Title:
  DHCP client/server ports incorrectly defined in constants file

Status in neutron:
  Fix Released

Bug description:
  The DHCP client and server port numbers are incorrectly defined in the
  constants file:

  DHCP_CLIENT_PORT = 67
  DHCP_RESPONSE_PORT = 68

  IANA defines these the opposite - 68 for the client and 67 for the
  server.

  Neutron uses them backwards, so will also need an update to work-
  around so a new release of neutron-lib doesn't break things.

  Also, other plugins seemed to have noticed and worked around this
  already, at least Dragonflow and Cisco have defined them correctly
  locally:
