ibv_ud_pingpong - simple InfiniBand UD transport test

       The  network  synchronization  between  client  and  server  instances  is  weak,  and  does  not prevent
       incompatible options from being used  on  the  two  instances.   The  method  used  for  retrieving  work
       completions is not strictly correct, and race conditions may cause failures on some systems.

       Run a simple ping-pong test over InfiniBand via the unreliable datagram (UD) transport.

-p, --port=PORT
              use TCP port PORT for initial synchronization (default 18515)

       -d, --ib-dev=DEVICE
              use IB device DEVICE (default first device found)

       -i, --ib-port=PORT
              use IB port PORT (default port 1)

       -s, --size=SIZE
              ping-pong messages of size SIZE (default 2048)

       -r, --rx-depth=DEPTH
              post DEPTH receives at a time (default 500)

       -n, --iters=ITERS
              perform ITERS message exchanges (default 1000)

       -l, --sl=SL
              send messages with service level SL (default 0)

       -e, --events
              sleep while waiting for work completion events (default is to poll for completions)

       -g, --gid-idx=GIDINDEX
              local port GIDINDEX-c, --chk
              validate received buffer
