[Codel] [PATCHv4 0/5] mac80211: implement fq_codel

[Michal Kazior <michal.kazior@tieto.com>]

Hi,

This patchset disables qdiscs for drivers
using software queuing and performs fq_codel-like
dequeuing on txqs.

This is based on net-next/master
(035cd6ba53eff060760c4f4d11339fcc916a967c).

For anyone interested I've pushed tree with my
(now oldish) ath10k DQL RFC and a small fix I've
been testing:

   into separate patches [Avery]

v2:
 * fix invalid ptr deref
 * fix compilation for backports
