Expected behaviour is for 91 * an intersection to occur but each device will still use their 92 * respective regulatory requested domains. Subsequent radios will 93 * use the resulting intersection. 94 * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish 95 * this by using a custom beacon-capable regulatory domain for the first 96 * radio. All other device world roam. 97 * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory 98 * domain requests. All radios will adhere to this custom world regulatory 99 * domain. 100 * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory 101 * domain requests. The first radio will adhere to the first custom world 102 * regulatory domain, the second one to the second custom world regulatory 103 * domain. All other devices will world roam. 104 * @HWSIM_REGTEST_STRICT_FOLLOW: Used for testing strict regulatory domain 105 * settings, only the first radio will send a regulatory domain request 106 * and use strict settings. The rest of the radios are expected to follow. 107 * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain 108 * settings. All radios will adhere to this. 109 * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory 110 * domain settings, combined with secondary driver regulatory domain 111 * settings. The first radio will get a strict regulatory domain setting 112 * using the first driver regulatory request and the second radio will use 113 * non-strict settings using the second driver regulatory request. All 114 * other devices should follow the intersection created between the 115 * first two. 116 * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need 117 * at least 6 radios for a complete test. We will test in this order: 118 * 1 - driver custom world regulatory domain 119 * 2 - second custom world regulatory domain 120 * 3 - first driver regulatory domain request 121 * 4 - second driver regulatory domain request 122 * 5 - strict regulatory domain settings using the third driver regulatory 123 * domain request 124 * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio 125 * regulatory requests. 126 * 127 * These are the different values you can use for the regtest 128 * module parameter. This is useful to help test world roaming 129 * and the driver regulatory_hint() call and combinations of these. 130 * If you want to do specific alpha2 regulatory domain tests simply 131 * use the userspace regulatory request as that will be respected as 132 * well without the need of this module parameter. This is designed 133 * only for testing the driver regulatory request, world roaming 134 * and all possible combinations. 135 */ 136 enum hwsim_regtest { 137 HWSIM_REGTEST_DISABLED = 0, 138 HWSIM_REGTEST_DRIVER_REG_FOLLOW = 1, 139 HWSIM_REGTEST_DRIVER_REG_ALL = 2, 140 HWSIM_REGTEST_DIFF_COUNTRY = 3, 141 HWSIM_REGTEST_WORLD_ROAM = 4, 142 HWSIM_REGTEST_CUSTOM_WORLD = 5, 143 HWSIM_REGTEST_CUSTOM_WORLD_2 = 6, 144 HWSIM_REGTEST_STRICT_FOLLOW = 7, 145 HWSIM_REGTEST_STRICT_ALL = 8, 146 HWSIM_REGTEST_STRICT_AND_DRIVER_REG = 9, 147 HWSIM_REGTEST_ALL = 10, 148 };
