73 * enum hwsim_regtest - the type of regulatory tests we offer
75 * These are the different values you can use for the regtest
76 * module parameter. This is useful to help test world roaming
77 * and the driver regulatory_hint() call and combinations of these.
78 * If you want to do specific alpha2 regulatory domain tests simply
79 * use the userspace regulatory request as that will be respected as
80 * well without the need of this module parameter. This is designed
81 * only for testing the driver regulatory request, world roaming
82 * and all possible combinations.
84 * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed,
85 * this is the default value.
86 * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory
87 * hint, only one driver regulatory hint will be sent as such the
88 * secondary radios are expected to follow.
89 * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory
90 * request with all radios reporting the same regulatory domain.
91 * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling
92 * different regulatory domains requests. Expected behaviour is for
93 * an intersection to occur but each device will still use their
94 * respective regulatory requested domains. Subsequent radios will
95 * use the resulting intersection.
96 * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish
97 * this by using a custom beacon-capable regulatory domain for the first
98 * radio. All other device world roam.
99 * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory
100 * domain requests. All radios will adhere to this custom world regulatory
102 * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory
103 * domain requests. The first radio will adhere to the first custom world
104 * regulatory domain, the second one to the second custom world regulatory
105 * domain. All other devices will world roam.
106 * @HWSIM_REGTEST_STRICT_FOLLOW: Used for testing strict regulatory domain
107 * settings, only the first radio will send a regulatory domain request
108 * and use strict settings. The rest of the radios are expected to follow.
109 * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain
110 * settings. All radios will adhere to this.
111 * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory
112 * domain settings, combined with secondary driver regulatory domain
113 * settings. The first radio will get a strict regulatory domain setting
114 * using the first driver regulatory request and the second radio will use
115 * non-strict settings using the second driver regulatory request. All
116 * other devices should follow the intersection created between the
118 * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need
119 * at least 6 radios for a complete test. We will test in this order:
120 * 1 - driver custom world regulatory domain
121 * 2 - second custom world regulatory domain
122 * 3 - first driver regulatory domain request
123 * 4 - second driver regulatory domain request
124 * 5 - strict regulatory domain settings using the third driver regulatory
126 * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio
127 * regulatory requests.
