+ * 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 acomplish
+ * 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
