* __regulatory_hint - hint to the wireless core a regulatory domain
|
|
* @wiphy: if a driver is providing the hint this is the driver's very
|
|
* own &struct wiphy
|
|
* @alpha2: the ISO/IEC 3166 alpha2 being claimed the regulatory domain
|
|
* should be in. If @rd is set this should be NULL
|
|
* @rd: a complete regulatory domain, if passed the caller need not worry
|
|
* about freeing it
|
|
*
|
|
* The Wireless subsystem can use this function to hint to the wireless core
|
|
* what it believes should be the current regulatory domain by
|
|
* giving it an ISO/IEC 3166 alpha2 country code it knows its regulatory
|
|
* domain should be in or by providing a completely build regulatory domain.
|
|
*
|
|
* Returns -EALREADY if *a regulatory domain* has already been set. Note that
|
|
* this could be by another driver. It is safe for drivers to continue if
|
|
* -EALREADY is returned, if drivers are not capable of world roaming they
|
|
* should not register more channels than they support. Right now we only
|
|
* support listening to the first driver hint. If the driver is capable
|
|
* of world roaming but wants to respect its own EEPROM mappings for
|
|
* specific regulatory domains it should register the @reg_notifier callback
|
|
* on the &struct wiphy. Returns 0 if the hint went through fine or through an
|
|
* intersection operation. Otherwise a standard error code is returned.
