Bug Fixes

• The independent ovn plugin package(pythonN-networking-ovn) is no longer required. The package is no longer available since Ussuri, and all codes are now included in the base neutron package.

• Bug #1987460: Previously the neutron::agents::ml2::mlnx class causes duplicate resources when used with the neutron::agents::dhcp class or the neutron::agents::l3 class. Now it is possible to workaround the error by implementing the following mitigation.

  • Include the neutron::agents::ml2::mlnx class AFTER the neutron::agents::dhcp class or the neutron::agents::l3

  • Set the interface_driver parameter and the dhcp_broadcast_reply parameter consistently.
