This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.
TODO:
- The definitions of SADB_* in sys/net/pfkeyv2.h are still different
from RFC2407/IANA assignment because of binary compatibility
issue. It should be fixed under 5-CURRENT.
- ip6po_m member of struct ip6_pktopts is no longer used. But, it
is still there because of binary compatibility issue. It should
be removed under 5-CURRENT.

despite the fact that most people want to set exactly the same settings
regardless of which card they have. It has been repeatidly suggested
that this configuration should be done via ifconfig. This patch
implements the required functionality in ifconfig and add support to the
wi and an drivers. It also provides partial, untested support for the
awi driver.

address on an interface. This basically allows you to do what my
little setmac module/utility does via ifconfig. This involves the
following changes:
socket.h: define SIOCSIFLLADDR
if.c: add support for SIOCSIFLLADDR, which resets the values in
the arpcom struct and sockaddr_dl for the specified interface.
Note that if the interface is already up, we need to down/up
it in order to program the underlying hardware's receive filter.
ifconfig.c: add lladdr command
ifconfig.8: document lladdr command
You can now force the MAC address on any ethernet interface to be
whatever you want. (The change is not sticky across reboots of course:
we don't actually reprogram the EEPROM or anything.) Actually, you
can reprogram the MAC address on other kinds of interfaces too; this
shouldn't be ethernet-specific (though at the moment it's limited to
6 bytes of address data).
Nobody ran up to me and said "this is the politically correct way to
do this!" so I don't want to hear any complaints from people who think
I could have done it more elegantly. Consider yourselves lucky I didn't
do it by having ifconfig tread all over /dev/kmem.
Improve compatibility with BSD/OS, and also more accurately reflect that
IP aliases aren't really any different than the primary IP address on an
interface.

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.

- 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
