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 between two nodes using the librdmacm, optionally
transfers datagrams between 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.
-c connections
The number of communication paths to establish between
the client and server. The test uses unreliable data-
gram communication, so no actual connections are
formed. (default 1)
-C message_count
The number of messages to transfer over each connec-
tion. (default 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 communica-
tion. Type of service is implementation dependent
based on subnet configuration.
-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 libibverbs README file for additional
details.
