Title:
[L2] current binding port get type errors
Status in neutron:
Fix Released
Bug description:
get_binding_levels can return None if the binding host is None. But
the patch [1] did not handle such case. The code will raise a
TypeError.
[1] https://review.opendev.org/c/openstack/neutron/+/606827
Bug was first found in stable/rocky, but the master branch has same code.
