[Codel] [PATCH 0/2] mac80211: implement fq_codel

[Michal Kazior]

Hi,

I've cleaned up and removed the
txop-queue-limiting and scheduling from the patch
(compared to my last RFC). It's still to early for
the scheduling thing to go prime time.

The fair queuing on the other hand does seem to
work. In good RF conditions it seems to improve
things (e.g. multiple TCP streams converge into a
steady average). In bad RF conditions things look
same grim as before (but not worse).

I've done a few more experiments with naive DQL in
ath10k and some flent tests prove the fair queuing
in mac80211 works better than fq_codel qdisc as
far as wake_tx_queue drivers are concerned. I'll
be posting a separate thread after this.

This is based on mac80211-next/master
(0a87cadbb54e1595a5f64542adb4c63be914d290).
