Well, for now... I'd expect the delta to break eventually...

Excellent. I'd *really* like to get some testers doing ingress shaping
at above 60-80mbits, which seems to be a brick wall we've hit on
the ar71xx and octeon, on other platforms like the arm and x86.

A tool we use a lot is netperf-wrapper.

I went to sleep pre BBrc1. I woke up, and everything was in github.

It's still not clear to me how I'd build cero from frozen BB sources,
rather than the evolving github packages.

Yes, SQM by itself doesn't mean enough.
