Description of problem: Fail to execute successfully the following test, after deploying RHOSP 9 HA (3 controllers, 2 compute): tempest.scenario.test_network_basic_ops.TestNetworkBasicOps.test_mtu_sized_frames Version-Release number of selected component (if applicable): openstack-neutron-8.1.2-8.el7ost.noarch openstack-neutron-bigswitch-agent-2015.3.8-1.el7ost.noarch openstack-neutron-bigswitch-lldp-2015.3.8-1.el7ost.noarch openstack-neutron-common-8.1.2-8.el7ost.noarch openstack-neutron-lbaas-8.0.0-1.el7ost.noarch openstack-neutron-metering-agent-8.1.2-8.el7ost.noarch openstack-neutron-ml2-8.1.2-8.el7ost.noarch openstack-neutron-openvswitch-8.1.2-8.el7ost.noarch How reproducible: 100% Steps to Reproduce: 1. Deploy RHOSP 9 HA 2.

Due to the way we deploy (OVB), the test failed for us. To make it pass, we had to set NeutronTenantMtu to 1450[1] before overcloud deployment. Note: for OSP >= 10 it's 'NeutronGlobalPhysnetMtu'.
