cfg80211: fix channel setting for wext
Patch fixes the bug at http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2139 Currently we cannot set the channel using wext extension if we have already associated and disconnected. As cfg80211_mgd_wext_siwfreq will not switch the channel if ssid is set. This fixes it by clearing the ssid. Following is the sequence which it tries to fix. modprobe iwlagn iwconfig wlan0 essid "" ifconfig wlan0 down iwconfig wlan0 chan X wext is marked as deprecate.If we use nl80211 we can easily play with setting the channel.
