70057abf2d Deprecate the -l option in favour of more natural -W.
The compatibility glue is still provided.

(This change is not yet reflected in the manpage, nor
in usage().  This will be fixed at a later time today,
with the general manpage cleanup commit.)

785d213d3f - create an entry of IPV6CTL_STATS sysctl.
- fix the problem that netstat doesn't show raw6 and icmp6 pcblist.
- make netstat use sysctl to retreive stats of ipv6 and icmpv6
  instead of kread.

08442f8a82 Introduce numerous SMP friendly changes to the mbuf allocator. Namely,
introduce a modified allocation mechanism for mbufs and mbuf clusters; one
which can scale under SMP and which offers the possibility of resource
reclamation to be implemented in the future. Notable advantages:

 o Reduce contention for SMP by offering per-CPU pools and locks.
 o Better use of data cache due to per-CPU pools.
 o Much less code cache pollution due to excessively large allocation macros.
 o Framework for `grouping' objects from same page together so as to be able
   to possibly free wired-down pages back to the system if they are no longer
   needed by the network stacks.

 Additional things changed with this addition:

  - Moved some mbuf specific declarations and initializations from
    sys/conf/param.c into mbuf-specific code where they belong.
  - m_getclr() has been renamed to m_get_clrd() because the old name is really
    confusing. m_getclr() HAS been preserved though and is defined to the new
    name. No tree sweep has been done "to change the interface," as the old
    name will continue to be supported and is not depracated. The change was
    merely done because m_getclr() sounds too much like "m_get a cluster."
  - TEMPORARILY disabled mbtypes statistics displaying in netstat(1) and
    systat(1) (see TODO below).
  - Fixed systat(1) to display number of "free mbufs" based on new per-CPU
    stat structures.
  - Fixed netstat(1) to display new per-CPU stats based on sysctl-exported
    per-CPU stat structures. All infos are fetched via sysctl.

 TODO (in order of priority):

  - Re-enable mbtypes statistics in both netstat(1) and systat(1) after
    introducing an SMP friendly way to collect the mbtypes stats under the
    already introduced per-CPU locks (i.e. hopefully don't use atomic() - it
    seems too costly for a mere stat update, especially when other locks are
    already present).
  - Optionally have systat(1) display not only "total free mbufs" but also
    "total free mbufs per CPU pool."
  - Fix minor length-fetching issues in netstat(1) related to recently
    re-enabled option to read mbuf stats from a core file.
  - Move reference counters at least for mbuf clusters into an unused portion
    of the cluster itself, to save space and need to allocate a counter.
  - Look into introducing resource freeing possibly from a kproc.

cf5e44f88e First round of netstat(1) cleanup.
Removed the ambiguity in -s, -f, -p and -i flags handling.
Basically, there are four displays (except others):

1.  PCB display.
2.  Protocol statistics display. (-s)
3.  Interface statistics display. (-i)
4.  Per-interface protocol statistics display. (-i -s)

All of the above except 3) can be limited to a particular
protocol family (-f) or a single protocol (-p).

Some examples:

1.  netstat -f inet    -- show PCBs of all INET protocols
2.  netstat -p udp     -- show PCB of UDP protocol only (NEW!)
3.  netstat -s         -- show protocol statistics for all families
4.  netstat -s -f inet -- show INET protocols statistics
5.  netstat -s -p icmp -- show ICMP protocol statistics

This is a work in progress.  Manpage has been fixed slightly,
but is still incomplete.

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.

cc63cd5663 A couple of changes of mine that I've been using for a while:
route.c: look up the netname as-is first before the shifted name. this
         makes a big speed difference, as the lookups are generally local
	 DNS.  The shifted names can be very wrong (there is still guessing
	 and fudging involved) and usually go remote, taking a long time
	 to fail.  If you have the RFC reccomended netnames in your reverse
	 lookups, this is even faster still.
main.c:  dont do a sethostent(1) - this is causing the resolver to use a
	 VC (tcp) connection to the resolver, which has more overheads and
	 is slower than the default UDP case.  This once made sense when
	 everything was based on text host tables.
