73 | * enum hwsim_regtest - the type of regulatory tests we offer |
74 | * |
75 | * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed, |
76 | * this is the default value. |
77 | * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory |
78 | * hint, only one driver regulatory hint will be sent as such the |
79 | * secondary radios are expected to follow. |
80 | * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory |
81 | * request with all radios reporting the same regulatory domain. |
82 | * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling |
83 | * different regulatory domains requests. 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. |
