Octavia has received a couple of patches in master upstream during Rocky development cycle that are worthy of backporting to OSP13: https://review.openstack.org/#/c/540356/ https://review.openstack.org/#/c/547967/ https://review.openstack.org/#/c/557197/ https://review.openstack.org/#/c/546078 (look deeply into it and search for possible risks) These patches cannot be backported upstream to stable/queens, though.
Leaving https://review.openstack.org/#/c/546078 behind as we're getting closer to GA date. We may revisit it later.
