Expected behaviour is for 84 * an intersection to occur but each device will still use their 85 * respective regulatory requested domains. Subsequent radios will 86 * use the resulting intersection. 87 * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish 88 * this by using a custom beacon-capable regulatory domain for the first 89 * radio. All other device world roam. 90 * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory 91 * domain requests. All radios will adhere to this custom world regulatory 92 * domain. 93 * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory 94 * domain requests. The first radio will adhere to the first custom world 95 * regulatory domain, the second one to the second custom world regulatory 96 * domain. All other devices will world roam. 97 * @HWSIM_REGTEST_STRICT_FOLLOW: Used for testing strict regulatory domain 98 * settings, only the first radio will send a regulatory domain request 99 * and use strict settings. The rest of the radios are expected to follow. 100 * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain 101 * settings. All radios will adhere to this. 102 * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory 103 * domain settings, combined with secondary driver regulatory domain 104 * settings. The first radio will get a strict regulatory domain setting 105 * using the first driver regulatory request and the second radio will use 106 * non-strict settings using the second driver regulatory request. All 107 * other devices should follow the intersection created between the 108 * first two. 109 * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need 110 * at least 6 radios for a complete test. We will test in this order: 111 * 1 - driver custom world regulatory domain 112 * 2 - second custom world regulatory domain 113 * 3 - first driver regulatory domain request 114 * 4 - second driver regulatory domain request 115 * 5 - strict regulatory domain settings using the third driver regulatory 116 * domain request 117 * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio 118 * regulatory requests. 119 * 120 * These are the different values you can use for the regtest 121 * module parameter. This is useful to help test world roaming 122 * and the driver regulatory_hint() call and combinations of these. 123 * If you want to do specific alpha2 regulatory domain tests simply 124 * use the userspace regulatory request as that will be respected as 125 * well without the need of this module parameter. This is designed 126 * only for testing the driver regulatory request, world roaming 127 * and all possible combinations. 128 */ 129 enum hwsim_regtest { 130 HWSIM_REGTEST_DISABLED = 0, 131 HWSIM_REGTEST_DRIVER_REG_FOLLOW = 1, 132 HWSIM_REGTEST_DRIVER_REG_ALL = 2, 133 HWSIM_REGTEST_DIFF_COUNTRY = 3, 134 HWSIM_REGTEST_WORLD_ROAM = 4, 135 HWSIM_REGTEST_CUSTOM_WORLD = 5, 136 HWSIM_REGTEST_CUSTOM_WORLD_2 = 6, 137 HWSIM_REGTEST_STRICT_FOLLOW = 7, 138 HWSIM_REGTEST_STRICT_ALL = 8, 139 HWSIM_REGTEST_STRICT_AND_DRIVER_REG = 9, 140 HWSIM_REGTEST_ALL = 10, 141 };
