From: Greg KH <[email protected]> 3.5-stable review patch. If anyone has any objections, please let me know.
------------------ From: Ilan Peer <[email protected]> commit e19ebcab01cc130fa832764d453b263460ec3b91 upstream. It is possible that the BSS context is not active (for example when the current mode is set to GO), or that the vif->type is different than station. In such a case we cannot call mac80211 to report the average rssi for the interface (the function assumes that the vif is valid and that the type is station).
