That's a request for the feature. I have been digging into the
underlying QoS code on a few commercial products,
and documenting where fq-codel was on the wikipedia page:
https://en.wikipedia.org/wiki/FQ-CoDel - I need to add there's
another common thing "out there" - eero and google call sqm 'optimize
for conferencing and gaming".

I've found doc at least for a few more implementations - notably
riverbed and sophos.

cake, btw, has been part of riverbed's branch routers for a really
long time. a support rep told me he estimated about 40% usage.

and this got 170 upvotes yesterday:

One thing we need to do is adopt the right cc-by- license on the site.
:) Someone else did a wikipedia page for cake but it got
removed for copyright reasons.
