path MTU SIZE (default 1024)
-r, --rx-depth=DEPTH
post DEPTH receives at a time (default 1000)
-n, --iters=ITERS
perform ITERS message exchanges (default 1000)
-l, --sl=SL
use SL as the service level value of the QP (default 0)
-e, --events

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.
