Hope so. I look forward to testing that build soon - today, even,
maybe, if I get unburied enough from christmas stuff.

The QCA folk have made noises about how to go about airtime fairness
there. I really don't know how it will work, but there seemed to be a
lot of enthusiasm in the room at the talk.

 I am hoping merely that the intermediate queues implementation (and
thus, fq_codel) works with my older ath10k hardware at some point.

Not clear to me if the ubntlite is capable of the "right thing", in
particular, or what ath10k hardware enables it or not. When I last
tried it I was at 100s of ms of added latency on that ath10k in that

Well, I have some hope for the mt76, one day (already intermediate
queue enabled), and we've looked over quite a few wifi chipsets.
Marvell, perhaps. Quantenna appears impossible with the state of the
firmware today. To me, up first would be a working intermediate queues
implementation for, say, a few wifi chipsets used in clients like the
c.h.i.p and pi3.

I *dream* of finding an android chipset worth hacking on.
