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. + +Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk> +Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com> +--- + diff --git a/package/kernel/mac80211/patches/345-ath9k-Turn-ath_txq_lock-unlock-into-static-inlines.patch b/package/kernel/mac80211/patches/345-ath9k-Turn-ath_txq_lock-unlock-into-static-inlines.patch new file mode 100644 index 0000000000..7fe2c78037 --- /dev/null +++ b/package/kernel/mac80211/patches/345-ath9k-Turn-ath_txq_lock-unlock-into-static-inlines.patch @@ -0,0 +1,62 @@ +From: =?UTF-8?q?Toke=20H=C3=B8iland-J=C3=B8rgensen?= <toke@toke.dk> +Date: Mon, 5 Dec 2016 13:27:38 +0200 +Subject: [PATCH] ath9k: Turn ath_txq_lock/unlock() into static inlines. +MIME-Version: 1.0 +Content-Type: text/plain;
