IP is connectionless but has been implemented on top of connection
oriented link layers which may gateway to other connection oriented link
layers or non connection oriented link layers. I think it is analagous
to that.

I didn't think that IP was even being run in this case. Aren't we talking about an application level gateway? If the RDMA CM ran a protocol that ensured that data sent from the source reached the actual destination, then this would make more sense to me. But the protocol is coming from the client.

I just don't think that the RDMA CM should connect to a gateway under the assumption that a client is running a protocol that operates this way. If the source and destination were both running iWarp, then wouldn't a connection be established to the actual destination, and not a gateway?
