Re: [PATCH v3 net-next] tcp: TCP Small Queues

Considering these two points, why TSQ over the Codel feedback
approach?

I dont think they compete. They are in fact complementary.

If you use codel/fq_codel + TSQ, you have both per flow limitation in
qdisc (TSQ) + sojourn time aware and multi flow aware feedback.

Makes sense. My conjecture is when using codel/fq_codel qdisc, the
need for TSQ will diminish. But as you said... good part of TSQ is it
limits per-flow queuing for any qdisc structure, even those not using
codel.
