This is from the nl80211 driver interface..

while this is from the WEXT driver interface.

In other words, this is comparing apples and oranges.. It does not look
like the driver you are using would support nl80211 properly. As such,
you may need to use driver_wext.c (-Dwext on wpa_supplicant command
line) with the newer version as well.
