  73  * enum hwsim_regtest - the type of regulatory tests we offer
  74  *
  75  * These are the different values you can use for the regtest
  76  * module parameter. This is useful to help test world roaming
  77  * and the driver regulatory_hint() call and combinations of these.
  78  * If you want to do specific alpha2 regulatory domain tests simply
  79  * use the userspace regulatory request as that will be respected as
  80  * well without the need of this module parameter. This is designed
  81  * only for testing the driver regulatory request, world roaming
  82  * and all possible combinations.
  83  *
  84  * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed,
  85  *      this is the default value.
  86  * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory
  87  *      hint, only one driver regulatory hint will be sent as such the
  88  *      secondary radios are expected to follow.
  89  * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory
  90  *      request with all radios reporting the same regulatory domain.
  91  * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling
  92  *      different regulatory domains requests. Expected behaviour is for
  93  *      an intersection to occur but each device will still use their
  94  *      respective regulatory requested domains. Subsequent radios will
  95  *      use the resulting intersection.
  96  * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish
  97  *      this by using a custom beacon-capable regulatory domain for the first
  98  *      radio. All other device world roam.
  99  * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory
 100  *      domain requests. All radios will adhere to this custom world regulatory
 101  *      domain.
 102  * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory
 103  *      domain requests. The first radio will adhere to the first custom world
 104  *      regulatory domain, the second one to the second custom world regulatory
 105  *      domain. All other devices will world roam.
 106  * @HWSIM_REGTEST_STRICT_FOLLOW: Used for testing strict regulatory domain
 107  *      settings, only the first radio will send a regulatory domain request
 108  *      and use strict settings. The rest of the radios are expected to follow.
 109  * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain
 110  *      settings. All radios will adhere to this.
 111  * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory
 112  *      domain settings, combined with secondary driver regulatory domain
 113  *      settings. The first radio will get a strict regulatory domain setting
 114  *      using the first driver regulatory request and the second radio will use
 115  *      non-strict settings using the second driver regulatory request. All
 116  *      other devices should follow the intersection created between the
 117  *      first two.
 118  * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need
 119  *      at least 6 radios for a complete test. We will test in this order:
 120  *      1 - driver custom world regulatory domain
 121  *      2 - second custom world regulatory domain
 122  *      3 - first driver regulatory domain request
 123  *      4 - second driver regulatory domain request
 124  *      5 - strict regulatory domain settings using the third driver regulatory
 125  *          domain request
 126  *      6 and on - should follow the intersection of the 3rd, 4rth and 5th radio
 127  *                 regulatory requests.
