This is so cool! A couple questions:

1) I have lost track: what drivers now incorporate FQ-CoDel?

2) How can we talk about this in OpenWrt (and elsewhere...)?
	- Is it correct/reasonable/sensible to say that the fq_codel wifi drivers are "good" while the others are "not-so-good"
	- Does the presence of a chip/driver from 1) above indicate a more desirable device?
	- Or is it more nuanced?

Thanks.

Rich

For just the FQ-codel in driver support, yeah, I think it's fair to say
that it's unambiguously "better".

I am hoping I can finally retire my ath9k and ath10k chips by next
christmas. Apparently amd is leveraging the mediatek MT7921K chip.
