       rping - RDMA CM connection and RDMA ping-pong test.


       rping -s [-v] [-V] [-d] [-P] [-a address] [-p port]
                 [-C message_count] [-S message_size]
       rping -c [-v] [-V] [-d] [-I address] -a address [-p port]
                 [-C message_count] [-S message_size]


       Establishes  a  reliable RDMA connection between two nodes using the librdmacm, optionally
       performs RDMA transfers between the nodes, then disconnects.


       -s     Run as the server.

       -c     Run as the client.

       -a address
              On the server, specifies the network address to bind the connection to.  To bind to
              any  address with IPv6 use -a ::0 .  On the client, specifies the server address to
              connect to.

       -I address
              The address to bind to as the source IP address to use. This is useful if you  have
              multiple addresses on the same network or complex routing.

       -p     Port number for listening server.

       -v     Display ping data.

       -V     Validate ping data.

       -d     Display debug information.

       -C message_count
              The number of messages to transfer over each connection.  (default infinite)

       -S message_size
              The size of each message transferred, in bytes.  (default 100)

       -P     Run  the  server in persistent mode.  This allows multiple rping clients to connect
              to a single server instance. The server will run until killed.


       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
