  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.
  19 *
  20 *  Must be invoked with rcu_read_lock (ie preempt disabled)
  21 *  or with RTNL.
