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

15 * NOT follow the spec for VLANs, but may be useful for doing very
