            Virtual machine interface is mapped to bridge domain based on the
            incoming 802.1Q vlan tag.

            This link attribute works along with vlan-tag-based-bridge-domain
            flag on the virtual-machine-interface

            1. if vlan-tag-based-bridge-domain is false
               All traffic (tagged/priority tagged/untagged) will be assigned to
               single bridge domain.

            2. if vlan-tag-based-bridge-domain is true
                Incoming traffic will be mapped to bridge domain based on vlan
                tag of the incoming traffic.
                Untagged/priority tagged traffic will be mapped to bridge domain
                with link attribute where vlan-tag = 0.
                Tagged traffic will be mapped to bridge domain with link
                attribute where vlan-tag = incoming vlan tag.
                For all tagged traffic where corresponding bridge domain mapping
                is missing will be dropped.

            In the current release, vlan-tag-based-bridge-domain will not be
            supported and single bridge domain will be linked to virtual machine
            interface. So all traffic (tagged/priority tagged/untagged) will be
            assigned to this single bridge domain.
