4458ac71b1 Removed nested include if <sys/socket.h> from <net/if.h> and
<net/if_arp.h> and fixed the things that depended on it.  The nested
include just allowed unportable programs to compile and made my
simple #include checking program report that networking code doesn't
need to include <sys/socket.h>.

b0a76b8898 No code changes what so ever, but added about 150 lines of comments
Sorry if this makes it harder to merge in lite2 stuff but hey..
At least I can figure out what is going on whenever I end up going through those
files again..

do we have a policy regarding commenting existing code?

704b066633 Bugfix and simplification for rev 1.34: make sure that the route
is non-null before trying to delete it in rt_setgate(), which then
allows removal of the special-case code from the RTM_ADD case.
This should fix the panics that joerg and Phil Karn have been seeing.

1de1c45200 Add some padding to struct ifmibdata and move the `struct ifdata' to
the end of that sstructure to make evolution easier.

Add definitions for the 802.3/Ethernet MIB.  To implement this, simply
add a `struct ifmib_iso_8802_3' somewhere in your interface's softc,
point if_linkmib to it, set if_linkmiblen, and fill in the statistics
with appropriate values.  (I didn't want to create Yet Another Ethernet-
related header file, otherwise this would have been separated out.)

3271a3a4f3 route.c:RTM_ADD does not check for a netmask before doing a tree walk
like it does elsewhere.  This is probably only happens when incorrect
args are given to route(8), or when running with non-IPv4 stacks but
incorrect args to the route command is no excuse for panicing!

this may be needed if you have used
route add default -interface tun0

This is a patch to sys/net/if.c. What it does is patch the algorithm
for finding an IP address on an interface which most closely matches
a given IP address. The problem with it is when no address matches,
and you have to just pick one at random. Then the code ends up picking
the last IP address in the list. This patch changes things so it
picks up the first address instead.
Usually the first address is more useful as the later ones are aliases.

bbd17bf8e1 Add better support for retrieving management information from network
interfaces.  This creates two new tables in the net.link.generic branch
of the MIB; one contains (essentially) `ifdata' structures, and the other
contains a blob provided by the interface (and presumably used to
implement link-layer-specific MIB variables).  A number of things
have been moved around in the `ifnet' and `ifdata' structures, so
NEW VERSIONS OF ifconfig(8) AND routed(8) ARE REQUIRED.  (A simple
recompile is all that's necessary.)

I have a sample program which uses this interface for those interested
in making use of it.

6f86639187 Add a new, better mechanism for sticking packets onto ifqueues.
The old system had the misfeature that the only policy it could implement
was tail-drop; the new IF_ENQ_DROP macro/function makes it possible
to implement more sophisticated queueing policies on a system-wide
basis.  No code actually uses this yet (although on my machine
I have converted the ethernet and (polled) loopback to use it).

2c37256e5a Modify the kernel to use the new pr_usrreqs interface rather than the old
pr_usrreq mechanism which was poorly designed and error-prone.  This
commit renames pr_usrreq to pr_ousrreq so that old code which depended on it
would break in an obvious manner.  This commit also implements the new
interface for TCP, although the old function is left as an example
(#ifdef'ed out).  This commit ALSO fixes a longstanding bug in the
TCP timer processing (introduced by davidg on 1995/04/12) which caused
timer processing on a TCB to always stop after a single timer had
expired (because it misinterpreted the return value from tcp_usrreq()
to indicate that the TCB had been deleted).  Finally, some code
related to polling has been deleted from if.c because it is not
relevant t -current and doesn't look at all like my current code.

1db1fffa03 Disallow host routes that point to themselves. These routes serve no
purpose, other than to get in the way of the ARP table and cause
"can't allocate llinfo" errors.

This change may cause gated or routed to start complaining when adding
such routes.  If so, these programs will need to be fixed to not try
to add these routes.
