The earlier email was for hidden devices; the intent there is to hide certain devices (e.g., switch control netdevs) from user dumps by default. Adding an attribute at create time such as IFF_INVISIBLE for such devices would be a follow on to this set - but leveraging the same sysctl and sysfs bypasses.
