net.core.default_qdisc defaults to FQ_CODEL but it's not enabled in kernel
Open, Needs More InfoPublic

Description

While reloading sysctl settings I noticed our net.core.default_qdisc setting defaults to FQ_CODEL, but it's unset in kernel config. At the same time I think it would be good to consider whether cake would be even better option.

sysctl: setting key "net.core.default_qdisc": No such file or directory

It's been awhile since I've looked into CAKE, but I remember it being promising. It looks like this is probably just a systemd default that we should either be overriding to what we are actually configured for or enabling FQ_CODEL.

Yes. FQ_CODEL is the Systemd default, but it falls back to pfifo_fast as it's not enabled in kernel.
