688 * Note that despite the fact that the function knows how many center freqs
689 * are needed, there's an ambiguity if the next argument after this is an
690 * integer argument, since the valid channel width values are interpreted
691 * as such, rather than a following argument. This can be avoided by the
692 * user by giving "NOHT" instead.
693 *
694 * The working specifier if chan is set are:
695 * <channel> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz]
696 *
697 * And if frequency is set:

699 * <control freq> [5|10|20|40|80|80+80|160] [<center1_freq> [<center2_freq>]]
