rdma_get_devices - Get a list of RDMA devices currently available.

       num_devices If non-NULL, set to the number of devices returned.

       Return  a  NULL-terminated  array  of  opened  RDMA  devices.   Callers  can use this routine to allocate
       resources on specific RDMA devices that will be shared across multiple rdma_cm_id's.

       rdma_get_devices - Get a list of RDMA devices currently available.

       The  returned  array  must  be  released  by  calling rdma_free_devices.  Devices remain opened while the
       librdmacm is loaded.

       Returns an array of available RDMA devices, or NULL if the request fails.  On failure, errno will be  set
       to indicate the failure reason.
