16.3.0
^^^^^^


Known Issues
************

* Even with the "igmp_snooping_enable" configuration option stating
  that traffic would not be flooded to unregistered VMs when this
  option was enabled, the ML2/OVN driver didn't follow that behavior.
  This has now been fixed and ML2/OVN will no longer flood traffic to
  unregistered VMs when this configuration option is set to True.


Bug Fixes
*********

* Fixed MAC learning issue when ovs offload enabled. OVS firewall
  reduce the usage of normal actions to reduce cpu utilization. This
  causing flood rule because there is no MAC learning on ingress
  traffic. While this ok for none offload case, when using ovs offload
  flood rule is not offloaded. This fix the MAC learning in the
  offload, so we avoid flood rule. #1897637
