    Fix DHCP Port Creation on Service Subnets
    
    This changes the IPAM logic for service subnets to allow DHCP ports
    to be created on subnets of any service type, provided that the subnet
    has DHCP enabled.. This ensures that DHCP ports can still be created
    automatically on 'nova:compute' service subnets, for example.

Title:
  Service Subnets - DHCP port creation fails

Status in neutron:
  Fix Released

Bug description:
  Service Subnets[1] were added in Newton.

  The TL;DR is that a subnet can be created/updated with one or more
  service_types corresponding to a port device owner. If a subnet has
  one or more service_types, then only ports with a matching device
  owner can be created on the subnet.

  If a service subnet is created with dhcp enabled, automatic dhcp port
  creation fails, because the port device owner does not match the
  subnet's service_types.

  The port creation is re-attempted over and over, and the subnet
  remains without dhcp.

  Steps to recreate:

  NOTE: THIS REQUIRES INSTALLING OPENSTACKCLIENT FROM MASTER

  $ openstack network create test-net

  $ openstack subnet create test-subnet --subnet-range 10.1.0.0/24 \
    --service-type compute:nova --network test-net

  Then take a look in the q-svc logs.
