| 36 | * enum hwsim_regtest - the type of regulatory tests we offer |
| 37 | * |
| 38 | * These are the different values you can use for the regtest |
| 39 | * module parameter. This is useful to help test world roaming |
| 40 | * and the driver regulatory_hint() call and combinations of these. |
| 41 | * If you want to do specific alpha2 regulatory domain tests simply |
| 42 | * use the userspace regulatory request as that will be respected as |
| 43 | * well without the need of this module parameter. This is designed |
| 44 | * only for testing the driver regulatory request, world roaming |
| 45 | * and all possible combinations. |
| 46 | * |
| 47 | * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed, |
| 48 | * this is the default value. |
| 49 | * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory |
| 50 | * hint, only one driver regulatory hint will be sent as such the |
| 51 | * secondary radios are expected to follow. |
| 52 | * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory |
| 53 | * request with all radios reporting the same regulatory domain. |
| 54 | * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling |
| 55 | * different regulatory domains requests. Expected behaviour is for |
| 56 | * an intersection to occur but each device will still use their |
| 57 | * respective regulatory requested domains. Subsequent radios will |
| 58 | * use the resulting intersection. |
| 59 | * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We acomplish |
| 60 | * this by using a custom beacon-capable regulatory domain for the first |
| 61 | * radio. All other device world roam. |
| 62 | * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory |
| 63 | * domain requests. All radios will adhere to this custom world regulatory |
| 64 | * domain. |
| 65 | * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory |
| 66 | * domain requests. The first radio will adhere to the first custom world |
| 67 | * regulatory domain, the second one to the second custom world regulatory |
| 68 | * domain. All other devices will world roam. |
| 69 | * @HWSIM_REGTEST_STRICT_FOLLOW_: Used for testing strict regulatory domain |
| 70 | * settings, only the first radio will send a regulatory domain request |
| 71 | * and use strict settings. The rest of the radios are expected to follow. |
| 72 | * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain |
| 73 | * settings. All radios will adhere to this. |
| 74 | * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory |
| 75 | * domain settings, combined with secondary driver regulatory domain |
| 76 | * settings. The first radio will get a strict regulatory domain setting |
| 77 | * using the first driver regulatory request and the second radio will use |
| 78 | * non-strict settings using the second driver regulatory request. All |
| 79 | * other devices should follow the intersection created between the |
| 80 | * first two. |
| 81 | * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need |
| 82 | * at least 6 radios for a complete test. We will test in this order: |
| 83 | * 1 - driver custom world regulatory domain |
| 84 | * 2 - second custom world regulatory domain |
| 85 | * 3 - first driver regulatory domain request |
| 86 | * 4 - second driver regulatory domain request |
| 87 | * 5 - strict regulatory domain settings using the third driver regulatory |
| 88 | * domain request |
| 89 | * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio |
| 90 | * regulatory requests. |
