13 Establishes a reliable RDMA connection between two nodes using the
14 librdmacm, optionally performs RDMA transfers between the nodes,
25 On the server, specifies the network address to bind the connection to.
26 On the client, specifies the server address to connect to.
29 Port number for listening server.
38 Display debug information.
41 The number of messages to transfer over each connection. (default infinite)
44 The size of each message transferred, in bytes. (default 100)
47 Run the server in persistent mode. This allows multiple rping clients
48 to connect to a single server instance. The server will run until killed.
50 Because this test maps RDMA resources to userspace, users must ensure
51 that they have available system resources and permissions. See the
52 libibverbs README file for additional details.
