Public bug reported: This scenario test neutron_tempest_plugin.scenario.test_trunk.TrunkTest.test_subport_connectivity is failing quite often in neutron-tempest-plugin-dvr-multinode-scenario-queens job. But it's not failing in same job run on rocky, stein or master branch. The difference between those jobs is that in queens we are still using iptables_hybrid fw driver and in newer versions we are using ovs based firewall.
