NAME
       udaddy -	RDMA CM	datagram setup and simple ping-pong test.

SYNOPSIS
       udaddy [-s server_address] [-b bind_address] [-c	connections]
		 [-C message_count] [-S	message_size] [-p port_space]
       udaddy -s server_address	[-b bind_address] [-c connections]
		 [-C message_count] [-S	message_size] [-t tos] [-p port_space]

DESCRIPTION
       Establishes  a  set of unreliable RDMA datagram communication paths be-
       tween two nodes using the librdmacm, optionally transfers datagrams be-
       tween the nodes,	then tears down	the communication.

OPTIONS
       -s server_address
	      The  network  name  or IP	address	of the server system listening
	      for communication.  The used name	or address must	route over  an
	      RDMA device.  This option	must be	specified by the client.

       -b bind_address
	      The  local  network  address to bind to.	To bind	to any address
	      with IPv6	use -b ::0 .

       -c connections
	      The number of  communication  paths  to  establish  between  the
	      client and server.  The test uses	unreliable datagram communica-
	      tion, so no actual connections are formed.  (default 1)

       -C message_count
	      The number of messages to	transfer over each  connection.	  (de-
	      fault 10)

       -S message_size
	      The size of each message transferred, in bytes.  This value must
	      be smaller than the MTU of the underlying	RDMA transport,	or  an
	      error will occur.	 (default 100)

       -t tos Indicates	 the type of service used for the communication.  Type
	      of service is implementation dependent based on subnet  configu-
	      ration.

       -p port_space
	      The port space of	the datagram communication.  May be either the
	      RDMA UDP	(0x0111)  or  IPoIB  (0x0002)  port  space.   (default
	      RDMA_PS_UDP)

NOTES
       Basic  usage  is	to start udaddy	on a server system, then run udaddy -s
       server_name on a	client system.

       Because this test maps RDMA resources to	userspace, users  must	ensure
       that they have available	system resources and permissions.  See the li-
       bibverbs	README file for	additional details.
