For a\nnon-transmitted MBSSID profile those pointers refer to merged-profile\nstorage owned by the parse object, and the fallback block frees that\nobject at its end. The copied pointers are used afterwards to determine\nthe operating channel, configure bandwidth, and apply HT capabilities.\n\nKeep the fallback parse result alive until association setup finishes.\n\n[reorder variable declaration]"
