have a lot of uses.


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 ..
