Usage: There is only one PFR register. For each port there is an enable bit (ECR1 bit 6: IFE- Ingress filter
Enable) which determines whether the settings in PFR are applied to that port.

TK_MSK
Port trunk mask for trunking hash key
CPU sets up this table as follows:
1. Set all bits not in Trunk Groups to 1
2. Set all bits in the Trunk Group to 0
3. Pick one forwarding port per trunk group and turn the corresponding bit to 1 (Each Hash Key may have different
forwarding ports, the rule to pick forwarding ports is up to the CPU).
