ee037f26bc Implement an option to administratively disable the negotiation of
IPv6 on an sppp interface.  In an IPv6-enabled kernel, every IPv6
interface automatically gets an IPv6 address assigned (and IPv6
multicast packets sent at initialization time).  For sppp links where
we know our remote peer wouldn't support IPv6 at all, there's no point
in attempting to negotiate IPV6CP (or to even dial out for an IPv6
packet at all for dial-on-demand interfaces).

I wish there were a more generic way to administratively disable IPv6
on an interface instead.  ume told me there isn't.

While i was at it, converted both, enable_vj and enable_ipv6 into flag
bits in struct sppp (enable_vj used to be an int of its own).

47d6b4a644 Fix my breakage to the low-level hardware sync drivers brought by the
inclusion of VJ compression into sppp.

Now, instead of the need to include this and that and everything plus
the kitchensink in each of those drivers, struct sppp uses struct
slcompress as an opaque structure only referenced by a pointer.  The
actual structure is then malloced at initialization time.

While i was at it, also fixed a bug where received VJ packets would only
be recognized if INET6 was defined.

5450aa1239 Implement timestamps so i4b/driver/i4b_isppp.c can derive the idle
time from the PPP packets sent.  This effectively merges rev 1.2 of
the old i4b_ispppsubr.c, with the exception that i eventually ended up
in debugging and fixing it so the idle time is now really
detected. ;-)  (The version in i4b simply doesn't work right since it
still accounts for incoming LCP echo packets which it is supposed to
ignore for idle time considerations...)

39cb697c8c Break out the relevant fields from struct sppp into a struct
sppp_parms that are needed for the SPPPIO[GS]DEFS ioctl commands.
This allows it to keep struct sppp inside #ifdef _KERNEL (where it
belongs), and prevents userland programs that wish to include
<net/if_sppp.h> from including the earth, the hell, and the universe
before the are able to resolve all the kernel-internal stuff that's in
struct sppp.

1a5d6f5e0b Implement VJ header compression for sppp.
This is the logical merge of rev 1.32 of i4b's old if_spppsubr.c (which
was based on PR misc/11767), plus (i4b) rev 1.6 of i4b's if_ispppsubr.c,
albeit with numerous stylistic and cosmetic changes.

10f461e8cb Fix some pseudo-enumeration constants in the IPv6 implementation so
they are unique and thus actually usable as flagbits.  I wonder how
it even worked so far...

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.

664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

da3b4fb7ee rganize the various modes (CISCO/AUTO/DEMAND/LEASED) a little bit better,
centralize the code.

Remember to call TLF/TLS on the hardware in CISCO mode.

00081cc989 Major overhaul of the SyncPPP layer. Basically, this comprises now a
full implementation of the sate machine as described in RFC1661, and
provides support for plugging in various control protocols.  I needed
this to provide PPP support for the BISDN project (right now).

Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer.  This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events).  Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles.  Please report if i broke
something in the existing drivers.

For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.
