This register counts the number of packets filtered at ingress due to Ingress Message Filtering. The packet will also be
counted as an error by the receiving MAC.
Note:
Port and GPIO registers share a common address space. Port registers are selected by the Bank Select
(BANK_SEL[2:0] in the 1588 Bank Port GPIO Select Register (1588_BANK_PORT_GPIO_SEL). The port
