Subject: [RFCv2 0/3] mac80211: implement fq codel

Hi,

Most notable changes:
 * fixes (duh); fairness should work better now,
 * EWMA codel target based on estimated service
   time,
 * new tx scheduling helper with in-flight
   duration limiting (same idea Emmanuel
   had for iwlwifi),
 * added a few debugfs hooks.
 * ath10k proof-of-concept that uses the new tx
   scheduling (will post results in separate
   email)

The patch grew pretty big and I plan on splitting
it before next submission. Any suggestions?

The tx scheduling probably needs more work and
testing. I didn't evaluate how CPU intensive it is
nor how it influences things like peak throughput
(lab conditions et al) yet.

I've uploaded a branch for convenience:

  https://github.com/kazikcz/linux/tree/fqmac-rfc-v2

This is based on Kalle's ath tree.
