       ucmatose - RDMA CM connection and simple ping-pong test.


       ucmatose [-s server_address] [-b bind_address] [-c connections]
                 [-C message_count] [-S message_size]
       ucmatose -s server_address [-b bind_address] [-c connections]
                 [-C message_count] [-S message_size] [-t tos]


       Establishes  a  set  of  reliable  RDMA connections between two nodes using the librdmacm,
       optionally transfers data between the nodes, then disconnects.


       -s server_address
              The network name or IP address of the server system listening for connections.  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 connections to establish between the client and server.  (default 1)

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

       -S message_size
              The size of each message transferred, in bytes.  (default 100)

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

       -m     Tests  event  channel  migration.   Migrates  all  communication  identifiers  to a
              different event channel for disconnect events.


       Basic usage is to start ucmatose on a server system, then run ucmatose -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
