IP aliases aren't really any different than the primary IP address on an

IPv6 scoped addr display is not yet supported by ifconfig
and route. Now almost of IPv6 apps support it, so its support
in ifconfig and route is important to keep consisetncy, and
to avoid user confusion.

we're about to operate on, try to load one. Don't complain if the
load fails, and always press on regardless (there may not be a module
suitable or required).
With the renaming of the PCI ethernet driver modules and the addition
of appropriate miibus dependancies on those modules that need it, it is
now no longer necessary to compile many ethernet drivers into the kernel;
they will be loaded on demand the first time they are ifconfig'ed.

This is inteded for to allow ifconfig to print various unstructured

The data is returned from the kernel in ASCII form, see the comment in
if.h for some technicalities.

Now tun* interfaces tell the PID of the process which opened them.

This means that the driver will add/delete routes when it knows it is
up/down, rather than have the generic code belive it is up if configured.
This is probably most useful for serial lines, although many PHY chips
could probably tell us if we're connected to the cable/hub as well.

- parse command options using getopt for consistancy
- sanitise the command parsing so that it's less like spaghetti
- implement a "-l" option (idea from NetBSD - just list names)
- attempt to clean up the sysctl parsing loop some more. It still needs
to be taken out the back and shot though.
- cut down on global usage, but there's a lot more scope for this.
- make usage string a bit closer to reality (it was missing lots of things)
Unfortunately, I did this for the second time but with the memory of
the NetBSD version still recently in my mind. It's hard to redo simple
changes or getopt stuff without making it look like what you've been
working with a few hours ago.
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.

other #include messes while we're at it.
- Don't link against libkvm and don't uselessly include <kvm.h>.
- Declare constant objects as const.
- Declare functions with the correct types.
- Call functions with the correct parameters.
Not fixed:
- The sysctl parsing remains ugly (but it may be the best we can do).
- atnetrange() should use strtoul() rather than sscanf() for better
error checking.

The main reason for this commit was that an "ifconfig -a" would also show
the AF_INET addresses in AF_IPX form (if the kernel was configured for IPX)

I apologise to the world for propagating the ugliness of some of the code

in the man page. ifconfig -au affects all interfaces marked as up,
and ifconfig -ad affects only the interfaces marked down. ifconfig -a
still handles everything. This change is purely for compatibility with
SunOS, for those who might be accustomed to the SunOS ifconfig's
behavior.
- The -a flag now works just as it does in SunOS: '-a' is actually
handled like a wildcard for all interfaces. 'ifconfig -a' displays
the status of all interfaces, 'ifconfig -a netmask 0xffffff00' sets
the netmask of all interfaces, and so forth. I don't know if many
people really need to be able to set the netmasks of all interfaces
at once, but the SunOS ifconfig seems to allow this, so there you
have it.
- An 'ether_status' function has been added to display the ethernet
address of all ethernet interfaces. Again, as in SunOS, you must
be root in order for this to work. The ethernet address is read
from /dev/kmem using kvm_open() and kvm_read(), much in the same
was as it's done with netstat. If you choose to install ifconfig
set-gid kmem then normal users will be able to see the ethernet
address as well, though this may not be desireable. This feature
requires a small change to the ifconfig Makefile: you need to link
with -lkvm in order to use the kvm_*() functions.
