In wext there is encoding setting for static keys only for wep and
extended encoding for dynamic keys including wep keys. In mac80211
both setting are funneled to the same point which is incorrect since
the usage is not the same. The major problem is in HW acceleration.
The static wep keys are passed as belonging to the station with
broadcast address and the driver cannot distinguish if the wep key is
dynamic key for the bcast address or it is a static wep key that has
to be used for all traffic. The problem is of course visible mostly in
AP mode.
