The RDMA CM is only used on the local (active or client) side to obtain a path 
record, which is needed by the libibcm.  Using the librdmacm allows cmpost to 
get a path record given only the remote IP address or host name.

The connection is established using the IB CM through libibcm.

rdma_cm.h defines the kernel interface to the RDMA CM.  rdma_cma.h defines the 
userspace interface.

Can you verify that you have the latest version of rdma_cma.h?
