The whole point of the CMA is that the ULP can code to an
API that is independent of RDMA interconnect. The
CMA wire protocol can be documented to allow
non-Linux hosts to connect to a Linux box using 
the same protocol. There is no need to change the existing
IB CM protocol to accomplish this. All that is needed is
to document that CMA protocol (contained in the private data
field of the IB CM requests).
