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.
