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

SYNOPSIS
       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]

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

OPTIONS
       -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.

NOTES
       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.
