Trigger port ingress rate limit engine to take effect
for all the priority queues according to priority
ingress limit control.
Note: Any write to this register will trigger port
ingress rate limit engine to take effect
for all the priority queues according to
priority ingress limit control. For the port
priority 0 - 3 ingress rate limit control to
take effect, Bit[7] of in Register 186,
202, 218, 234 and 250 for Ports 1, 2, 3,
4 and 5, respectively will need to set last
after configured Bits[6:0] of Port Ingress
Limit Control 1 - 4 registers.
