoid the function call overhead.
