/**
* 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.
