/**
|
||||
* 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.
