| 716 | * @argc: Number of arguments |
| 717 | * @argv: Array of string arguments |
| 718 | * @parsed: Pointer to return the number of used arguments, or NULL to error |
| 719 | * out if any argument is left unused. |
| 720 | * |
| 721 | * The given chandef structure will be filled in from the command line |
| 722 | * arguments. argc/argv will be updated so that further arguments from the |
| 723 | * command line can be parsed. |
| 724 | * |
| 725 | * Note that despite the fact that the function knows how many center freqs |
| 726 | * are needed, there's an ambiguity if the next argument after this is an |
| 727 | * integer argument, since the valid channel width values are interpreted |
| 728 | * as such, rather than a following argument. This can be avoided by the |
| 729 | * user by giving "NOHT" instead. |
| 730 | * |
| 731 | * The working specifier if chan is set are: |
| 732 | * <channel> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz|160MHz] |
| 733 | * |
| 734 | * And if frequency is set: |
| 735 | * <freq> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz|160MHz] |
| 736 | * <control freq> [5|10|20|40|80|80+80|160] [<center1_freq> [<center2_freq>]] |
| 737 | * |
| 738 | * If the mode/channel width is not given the NOHT is assumed. |
