Hello,

there is some think that i don't understand in 
wpa_supplicant/wpa_supplicant.c file
     void wpa_supplicant_associate(struct wpa_supplicant *wpa_s,
                               struct wpa_bss *bss, struct wpa_ssid 
*ssid) function

Why we fixed ssid in struct wpa_driver_associate_params  with struct 
wpa_bss *bss or struct wpa_ssid *ssid.
Why we coun't allway fixed ssid with wpa_ssid *ssid as in my patch?

best regards,
Sylvain

wpa_supplicant supports network configuration blocks that use wildcard
SSID, i.e., ssid->ssid may be NULL in which case the SSID has to be
copied from the BSS entry (scan result).
