/*  Find a VLAN device by the MAC address of its Ethernet device, and
 *  it's VLAN ID.  The default configuration is to have VLAN's scope
 *  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.
 *
 *  Must be invoked with rcu_read_lock (ie preempt disabled)
 *  or with RTNL.
