Cake. fq_codel on 8 classes of classification, integrated bandwidth
managment, and a single command line to configure.

tc qdisc add dev eth1 root cake bandwidth 80mbit diffserv

Some of the ideas are still problematic, but thanks to jonathon morton,
it's running code now. I hope the bandwidth shaping idea ends up lighter
weight than htb....
