net: dsa: loop: Preparatory changes for 802.1Q data path
Florian Fainelli says:

====================
These patches are all meant to help pave the way for a 802.1Q data path
added to the mockup driver, making it more useful than just testing for
configuration. Sending those out now since there is no real need to
wait.
====================
