For duration (-D) latency tests, it is useful to have the average
transactions per second (tps) output.  So ib_*_lat now shows
average tps:

---------------------------------------------------------------------------------------
 #bytes        #iterations       t_avg[usec]    tps average
 2             1008430           2.97           168068.16
---------------------------------------------------------------------------------------
