Cool. Another idea for a test is a real torrent or 5 of a really big
well distributed file on one etherport, while a set of hosts do
normal-home like things on the other, with cake unlimited vs fq-codel,
and bandwidth limited for both. We don't have good numbers for cake at
line rate in a scenario where we can dump 2Gbit into 1 in the real
world.
