In ingress, the buffers are accounted at per PG basis and would indicate the number of the packets that has ingress this port
PG but still queued up in egress pipeline. However, there is no direct mapping between the PG and Queue.
Packet is assigned an internal priority on the ingress pipeline based on the queue to which it is destined. This Internal-priority to
Queue mapping has been modified and enhanced as follows for the device:
