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