73  * enum hwsim_regtest - the type of regulatory tests we offer
74  *
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.
83  *
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
101  * 	domain.
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
117  *	first two.
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
125  * 	    domain request
126  * 	6 and on - should follow the intersection of the 3rd, 4rth and 5th radio
127  * 	           regulatory requests.
