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?
