By default CN88XX BGX accepts all incoming multicast and broadcast
packets and filtering is disabled. The nic driver doesn't provide
an ability to change such behaviour.

This series is to implement DMAC filtering management for CN88XX
nic driver allowing user to enable/disable filtering and configure
specific MAC addresses to filter traffic.

This doesn't even compile:
