79 * enum hwsim_regtest - the type of regulatory tests we offer
80 *
81 * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed,
82 * this is the default value.
83 * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory
84 * hint, only one driver regulatory hint will be sent as such the
85 * secondary radios are expected to follow.
86 * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory
87 * request with all radios reporting the same regulatory domain.
88 * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling
89 * different regulatory domains requests. Expected behaviour is for
90 * an intersection to occur but each device will still use their
91 * respective regulatory requested domains. Subsequent radios will
92 * use the resulting intersection.
93 * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish
94 * this by using a custom beacon-capable regulatory domain for the first
95 * radio. All other device world roam.
96 * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory
97 * domain requests. All radios will adhere to this custom world regulatory
98 * domain.
99 * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory
100 * domain requests. The first radio will adhere to the first custom world
101 * regulatory domain, the second one to the second custom world regulatory
102 * domain. All other devices will world roam.
103 * @HWSIM_REGTEST_STRICT_FOLLOW: Used for testing strict regulatory domain
104 * settings, only the first radio will send a regulatory domain request
105 * and use strict settings. The rest of the radios are expected to follow.
106 * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain
107 * settings. All radios will adhere to this.
108 * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory
109 * domain settings, combined with secondary driver regulatory domain
110 * settings. The first radio will get a strict regulatory domain setting
111 * using the first driver regulatory request and the second radio will use
112 * non-strict settings using the second driver regulatory request. All
113 * other devices should follow the intersection created between the
114 * first two.
115 * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need
116 * at least 6 radios for a complete test. We will test in this order:
117 * 1 - driver custom world regulatory domain
118 * 2 - second custom world regulatory domain
119 * 3 - first driver regulatory domain request
120 * 4 - second driver regulatory domain request
121 * 5 - strict regulatory domain settings using the third driver regulatory
122 * domain request
123 * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio
124 * regulatory requests.
125 *
126 * These are the different values you can use for the regtest
127 * module parameter. This is useful to help test world roaming
128 * and the driver regulatory_hint() call and combinations of these.
129 * If you want to do specific alpha2 regulatory domain tests simply
130 * use the userspace regulatory request as that will be respected as
131 * well without the need of this module parameter. This is designed
132 * only for testing the driver regulatory request, world roaming
133 * and all possible combinations.
