From: Vladimir Oltean <vladimir.olt...@nxp.com>
This is for the "no extraction IRQ" workaround, where the DSA master on
LS1028A (enetc) serves as a de-facto irqchip.
It needs to be promiscuous so that it will never drop a PTP frame (sent
to the 01-80-c2-00-00-0e multicast MAC address), otherwise the tagger
will get confused about which Ethernet PTP frame corresponds to which
PTP frame over the MMIO registers.
