Comment 36 for bug 1815989

we figured out what was cause issue for the neutron openvswitch firewall driver yesterday.
rodolfo has propsoed the testing patch https://review.opendev.org/#/c/753314/ bugfix.
that should allow https://review.opendev.org/#/c/602432/20 to move forward and hopefully merge next week once the neutron patch is merged. the nova patch also requires https://review.opendev.org/#/c/751642/5 which should also be merged shortly.

once these are all merged on the master branch we can start the backport process.

the main code for the fix has been available for some time but there were a number of edgecases that had to be adressed. we started looking at these patches again about 2 weeks ago an i think
the main edgecaes have now been addressed.
