Reliable connected and unreliable datagram are not the same as TCP and UDP, respectively.  The QP provides reliable connected or unreliable datagram data transmission, but in the case of IB it is not tied to any upper-level wire protocol.  For iWARP, it could be TCP or SCTP.  Other hardware types might have yet other underlying protocols, or a protocol not defined in the IANA protocol list at all.

Is there any reason the protocol shouldn't be an input parameter to endpoint creation, and help define the SID?
