Description (partial)

Symptom:
FP rules in BCM TD2 switch to prioritise some traffic like VLAN4047 are not working. All the traffic goes to queue 7 in BCM switch for traffic from CPU. While traffic from Customer facing ports goes to queue 0.

Some of the traffic also lands on queue 9 of fabric port.

Conditions:
Adding FP rules for Priority traffic in TD2 Switch doesn't hit. This is due to presence of default rules in TD2 which takes precedence over required rules.
