multicast group memberships. This is not actually operative
at the moment (a lot of other code still needs to be changed), but
this seemed like a useful reference point to check in so that
others (i.e. Bill Fenner) have fair warning of where we are going.
- C++ should be supported for application functions (use __BEGIN_DECLS,
etc.).
- prototypes should be sorted.
- comments on #endif's should spell identifiers the same as the code.
- comments on #endif's should have the same sense as the code (use `!'
to match ifndef, etc.).

(Note that this file has no copyright header; one should probably
be added.)
Use the interface MTU instead of the constant when deciding what
packets to accept.
Allow using the SIOCSIFMTU ioctl (e.g. "ifconfig tun0 mtu XXX") to
set the MTU.
to TAILQs. Fix places which referenced these for no good reason
that I can see (the references remain, but were fixed to compile
again; they are still questionable).
type to be int so that errors can be returned.
2) Use the new SIOCSIFMTU ether_ioctl support in the few drivers that are
using ether_ioctl().
3) In if_fxp.c: treat if_bpf as a token, not as a pointer. Don't bother
testing for FXP_NTXSEG being reached in fxp_start()...just check for
non-NULL 'm'. Change fxp_ioctl() to use ether_ioctl().
1/ increase the tun MTU from 1500 to 1600 to allow it to be used with
packets formatted according to RFC1490 and RFC1717
2/ allow the tsleep() when reading, to be interruptable by signals
so that one can now do:
od -xc </dev/tun0
to dump packets for debugging without getting hung.

Nice but not neccessary in 2.2

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>.
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?

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.
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.)
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!

allow a tunnel interface to be openned even if it has no remote address yet.
this may be needed if you have used
route add default -interface tun0
where the remote end might not even HAVE a number (e.g. netcom links)
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.
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.
when attepmting to add certain types of routes. This problem
only manifested itself in the presence of unconfigured point-to-point
interfaces.

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).
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.
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.
