906f09bca4 Add a macro to accurately calculate the length of a struct ifreq when
it contains an address.  This can replace all the myriad (wrong) ways
in which this task is performed in the current system.  As an added
bonus, since it's a macro, then third-party software vendors have an easy
way to tell whether it's there or not.  (This will become necessary
when sizeof(struct sockaddr) is increaased, and also when additional
fields are added to struct ifreq.)

a1c995b626 Last major round (Unless Bruce thinks of somthing :-) of malloc changes.
Distribute all but the most fundamental malloc types.  This time I also
remembered the trick to making things static:  Put "static" in front of
them.

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).

fb5831565c 1) Implement SIOCSIFMTU in ether_ioctl(), and change ether_ioctl's return
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().

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>.

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).

9b44ff2214 Clean up Ethernet drivers:
- fill in and use ifp->if_softc
	- use if_bpf rather than private cookie variables
	- change bpf interface to take advantage of this
	- call ether_ifattach() directly from Ethernet drivers
	- delete kludge in if_attach() that did this indirectly

7c399a896a Delete the if_private[] array in struct ifnet; this turned out to be
of limited utility.  In their place, add bunch of pointers
which will eventually be needed by the polled-interrupt scheme we're working
here.  (It will probably be a while before the code is written and
committed here.)  At the same time, a `void *if_softc' field
was added to the beginning of the structure to make certain driver
writers happier.

The practical upshot of all this is that you need to
recompile utilities such as netstat which manipulate struct ifnet.

4a5f1499b0 all:
Removed ifnet.if_init and ifnet.if_reset as they are generally unused.
Change the parameter passed to if_watchdog to be a ifnet * rather than
a unit number. All of this is an attempt to move toward not needing an
array of softc pointers (which is usually static in size) to point to
the driver softc.

if_ed.c:
Changed some of the argument passing to some functions to make a little
more sense.

if_ep.c, if_vx.c:
Killed completely bogus use of if_timer. It was being set in such a way
that the interface was being reset once per second (blech!).

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.

f23b4c91c4 Fix up some sloppy coding practices:
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
  header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.
