Description
Default
TAG_VLAN_MASK_0[8:0].
Tag VLAN 0 output port mask The mask is valid only if MII
register 13.3 TAG_VLAN_EN is logic high and VID index is
4’b0000.
When IP178C receives a packet, it examines the VID index to
choose a tag VLAN mask and forwards the packets according
the MAC address table and the mask.
