10/* Find a VLAN device by the MAC address of its Ethernet device, and
11 * it's VLAN ID. The default configuration is to have VLAN's scope
12 * to be box-wide, so the MAC will be ignored. The mac will only be
13 * looked at if we are configured to have a separate set of VLANs per
14 * each MAC addressable interface. Note that this latter option does
15 * NOT follow the spec for VLANs, but may be useful for doing very
16 * large quantities of VLAN MUX/DEMUX onto FrameRelay or ATM PVCs.
17 *
18 * Must be invoked with rcu_read_lock (ie preempt disabled)
19 * or with RTNL.
