/**
* 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.
