Subject: [infiniband] Add a "communication-managed reliable connection"
 protocol

SRP over Infiniband uses a protocol whereby data is sent via a
combination of the CM private data fields and the RC queue pair
itself.  This seems sufficiently generic that it's worth having
available as a separate protocol.
