[Cake] l4s thoughts

[Dave Taht]

whenever I get some time (and the right tcp patches) is fiddle with
two l4s approaches in fq_codel. The easy one is to leverage
ce_threshold,
accepting 1ms of queuing delay.

A better one, I think is to leverage the sparse flows optimization in
fq_codel to always mark when it's an old flow, and never mark when
it's new. That appears to be the most scalable, down to us or less.

Both ideas would take some work to do in cake, and I lack time and the
dctcp patches to try it.
