- *	The ADM5120 uses an internal matrix to determine which ports
- *	belong to which VLAN.
- *	The default generates a VLAN (and device) for each port
- *	(including MII port) and the CPU port is part of all of them.
- *
- *	Another example, one big switch and everything mapped to eth0:
- *	0x7f, 0x00, 0x00, 0x00, 0x00, 0x00
