This is a bug fix but targetted at net-next, and indeed it is quite invasive as it adds new core infrastructure and converts the generic vlan code over to using it. Unfortunately net-next is closed. So if you want this bug fixed in mainline you will have to come up with a less invasive fix, and resubmit this net-next approach when the net-next tree opens back up. Thank you.
