Since the bss is always set now once we are connected, if the bss has its own information element we refer to it and pass that instead of relying on mac80211's parsing. Now all cfg80211 drivers get country IE support, automatically and we reduce the call overhead that we had on mac80211 which called this upon every beacon and instead now call this only upon a successfull connection by a STA on cfg80211.
