Public bug reported:

If some driver implements wext interface and nl80211 interface the
latter is preferred. With the ipw2200 driver this implementation doesn't
yield any encryption capabilites but the wext interface is never
consulted. If the order of the function calls is reversed in wifi-
utils.c the problem is solved for me and I dont have a regression with
ath5k.
