ip6_input.c, in6.h:
* Add netinet6-specific mbuf flag M_RTALERT_MLD, shadowing M_PROTO6.
* Always set this flag if HBH Router Alert option is present for MLD,
even when not forwarding.
icmp6.c:
* In icmp6_input(), spell m->m_pkthdr.rcvif as ifp to be consistent.
* Use scope ID for verifying input. Do not apply SSM filters here, no inpcb.
* Check for M_RTALERT_MLD when validating MLD traffic, as we can't see
IPv6 hop options outside of ip6_input().
in6_mcast.c:
* Use KAME scope/zone ID in in6_multi.
* Update net.inet6.ip6.mcast.filters implementation to use scope IDs
for comparisons.
* Fix scope ID treatment in multicast socket option processing.
Scope IDs passed in from userland will be ignored as other less
ambiguous APIs exist for specifying the link.
* Tighten userland input checks in IPv6 SSM delta and full-state ops.
* Source filter embedded scope IDs need to be revisited, for now
just clear them and ignore them on input.
* Adapt KAME behaviour of looking up the scope ID in the default zone
for multicast leaves, when the interface is ambiguous.
mld6.c:
* Tighten origin checks on MLD traffic as per RFC3810 Section 6.2:
* ip6_src MAY be the unspecified address for MLDv1 reports.
* ip6_src MAY have link-local address scope for MLDv1 reports,
MLDv1 queries, and MLDv2 queries.
* Perform address field validation *before* accepting queries.
* Use KAME scope/zone ID in query/report processing.
* Break const correctness for mld_v1_input_report(), mld_v1_input_query()
as we temporarily modify the input mbuf chain.
* Clear the scope ID before handoff to userland MLD daemon.
* Fix MLDv1 old querier present timer processing.
With the protocol defaults, hosts should revert to MLDv2 after 260s.
* Add net.inet6.mld.v1enable sysctl, default to on.
ifmcstat.c:
* Use sysctl by default; -K requests kvm(3) if so compiled.
mld.4:
* Connect man page to build.
Tested using PCS.
IPv4 stack.
Diffs are minimized against p4.
PCS has been used for some protocol verification, more widespread
testing of recorded sources in Group-and-Source queries is needed.
sizeof(struct igmpstat) has changed.
__FreeBSD_version is bumped to 800070.
* Retire the old 'ifmcstat <kernel>' usage.
* Print AF_LINK records even if run against KVM.
This makes the KVM backend consistent with the sysctl backend.
* Suppress printing of link-layer group records by default.
* Add a -v switch to allow link-layer groups to be printed.
* If compiled without INET6 support, actually work.
* If compiled with INET6 support, print the scope ID of
all IPv6 addresses in both backends.
* Update man page.
* Update copyrights.
With this change, it is now reasonable to retire netstat -g.
Most of the SSM related gunk in this file will require later refactoring.
MFC after: 2 weeks
* Build with or without INET, INET6, or KVM features.
* When built without KVM, the sysctl-based getifmaddrs() function
is used as the back-end for the utility.
* Reflect the fact that FreeBSD now uses the in_multi refcount as
a true refcount.
* Style.
The utility may now be run without super-user privilege, albeit with
a less detailed display, equivalent to that of the soon-to-be-retired
netstat -g host-mode output.

Possibly merge or split with netstat -g.

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.
