Title:
      IP allocation with Service Subnets

Status in openstack-manuals:
  New

Bug description:
  https://review.openstack.org/350613
  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.

      IP allocation with Service Subnets
      
      This changes the way that IPAM decides which subnets to use when
      assigning IPs to newly created ports. If the port has a defined
      device_owner, this is used to filter available subnets to choose
      from only those with a matching service_type or no service_type
      at all.
      
      If the given network has no service subnets, then the existing
      behaviour is used.
      
      A new IPAM exception is introduced to handle the following scenarios:
      1. A port is created with a device_owner and only non-matching service
         subnets exist.
      2. A port is created without a device owner, and no subnets exist
         without a service_type.
      
      With this patch, service subnets are now usable.
      
      Implements: blueprint service-subnets
      APIImpact: subnet-create and subnet-update with service_types
      DocImpact: IPs assigned to new ports will now come from a service subnet
      matching the port device_owner, if one exists.
