ipw driver

[Johannes Hofmann]

Hello, 

just wanted to know, if anyone is porting the ipw driver
(http://damien.bergamini.free.fr/ipw/) to DragonFly. I just did a "brute
force" attempt and it actually works! It seems to be pretty easy to port, 
as Joerg has already brought in all the ieee80211 stuff.
I just removed all locking and adjusted some function arguments. This is
probably not quite the right way to do it :-). Is there any locking needed on
DragonFly? I did not find anything in the wi(4) driver.

Thanks,
Johannes
