Hi,

I am pretty sure that the mac80211 code doesn't handle WEP with shared keys 
correctly. Using the ath9k driver on my MacBook I am unable to put the driver 
into restricted mode (shared key). It stays in open mode. That is the following 
command has no effect: iwconfig wlan0 enc restricted. I can also confirm this 
when looking at the authentication packets that go over the air: they are sent 
with the open flag, and not the shared key flag.

Surprisingly nowhere in the mac80211 code the ifsta->auth_alg is set to 
WLAN_AUTH_SHARED_KEY so far. The attached small patch does just that. I am not 
100% sure if that's the way to do it, so please review carefully.

With this patch authentication works. The AP now denies association, but that is 
another problem.

Cheers

Ortwin
