      7  * The TH3 power test test excercises the WCS power scenario
      8  * streaming MPLS/IPv6 packets on all ports at maximum rate. All ports are
      9  * configured in MAC/PHY/EXT loopback mode and each port is paired with a same speed
     10  * port. The test calculates the number of packets needed to saturate the ports
     11  * and send the packets from the CPU to each port pairs initially.
     12  * Then the packets are switched between the port pairs indefinitely. Once
     13  * the traffic reaches steady state, rate calculation is done by dividing the
     14  * transmit packet count changes and transmit byte count changes over a
     15  * programmable interval. The rates are checked against expected rates based on
     16  * port configuration and oversubscription ratio. Finally, packet integrity
     17  * check is achieved by redirecting the packets back to the CPU and compared
     18  * against expected packets.
     19  *
     20  * Configuration parameters passed from CLI:
