Looks pretty ok for me. Though while at it, instead of doing an explicit
cast for each access, I'd use typed pointers and do the cast only once.
It'd be more readable that way IMHO.

Makes sense. Also explains why it happens with IPv6 only too.

Yes. There's some other patches related to ipv6 scope id too. My
opinion is to find all the places where it's set and set it to zero
when it's not valid. So this is definitely the right thing to do.
