mac80211_hwsim: remove regtest for now
Browse files Browse the repository at this point in the history 
The regtest thing worked based on the radio loop, but with
more dynamic radio registration that loop won't really exist
as is. We can add it back later with proper dynamic code.

/**
* enum hwsim_regtest - the type of regulatory tests we offer
*
* These are the different values you can use for the regtest
* module parameter. This is useful to help test world roaming
* and the driver regulatory_hint() call and combinations of these.
* If you want to do specific alpha2 regulatory domain tests simply
* use the userspace regulatory request as that will be respected as
* well without the need of this module parameter. This is designed
* only for testing the driver regulatory request, world roaming
* and all possible combinations.
*
* @HWSIM_REGTEST_DISABLED: No regulatory tests are performed,
* this is the default value.
* @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory
* hint, only one driver regulatory hint will be sent as such the
* secondary radios are expected to follow.
* @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory
* request with all radios reporting the same regulatory domain.
* @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling
* different regulatory domains requests. Expected behaviour is for
* an intersection to occur but each device will still use their
* respective regulatory requested domains. Subsequent radios will
* use the resulting intersection.
* @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish
* this by using a custom beacon-capable regulatory domain for the first
* radio. All other device world roam.
* @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory
* domain requests. All radios will adhere to this custom world regulatory
* domain.
* @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory
* domain requests. The first radio will adhere to the first custom world
* regulatory domain, the second one to the second custom world regulatory
* domain. All other devices will world roam.
* @HWSIM_REGTEST_STRICT_FOLLOW_: Used for testing strict regulatory domain
* settings, only the first radio will send a regulatory domain request
* and use strict settings. The rest of the radios are expected to follow.
* @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain
* settings. All radios will adhere to this.
* @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory
* domain settings, combined with secondary driver regulatory domain
* settings. The first radio will get a strict regulatory domain setting
* using the first driver regulatory request and the second radio will use
* non-strict settings using the second driver regulatory request. All
* other devices should follow the intersection created between the
* first two.
* @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need
* at least 6 radios for a complete test. We will test in this order:
* 1 - driver custom world regulatory domain
* 2 - second custom world regulatory domain
* 3 - first driver regulatory domain request
* 4 - second driver regulatory domain request
* 5 - strict regulatory domain settings using the third driver regulatory
* domain request
* 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio
* regulatory requests.
