--- Comment #4 from Mark Johnston <markj@FreeBSD.org> ---
We define struct ip as having an alignment of 2, so it feels wrong to try and
handle the case where it has odd alignment. There may well be other code paths
where we (or the compiler) is making assumptions about header alignment, and we
have no good way to test.
So, since this issue hasn't really gotten attention in the 10+ years since it
was submitted, I'm going to go ahead and close this.
