NAME

       regulatory.bin, regulatory.db - The Linux wireless regulatory database

Description
       regulatory.bin and regulatory.db are the files used by the Linux wireless subsystem to keep its regulatory database information.

       regulatory.bin is read by crda upon the Linux kernel's request for regulatory information for a specific ISO / IEC 3166 alpha2 country
       code.

       regulatory.db is a newer, extensible database format which (since Linux 4.15) is read by the kernel directly as a firmware file.

       The regulatory database is kept in a small binary format for size and code efficiency. The regulatory.bin file can be parsed and read in
       human format by using the regdbdump command. The regulatory database files should be updated upon regulatory changes or corrections.

Upkeeping
       The regulatory database is maintained by the community as such you are encouraged to send any corrections or updates to the linux-wireless
       and wireless-regdb mailing lists: linux-wireless@vger.kernel.org and wireless-regdb@lists.infradead.org

NAME

       regulatory_hint - driver hint to the wireless core a regulatory domain

SYNOPSIS

       int regulatory_hint(struct wiphy * wiphy, const char * alpha2);

ARGUMENTS

       wiphy
	   the wireless device giving the hint (used only for reporting conflicts)

       alpha2
	   the ISO/IEC 3166 alpha2 the driver claims its regulatory domain should be in. If rd is set this should be NULL. Note that if you set
	   this to NULL you should still set rd->alpha2 to some accepted alpha2.

DESCRIPTION

       Wireless drivers 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. If
       the driver provides an ISO/IEC 3166 alpha2 userspace will be queried for a regulatory domain structure for the respective country.

       The wiphy must have been registered to cfg80211 prior to this call. For cfg80211 drivers this means you must first use wiphy_register, for
       mac80211 drivers you must first use ieee80211_register_hw.

       Drivers should check the return value, its possible you can get an -ENOMEM.

RETURN

       0 on success. -ENOMEM.
