Hajimu UMEMOTO 3384154590 Sync with recent KAME.
This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.

TODO:
  - The definitions of SADB_* in sys/net/pfkeyv2.h are still different
    from RFC2407/IANA assignment because of binary compatibility
    issue.  It should be fixed under 5-CURRENT.
  - ip6po_m member of struct ip6_pktopts is no longer used.  But, it
    is still there because of binary compatibility issue.  It should
    be removed under 5-CURRENT.

.Op Fl dr
.Ar intface

.Nm
sends an IPv6 multicast listener discovery (MLD) query packet toward
the specified multicast address,
.Ar maddr ,
toward interface
.Ar intface .
If you omit
.Ar maddr ,
linklocal all nodes multicast address(ff02::1) is used.

After sending a query,
.Nm
waits for replies for at most 10 seconds.
If a reply is returned,
.Nm
prints it with its type and then waits for another reply.
