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?
