To clarify, the Windows IB CM and Linux IB CM should interoperate fine.  Their
interfaces may differ, but the supported CM protocol should match.

for IB CM REQ messages, along with service ID formats.  An application on
Windows can communicate with an application on Linux that's using the RDMA CM if
it uses the correct service ID and CM REQ formats.
