61 | * enum hwsim_regtest - the type of regulatory tests we offer | |
62 | * | |
63 | * These are the different values you can use for the regtest | |
64 | * module parameter. This is useful to help test world roaming | |
65 | * and the driver regulatory_hint() call and combinations of these. | |
66 | * If you want to do specific alpha2 regulatory domain tests simply | |
67 | * use the userspace regulatory request as that will be respected as | |
68 | * well without the need of this module parameter. This is designed | |
69 | * only for testing the driver regulatory request, world roaming | |
70 | * and all possible combinations. | |
71 | * | |
72 | * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed, | |
73 | * this is the default value. | |
74 | * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory | |
75 | * hint, only one driver regulatory hint will be sent as such the | |
76 | * secondary radios are expected to follow. | |
77 | * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory | |
78 | * request with all radios reporting the same regulatory domain. | |
79 | * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling | |
80 | * different regulatory domains requests. Expected behaviour is for | |
81 | * an intersection to occur but each device will still use their | |
82 | * respective regulatory requested domains. Subsequent radios will | |
83 | * use the resulting intersection. | |
25985edc | 84 | * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish |
4a5af9c2 LR |
85 | * this by using a custom beacon-capable regulatory domain for the first |
86 | * radio. All other device world roam. | |
87 | * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory | |
88 | * domain requests. All radios will adhere to this custom world regulatory | |
89 | * domain. | |
90 | * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory | |
91 | * domain requests. The first radio will adhere to the first custom world | |
92 | * regulatory domain, the second one to the second custom world regulatory | |
93 | * domain. All other devices will world roam. | |
94 | * @HWSIM_REGTEST_STRICT_FOLLOW_: Used for testing strict regulatory domain | |
95 | * settings, only the first radio will send a regulatory domain request | |
96 | * and use strict settings. The rest of the radios are expected to follow. | |
97 | * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain | |
98 | * settings. All radios will adhere to this. | |
99 | * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory | |
100 | * domain settings, combined with secondary driver regulatory domain | |
101 | * settings. The first radio will get a strict regulatory domain setting | |
102 | * using the first driver regulatory request and the second radio will use | |
103 | * non-strict settings using the second driver regulatory request. All | |
104 | * other devices should follow the intersection created between the | |
105 | * first two. | |
106 | * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need | |
107 | * at least 6 radios for a complete test. We will test in this order: | |
108 | * 1 - driver custom world regulatory domain | |
109 | * 2 - second custom world regulatory domain | |
110 | * 3 - first driver regulatory domain request | |
111 | * 4 - second driver regulatory domain request | |
112 | * 5 - strict regulatory domain settings using the third driver regulatory | |
113 | * domain request | |
114 | * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio | |
115 | * regulatory requests. | |
