77 * enum hwsim_regtest - the type of regulatory tests we offer
78 *
79 * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed,
80 * this is the default value.
81 * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory
82 * hint, only one driver regulatory hint will be sent as such the
83 * secondary radios are expected to follow.
84 * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory
85 * request with all radios reporting the same regulatory domain.
86 * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling
87 * different regulatory domains requests. Expected behaviour is for
88 * an intersection to occur but each device will still use their
89 * respective regulatory requested domains. Subsequent radios will
90 * use the resulting intersection.
91 * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish
92 * this by using a custom beacon-capable regulatory domain for the first
93 * radio. All other device world roam.
94 * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory
95 * domain requests. All radios will adhere to this custom world regulatory
96 * domain.
97 * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory
98 * domain requests. The first radio will adhere to the first custom world
99 * regulatory domain, the second one to the second custom world regulatory
100 * domain. All other devices will world roam.
101 * @HWSIM_REGTEST_STRICT_FOLLOW: Used for testing strict regulatory domain
102 * settings, only the first radio will send a regulatory domain request
103 * and use strict settings. The rest of the radios are expected to follow.
104 * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain
105 * settings. All radios will adhere to this.
106 * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory
107 * domain settings, combined with secondary driver regulatory domain
108 * settings. The first radio will get a strict regulatory domain setting
109 * using the first driver regulatory request and the second radio will use
110 * non-strict settings using the second driver regulatory request. All
111 * other devices should follow the intersection created between the
112 * first two.
113 * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need
114 * at least 6 radios for a complete test. We will test in this order:
115 * 1 - driver custom world regulatory domain
116 * 2 - second custom world regulatory domain
117 * 3 - first driver regulatory domain request
118 * 4 - second driver regulatory domain request
119 * 5 - strict regulatory domain settings using the third driver regulatory
120 * domain request
121 * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio
122 * regulatory requests.
123 *
124 * These are the different values you can use for the regtest
125 * module parameter. This is useful to help test world roaming
126 * and the driver regulatory_hint() call and combinations of these.
127 * If you want to do specific alpha2 regulatory domain tests simply
128 * use the userspace regulatory request as that will be respected as
129 * well without the need of this module parameter. This is designed
130 * only for testing the driver regulatory request, world roaming
131 * and all possible combinations.
