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.
