       ibv_uc_pingpong [-p port] [-d device] [-i ib port] [-s size] [-m	 size]
       [-r rx depth] [-n iters]	[-l sl]	[-e] [-g gid index]

BUGS
       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 sys-
       tems.
