I guess I missed the fact that OFED included this patch, rather than
relying on the other administratively configured schemes you
originally outlined. I was opining that nobody was complaining about
the administrative stuff.. but of course nobody complains, they don't
have to do it :(

A seperate IP for iWarp always seemed to me to be the way forward on
this. And I do mean seperate, as in TCP packets for this IP are never
sent into the net stack seperate :|
