This version does indeed work against net-next. I managed to break
myself because I'd been fiddling with flows 32 in some cases, and my
returns ENOTSUPP for that which sqm doesn't catch... and ohhh....
boy... htb with a 1000 packet fifo buffer fallback... SUCKS! :)
As for profiling, once again I found myself distracted by the ecn
debate. Fitting ecn 500 flows through a 100mbit bottleneck results in
1300 packets outstanding
26 flows that can't start (presumably due to ecn fall back), and
without ecn, 450 packets outstanding 3 flows that can't start.
