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] -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 connec‐
	      tion to.	On the client, specifies the server address to connect
	      to.

       -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.
