REGULATORY_HINT(9) Regulatory enforcement infrast REGULATORY_HINT(9)NAMEregulatory_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.
