|
* @alpha2: the ISO / IEC 3166 alpha2 country code of the requested

* regulatory domain. We have a few special codes:
|
|
* 00 - World regulatory domain
|
|
* 99 - built by driver but a specific alpha2 cannot be determined
|
|
* 98 - result of an intersection between two regulatory domains
|
|
* 97 - regulatory domain has not yet been configured
|
|
* @intersect: indicates whether the wireless core should intersect
|
|
* the requested regulatory domain with the presently set regulatory
|
|
* domain.
|
|
* @country_ie_checksum: checksum of the last processed and accepted
|
|
* country IE
|
|
* @country_ie_env: lets us know if the AP is telling us we are outdoor,
|
|
* indoor, or if it doesn't matter
|
|
* @list: used to insert into the reg_requests_list linked list
