Well, I rethink of what "interface-local" means.

It seems applications will join ff01::/16%eth0 instead of ff01::/16%lo.
If so, your original patch seems better.  My bad, sorry.

Would you update original one, with minor modification that defers
kfree_skb() after incrementing MIB, please?

If you think we should join ff01::{1,2} by default, you can send another
patch for it.  (BTW, why don't we join ff05::2, then? ;-))

Thanks.
