Yes, I did finally. What threw me off was that that 
TCP_ECN_create_request() were the value if checked as a boolean was 
inlined in the include file. I've missed that. Thanks for the tip.

At any rate, it means that "noecn" is not a good route option feature, 
since it is not boolean. I plan to handle those in the next patch set, 
if the current one is accepted.

Thanks,
Gilad
