73 * enum hwsim_regtest - the type of regulatory tests we offer
74 *
4a5af9c2
LR		 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.
25985edc 87 * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish
4a5af9c2
LR		 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.
e83adb18 97 * @HWSIM_REGTEST_STRICT_FOLLOW: Used for testing strict regulatory domain
4a5af9c2
LR		 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.
c9394c82
JB		 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.
