Static wep keys not set

[Nicolas Dichtel]

I've already sent a mail (and a proposal patch) about this issue
(http://lists.shmoo.com/pipermail/hostap/2006-November/014640.html).

As I said in my previous mail:

802.11 specifications say:
"APs set the Privacy subfield to 1 within transmitted Beacon, Probe 
Response, Association Response, and
Reassociation Response management frames if WEP encryption is required 
for all data type frames
exchanged within the BSS. If WEP encryption is not required, the Privacy 
subfield is set to 0."

Regards,
Nicolas
