Seriously, comparing sch_fq against fq_pie or fq_codel or cake is quite
strange.
sch_fq has no CoDel part, it doesn't drop packets, unless you hit some
limit.
First intent for fq was for hosts, to implement TCP pacing at low cost.
Maybe you need an hybrid, and this is very possible to do that.
I did recently one change in sch_fq. where non local flows can be hashed
in a stochastic way. You could eventually add CoDel capability to such
flows.
