This looks great, could you by any chance confirm that the GUI
does allow to configure cake and that you can or can not set the
overhead for cake in the link layer adjustments (LLA) tab? (select cake
as link layer adjustment method, and put 42 into the overhead field and
report the output of “tc -d qdisc” before and after selecting cake as
LLA). @Toke: If that works, I think we can safely push these changes
into the openwrt repositories...
Here is the output. What I don't see is both ingress and egress ECN
markings even though I have selected this in the advanced configuration
under Queue Discipline.
Before changing LLA:
