Expected behaviour is for 88 * an intersection to occur but each device will still use their 89 * respective regulatory requested domains. Subsequent radios will 90 * use the resulting intersection. 91 * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish 92 * this by using a custom beacon-capable regulatory domain for the first 93 * radio. All other device world roam. 94 * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory 95 * domain requests. All radios will adhere to this custom world regulatory 96 * domain. 97 * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory 98 * domain requests. The first radio will adhere to the first custom world 99 * regulatory domain, the second one to the second custom world regulatory 100 * domain. All other devices will world roam. 101 * @HWSIM_REGTEST_STRICT_FOLLOW: Used for testing strict regulatory domain 102 * settings, only the first radio will send a regulatory domain request 103 * and use strict settings. The rest of the radios are expected to follow. 104 * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain 105 * settings. All radios will adhere to this. 106 * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory 107 * domain settings, combined with secondary driver regulatory domain 108 * settings. The first radio will get a strict regulatory domain setting 109 * using the first driver regulatory request and the second radio will use 110 * non-strict settings using the second driver regulatory request. All 111 * other devices should follow the intersection created between the 112 * first two. 113 * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need 114 * at least 6 radios for a complete test. We will test in this order: 115 * 1 - driver custom world regulatory domain 116 * 2 - second custom world regulatory domain 117 * 3 - first driver regulatory domain request 118 * 4 - second driver regulatory domain request 119 * 5 - strict regulatory domain settings using the third driver regulatory 120 * domain request 121 * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio 122 * regulatory requests. 123 * 124 * These are the different values you can use for the regtest 125 * module parameter. This is useful to help test world roaming 126 * and the driver regulatory_hint() call and combinations of these. 127 * If you want to do specific alpha2 regulatory domain tests simply 128 * use the userspace regulatory request as that will be respected as 129 * well without the need of this module parameter.
