Currently, we don't notify the switch at all when the PF administratively sets a new VLAN or MAC address. This causes the old addresses to remain valid on the switch table. Since the PF is overriding any configuration done directly by the VF, we choose to simply re-create the LPORT for the VF. This does mean that all rules for the VF will be dropped when we set something directly via the PF, but it prevents some weird issues where the MAC/VLAN table retains some stale configuration.
