Error message says that IOCTL used by wpa_supplicant to communicate with
the driver isn't supported by the driver. Please recompile the driver
with the CONFIG_IEEE80211_WPA defined. 

Also, as the data structure passed from wpa_supplicant to ipw* driver
has changed in the latest unstable wpa_supplicant you have to use patch
mentioned in this thread.
