Title:
  ml2 hierarchical port binding cause binding loop

Status in neutron:
  Fix Released

Bug description:
  Related to: Bug #1745572

  The binding loop still exists due to the mistaken comparison as below.

  https://pastebin.com/RRFX8YfG

  The value 1 refers to the segmentation_id of a "segment" object (e.g., vxlan vni, vlan tag).
  The value 2 refers to the uuid of a "segment" object, which will be persisted as ml2_port_binding_levels.segment_id after the binding process.
