bufferbloat-beating customer shaping via LibreQoS

There's been a huge uptake in interest lately in doing better per
device and per customer shaping, especially for
ISPs, in the libreQoS.io project, which is leveraging the best ideas
bufferbloat project members have had over the
past decade (cake, bpf, xdp) to push an x86 middlebox well past the
10Gbit barrier, on sub-2k boxes, with really
good stats on backlogs, drops, and ecn marks. I've long primarily
tried to get fq_codel and cake running on the CPE (most recently
mikrotik), and that's been taking too long.

I have no idea to what extent members of this list have interest in
this, but if you know of a smaller ISP with bad bufferbloat,
please pass that link along? It's got ridiculously easier to set up as
a vm of late.

There is presently a design discussion going on over here:


And by mentioning it here, today, I'm mostly asking what other real
life use cases we should try to tackle? What backend tools should we
try to integrate with?
