Ladies and gentlemen! Ryan Mounce has entered the room! Ryan
contributed the ack-filtering code in sch_cake several years ago. All
Hail Ryan! Cake ( https://lwn.net/Articles/758353/ )has been available
out of tree for linux for 5 years (with maintained backports all the
way back to linux 3.10) and it finally went upstream in linux 4.19.
Please note that as much as I like cake, the sqm scripts go back even
further (and also allow for configuring not just fq_codel but pie)

Well, I try to keep kicking em along. As noted in my previous message
we're seeing a couple ISPs in germany move on this (free.fr in france
adopted this stuff in 2012, everybody else is lagging somewhat :/)
It's only a few line of shell script hook into the negotiation phases
at this point. A days worth of work. Or less. And as for "correctly",
well, I keep hoping folk will leverage the sqm-scripts and/or cake -
when available. Aside from the fritzbox (which I know has fq_codel in
it), are there any other common home routers with a reasonably modern
linux or freebsd os in 'em?
Do you have any insight into the DHCP message?
who "owns" the end-user router in australia now?
anyway, my talk at linux.conf.au (and blatant plug #2) is reviewed now
great to see you here, ryan,
