--- Comment #1 from Bjoern A. Zeeb <bz@FreeBSD.org> ---
It was never implemented for IPv4.
In IPv6 it's been done right from the start.

I think this patch (probably for FreeBSD 9) was supposed to improve the
situation for IPv4, but nobody ever did the performance evaluation as it's an
extra loop over all interface addresses:
