The CMA should perform the QP transitions on both sides.

The main difference between the SDP and other users of the CMA is that SDP
passes in the start of the SDP hello header, and owns setting any information
not related to the IP addressing, such as the SDP version, MaxAdverts, etc.  The
CMA will fill in the IP version, IP addresses, and local port.
