Intel Wireless Driver update snapshot for some testing

Hi everyone,

I am happy to finally give you something to test as a start
for FreeBSD HEAD.

Please don't consider it fit for daily use yet.
It is far from being perfect yet but if you are blessed it may be
usable for a bit.  I had a ping6 running for around 23 hours, been
browsing the web or downloaded (though slowly) a FreeBSD release
image.  At other times while I was out it was entirely acting up.

I just want to get the code out as-is and then give you an
update every few days/week rather than letting you wait if
there will be anything.

It'll also give us a better understanding on what issues need
most attention first.

There's a wiki page detailing some of the things and I'll keep
updating that and adding to it as things go on.

Lots of health,
Bjoern
