Sorry, that turns out not to be the case for NetBSD.  In Steve
Deering's design, software checks of link-level multicast addresses
aren't done , because multicast address level checks need to be done
at a higher-level protocol (IP) anyway.  At least that's how I
remember it.

Uh, NetBSD has *always* had IPmulticast support.  If you hadn't
noticed, this a NetBSD mailing list For technical discussion of
NetBSD's networking code.  Please keep responses on-topic and
technically accurate!

If someone at Tandem is forwarding this internally to an audience that's
not technically au-fait with BSD networking, maybe they should reconsider.
