Hi,

I'm catching up on FreeBSD email after a long hiatus.

That's because the ip_multicast_if() hack has been deprecated in 
-CURRENT for months now, because routed (and other multicast 
applications) really should be using the RFC 3678 APIs.

I'm pretty sure I already pointed people at patches for converting 
routed to use the updated multicast APIs much earlier in the year; 
please check the archives, or see here:
    http://people.freebsd.org/~bms/dump/routed.rfc3678.diff

I haven't tested or committed the routed patch due to a lack of user 
feedback, sadly -- which is regrettable, we all end up feeling the pain 
during a release cycle if issues aren't nipped in the bud there and then.

Marko: I would much prefer it if ip_multicast_if() is not reintroduced 
to 7-CURRENT.

kind regards,
BMS
