By design for this card, when doing ingress shaping. The input 
counters are retrieved from the input queue counters in the PXF 
rather than from the MAC chip.

Depends on the card. If you do input policing on this port or a WS-X 
port you will see the port counters show the actual rate of packets 
being received.
