[Make-wifi-fast] Does mac80211 use fq_codel

Hi,

I was wondering if mac80211 currently uses fq_codel in LEDE using
intermediate software queues.

Thank you,
Noah Causin

Depends on your driver: If you're using ath10k it does (I think). If
you're using ath9k, there's a patch in nbd's staging tree. No other
drivers use the intermediate queues that I'm aware of.

If you have a very recent patch (I think nbd's staging tree contains
it) ath10k will not support it unless you have a firmware capable of
peer-flow-control (not sure if it's publicly available yet). Not even
sure what FW is used in LEDE/OpenWRT now.

There's mt76 but I'm not sure if it's available in OpenWRT/LEDE (and
if so on which branch/repo).

Thank you both for the information.

I was wondering.  Would this commit for LEDE disable the fq portion of 
fq_codel in mac80211?

Yes. We have seen some performance problems with it enabled, so it is disabled until those are worked out.
