/* Find a VLAN device by the MAC address of its Ethernet device, and

* to be box-wide, so the MAC will be ignored. The mac will only be
* looked at if we are configured to have a separate set of VLANs per
* each MAC addressable interface. Note that this latter option does
* NOT follow the spec for VLANs, but may be useful for doing very
* large quantities of VLAN MUX/DEMUX onto FrameRelay or ATM PVCs.
