+ * @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.
+ *
+ * The given chandef structure will be filled in from the command line

+ * Note that no integer argument may follow a frequency definition to allow the
+ * user to skip the center frequency definition(s).
+ *
+ * The working specifier if chan is set are:
+ * <channel> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz]
+ *
+ * And if frequency is set:
+ * <freq> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz]
+ * <control freq> [5|10|20|40|80|80+80|160] [<center1_freq> [<center2_freq>]]
+ *
+ * If the mode/channel width is not given the NOHT is assumed.
