Re: [RFC v2] fq_codel : interval servo on hosts

fq_codel has a standing queue problem, based on the fact that when a

codel but not multi-queued fq_codel. So after we hit X high rate
flows, target can never be achieved, even straining mightily, and we
end up with a standing queue again.

Easily seen with like 150 bidirectional flows at 10 or 100Mbit.

(as queues go, it's still pretty good queue. And: I've fiddled with
various means of draining multi-queue behavior thus far, and they
ended up unstable/unfair)

No idea of what you mean by "codel.h resets".

Please use small mails, one idea by mail.
