Yes, this is an hold hack that was made because ebtables is
very feature-limited.

However, as I mentioned before I don't think there is anything
we can do here except audit all affected nft expressions and ip6tables
matches and add this check where needed.  ip6t_rpfilter.c comes to mind.

In any case your patch looks ok to me.
