Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Update copyright on netipx.

Remove historical support for capturing IPX packets in the output path
using raw IPX sockets. While functional, this support is disabled
using a flag that can't be changed from userspace, and google reveals
no documentation or use of that flag anywhere. This eliminates a
potential lock order reversal and code reentrance issue in which the
output path reentered the input path in IPX.

An alternative to removal would be to use the netisr, as a comment I
added in 2005 suggests. While this change is fairly straight-forward,
the lack of any consumers or the easy possibility of consumers (kernel
modification and recompile required) suggests that this is simply an
unused feature.

Update README to remove this TODO, and a TODO regarding IPX/IP
encapsulation which was also removed a few years ago.

MFC after: 1 week

Add a simple netipx TODO list to the end of README, since there are a
number of problems with netipx that I have not yet resolved, and I
don't want them lost track of.

MFC after: 1 month

Update copyright to 2006, comment on my contribution to this code in the
style of previous contributors.

MFC after: 1 month

Update copyright: parts of the netipx implementation are covered by a
2005 copyright.

MFC after: 3 days

Marginally reformat my copyright statement to remove the spurious ','.

/* -> /*- for license, minor formatting changes

Document copyright updates in netipx README as other prior updates have
been documented.

Add $FreeBSD$

This is a bulk mport of Mike's IPX/SPX protocol stacks and all the
related gunf that goes with it..
it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..

Mikes been using it for a year or so
but on 2.0

more changes and stuff will be merged in from other developers now that this is in.
