I've completed the port and tested it yesterday, unfortunately it's
not useable in the real world as is. There is a strong bias against
non-ECN flows because their packets are simply dropped instead of
marked. At high load (50 ECN vs. 1 non-ECN flow) and a marking
probability of about 10% the non-ECN flow simply stalls.
I can send you the patch if you're interested ..

Regards
Patrick
