| * enum hwsim_regtest - the type of regulatory tests we offer |
| * |
| * These are the different values you can use for the regtest |
| * module parameter. This is useful to help test world roaming |
| * and the driver regulatory_hint() call and combinations of these. |
| * If you want to do specific alpha2 regulatory domain tests simply |
| * use the userspace regulatory request as that will be respected as |
| * well without the need of this module parameter. This is designed |
| * only for testing the driver regulatory request, world roaming |
| * and all possible combinations. |
| * |
| * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed, |
| * this is the default value. |
| * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory |
| * hint, only one driver regulatory hint will be sent as such the |
| * secondary radios are expected to follow. |
| * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory |
| * request with all radios reporting the same regulatory domain. |
| * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling |
| * different regulatory domains requests. Expected behaviour is for |
| * an intersection to occur but each device will still use their |
| * respective regulatory requested domains. Subsequent radios will |
| * use the resulting intersection. |
| * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We acomplish |
| * this by using a custom beacon-capable regulatory domain for the first |
| * radio. All other device world roam. |
| * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory |
| * domain requests. All radios will adhere to this custom world regulatory |
| * domain. |
| * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory |
| * domain requests. The first radio will adhere to the first custom world |
| * regulatory domain, the second one to the second custom world regulatory |
| * domain. All other devices will world roam. |
| * @HWSIM_REGTEST_STRICT_FOLLOW_: Used for testing strict regulatory domain |
| * settings, only the first radio will send a regulatory domain request |
| * and use strict settings. The rest of the radios are expected to follow. |
| * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain |
| * settings. All radios will adhere to this. |
| * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory |
| * domain settings, combined with secondary driver regulatory domain |
| * settings. The first radio will get a strict regulatory domain setting |
| * using the first driver regulatory request and the second radio will use |
| * non-strict settings using the second driver regulatory request. All |
| * other devices should follow the intersection created between the |
| * first two. |
| * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need |
| * at least 6 radios for a complete test. We will test in this order: |
| * 1 - driver custom world regulatory domain |
| * 2 - second custom world regulatory domain |
| * 3 - first driver regulatory domain request |
| * 4 - second driver regulatory domain request |
| * 5 - strict regulatory domain settings using the third driver regulatory |
| * domain request |
| * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio |
| * regulatory requests. |
