Rdma cm communication server test program
rdma_xserver [-p port] [-c comm_type]
Uses the librdmacm to establish various forms of communication and exchange data.
-p port
Changes the port number that the server listens on. By default the server listens on port 7471.
-c communication type
Specifies the type of communication established with the client program. 'r' results in using a reliable-connected QP (the default). 'x' uses extended reliable-connected XRC QPs.
Basic usage is to start rdma_xserver, then connect to the server using the rdma_xclient program.
Because this test maps RDMA resources to userspace, users must ensure that they have available system resources and permissions. See the libibverbs README file for additional details.
