Public bug reported:
With hierarchical port binding, when vm migrating across ToR switch, in the
first step, vm port plug in br-int on new host,
ovs agent get port details by calling get_devices_details_list, but the bottom
vlan segment is old before port hostid is updated and bottom vlan segment is
reallocated. Thus, ovs agent will add wrong network-related flows in ovs
bridges.
