An evil flow is one that is consistently not responding to drops, and
occupying a vastly disproportionate amount of queue space compared to
the other flows.
The HHF qdisc has a concept like this in it, but what I have in mind
Somewhat related, we can make cake_drop be less cpu intensive and more
deterministic with a small cache of the top (say, 3) "offenders"
maintained at either dequeue or enqueue time.
(ideas based on pounding codel flat with iperf -u and watching it stay
pounded flat for a long period of time)
What will it take to vastly improve wifi for everyone?
