Subject: Re: Per-CPU Queueing for QoS

I have been thinking we'd try to submit sch_cake to mainline on this
go-around. It's been out of tree for way too long.

I look forward to understanding your patches soon in the tbf case.

(I'm only responding because cake uses deficit, rather than a token
bucket, scheduler, and is not reliant on the tc filter infrastructure
for its queuing, and I'd love to have it handle multiple cpus better.
)
