Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/neutron" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Add port dns_domain processing logic

    This patchset adds logic to the ML2 DNS integration extension to process
    a new dns_domain attribute associated to ports.

    This patchset belongs to a series that adds dns_domain attribute
    functionality to ports.

    DocImpact: Ports have a new dns_domain attribute, that takes precedence
               over networks dns_domain when published to an external DNS
               service.

    APIImpact: Users can now specify a dns_domain attribute in port POST and
               PUT operations.
