64e41ba7c8 Increase the size of the route reference count from 15 bits to 31 bits.
This doesn't change the size or alignment of the structure on either i386
or Alpha, and thus should be binary-compatible (modulo problems with old
applications and routes with more than 2^15 references).

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

477180fbc8 Use the new if_multiaddrs list for multicast addresses rather than the
previous hackery involving struct in_ifaddr and arpcom.  Get rid of the
abominable multi_kludge.  Update all network interfaces to use the
new machanism.  Distressingly few Ethernet drivers program the multicast
filter properly (assuming the hardware has one, which it usually does).

9f9b3dc4ae Add three new route flags to help determine what sort of address
the destination represents.  For IP:

- Iff it is a host route, RTF_LOCAL and RTF_BROADCAST indicate local
  (belongs to this host) and broadcast addresses, respectively.

- For all routes, RTF_MULTICAST is set if the destination is multicast.

The RTF_BROADCAST flag is used by ip_output() to eliminate a call to
in_broadcast() in a common case; this gives about 1% in our packet-generation
experiments.  All three flags might be used (although they aren't now)
to determine whether a packet can be forwarded; a given host route can
represent a forwardable address if:

	(rt->rt_flags & (RTF_HOST | RTF_LOCAL | RTF_BROADCAST | RTF_MULTICAST))
	== RTF_HOST

Obviously, one still has to do all the work if a host route is not present,
but this code allows one to cache the results of such a lookup if rtalloc1()
is called without masking RTF_PRCLONING.

This is a bulk mport of Mike's IPX/SPX protocol stacks and all the
related gunf that goes with it..
it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..

Mikes been using it for a year or so
but on 2.0

more changes and stuff will be merged in from other developers now that this is in.

3ba6426d14 Change signature of rt->rt_output() so that it is compatible with
ifp->if_output() functions.  This way, initial implementations of
rt_output functionality can just lazily use if_output until customized
versions are written.

18e1f1f110 route.c: keep track of where cloned routes come from, and make sure to
delete them when the ``parent'' goes away

route.h: add glue to track this to rtentry structure.  WARNING WILL ROBINSON!
This will be yet another incompatible change in your route-using binaries.
I apologize, but this was the only way to do it.  I took this opportunity
to increase the size of the metrics to what I believe will be the final
length for 2.1, so that when the T/TCP stuff is done, this won't happen
again.

995add1a12 Add support for two separate cloning flags, one set by the lower layers,
and one set by the protocol family.  Also add another parameter to
rtalloc1() to allow for any interface flags to be ignored; currently
this is only useful for RTF_PRCLONING.  Get rid of rt_prflags and re-unite
with rt_flags.  Add T/TCP ``route metrics''.

NB: YOU MUST RECOMPILE `route' AND OTHER RELATED PROGRAMS AS A RESULT OF
THIS CHANGE.

This also adds a new interface parameter, `ifi_physical', which will
eventually replace IFF_ALTPHYS as the mechanism for specifying the
particular physical connection desired on a multiple-connection card.

NB: YOU MUST RECOMPILE `ifconfig' AND OTHER RELATED PROGRAMS AS A RESULT OF
THIS CHANGE.

f084e01477 Collapse two fields so that we have space for another 32 flags.
NB: You will have to recompile programs which use the `rt_use' member in
order to get the correct values.  This should not cause incorrect operation,
but the statistics may look a little confusing.
