Let's= assume we have a driver like ath9k or mt76, which tries to keep a
=E2=80=A6.

Well, there's going to be a BQL-like queue limit (but for = airtime) on
top, which = drivers can opt-in to if the hardware has too much queueing.


Very happy to = read this - I first talked to Dave Taht about the need for Time Queue = Limits more than 5 years ago!
