/**
 * 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 accomplish
 *      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.
