In case of trunk wiring os-vif is responsible for creating and deleting the trunk bridge (see [1] and [2]). It can happen that Neutron can't set the metadata on the bridge by adding i.e. bridge_name field the external_ids. In such case, when the trunk is deleted before all these operations were finished in Neutron, the clean-up of patches linking br-int and the trunk bridge will never happen. This patch adds the bridge_name field to external_ids in case it is a trunk_bridge to avoid such situation. Code documentation patch on Neutron side: [3].
