From: Raed Salem <raeds@xxxxxxxxxxxx>
Reads the hardware counters values and writes them to
the output index location in the user supplied array.
All counters values are represented as uint64_t types.
The read counter values in the array are defined according to the
configuration defined by user in the ibv_attach_counters_point_xxx
functions.
