Subject: RFC airo : wpa support

Hi,

I attach a diff against 2.6.21 for adding wpa support for airo driver.
In then end of 2005 I manage to make work wpa but the code was really 
ugly. I manage to find some time to clean it.

To support wpa, a new interface of the firmware should be used. This 
interface is incompatible with the old interface and using both 
interface at the same time make the firmware hang.

Porting OPEN and WEP mode to new interface need some driver rewrite, and 
the old interface should be keep for the older cards (or the cards that 
doesn't have newer firmware).
That's why I didn't do it, and I added a module parameter for choosing 
between the old driver behavior (with no wpa support) or the driver with 
wpa only support.

The wireless extension handlers are a bit ugly, I will be very happy, if 
somebody could help me to clean them.

Any comments are appreciated.

Matthieu

PS : the lastest version of the driver can be found in 
http://svn.gna.org/viewcvs/airo-wpa/branches/kernel/

PS2 : There is some remaining trace in the driver for debug purpose, 
that will be removed in the final version
