Yes, with the mention that not all checks for 8021q uppers may be in place properly today. But we are in a better position of adding those checks now, since we have a good place to start in dsa_slave_netdevice_event. If you find scenarios that should be rejected when this flag is set, but aren't, let me know and we'll fix that. Nonetheless, if you go this route, then yes, you should set that flag.
