Hello, In Icehouse was introduced new column vif_details and removed cap_port_filter. During db migration data in cap_port_filter column are lost and after upgrade the vif_details column is legally empty. This leads to tempest tests failure when checking port_filter[1]. What would be the impact of running neutron-server without information about port_filter in vif_details? Should neutron-server check this on startup and according vif_type and mechanism_drivers set the port_filter? Thanks for explanation.
