Hi!

This is not a show stopper for me, but some of you may want to deprecate 
the wireless extension kernel option.

I have a configuration where scanning and association attempt work fine 
from wpa_supplicant when the wpa_priv utility is started with wext:wlan1 
but not with nl80211:wlan1.

If I try the not-performing variant (nl80211), I need to remove and 
install the wifi module (rtl8192ce) for the other one to perform OK. 
 From a fresh boot, this performing wext variant works fine the first time.

I have traces from wpa_priv, wpa_supplicant, and wpa_cli from either 
options. Same configuration files for build time and run time.

Tried with various kernel options. A portion of the most recent kernel 
config is attached.

If I can be of assistance for improving the Linux Wi-Fi support, let me 
know.
