/**
* struct regulatory_request - used to keep track of regulatory requests
*
* @wiphy_idx: this is set if this request's initiator is
* %REGDOM_SET_BY_COUNTRY_IE or %REGDOM_SET_BY_DRIVER. This
* can be used by the wireless core to deal with conflicts
* and potentially inform users of which devices specifically
* cased the conflicts.
* @initiator: indicates who sent this request, could be any of
* of those set in nl80211_reg_initiator (%NL80211_REGDOM_SET_BY_*)
* @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
