Title:
  VMs cannot access metadata when connected to a network with only IPv6
  subnets with the ML2/OVS and ML2/LB backends in the Neutron zuul gate

Status in neutron:
  Fix Released

Bug description:
  While fixing https://bugs.launchpad.net/neutron/+bug/2069482 "[OVN]
  VMs cannot access metadata when connected to a network with only IPv6
  subnets", a neutron-tempest-plugin test case was proposed to make sure
  in the CI system that VM's can access the metadata service over an
  IPv6 only network: https://review.opendev.org/c/openstack/neutron-
  tempest-plugin/+/925928. While the new test case succeeds with the
  ML2/OVN backend thanks to this fix
  https://review.opendev.org/c/openstack/neutron/+/922264, it also
  showed the following failure with the ML2/OVS and ML2/LB backends:

  curl: (28) Failed to connect to fe80::a9fe:a9fe port 80: Connection
  timed out

  Steps to reproduce:

  Recheck https://review.opendev.org/c/openstack/neutron-tempest-
  plugin/+/925928 and see the logs for the ML2/OVS and ML2/LB jobs

  
  How reproducible: 100%
