  I think you hit the nail on the head. Ideally we would have a unified
verbs API, and then a seperate generic connection manager. The verb API
is already similar between the two transports, the real question is how
do ULPs establish connections in a transport neutral manner. In my mind
forget the other stuff, focus on the real issue.
