/**
 * parse_freqchan - Parse frequency or channel definition
 *
 * @chandef: chandef structure to be filled in
 * @chan: Boolean whether to parse a channel or frequency based specifier
 * @argc: Number of arguments
 * @argv: Array of string arguments
 * @parsed: Pointer to return the number of used arguments, or NULL to error
 *          out if any argument is left unused.
 * @freq_in_khz: Boolean whether to parse the frequency in kHz or default as MHz
 *
 * The given chandef structure will be filled in from the command line
 * arguments. argc/argv will be updated so that further arguments from the
 * command line can be parsed.
 *
 * Note that despite the fact that the function knows how many center freqs
 * are needed, there's an ambiguity if the next argument after this is an
 * integer argument, since the valid channel width values are interpreted
 * as such, rather than a following argument. This can be avoided by the
 * user by giving "NOHT" instead.
 *
 * The working specifier if chan is set are:
 *   <channel> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz|160MHz|320MHz]
 *
 * And if frequency is set:
 *   <freq> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz|160MHz|320MHz]
 *   <control freq> [5|10|20|40|80|80+80|160|320] [<center1_freq> [<center2_freq>]]
 *
 * If the mode/channel width is not given the NOHT is assumed.
 *
 * Return: Number of used arguments, zero or negative error number otherwise
