- This driver is a developer testing tool that can be used to test
- IEEE 802.11 networking stack (mac80211) functionality. This is not
- needed for normal wireless LAN usage and is only for testing. See
- Documentation/networking/mac80211_hwsim for more information on how
- to use this tool.
-
- To compile this driver as a module, choose M here: the module will be
- called mac80211_hwsim. If unsure, say N.

-/**
- * 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.

+ * 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

+ * DOC: Frame transmission/registration support

+ * frames from a mac80211_hwsim radio device.
+ *
+ * This allow user space applications to decide if the frame should be
+ * dropped or not and implement a wireless medium simulator at user space.
+ *
+ * Registration is done by sending a register message to the driver and
+ * will be automatically unregistered if the user application doesn't
+ * responds to sent frames.
+ * Once registered the user application has to take responsibility of
+ * broadcasting the frames to all listening mac80211_hwsim radio
