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.

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.
