13 * it's VLAN ID. The default configuration is to have VLAN's scope

14 * to be box-wide, so the MAC will be ignored. The mac will only be

15 * looked at if we are configured to have a separate set of VLANs per

16 * each MAC addressable interface. Note that this latter option does

17 * NOT follow the spec for VLANs, but may be useful for doing very

18 * large quantities of VLAN MUX/DEMUX onto FrameRelay or ATM PVCs.
