+ * @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
+ * @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
