Instead they expect the software to set the appropriate region. +For these devices, the country code defaults to US, and the driver uses +the US CTL tables as well. +On devices bought in Europe this can lead to tx power being set too high +on the band edges, even if the cfg80211 regdomain is set correctly. +Fix this issue by taking into account the DFS region, but only when the +EEPROM regdomain is set to default. + +Signed-off-by: Felix Fietkau <nbd@openwrt.org> +--- + +--- a/drivers/net/wireless/ath/ath.h ++++ b/drivers/net/wireless/ath/ath.h +@@ -80,6 +80,7 @@ struct reg_dmn_pair_mapping { + + struct ath_regulatory { + char alpha2[2]; ++ enum nl80211_dfs_regions region; + u16 country_code; + u16 max_power_level; + u16 current_rd; +--- a/drivers/net/wireless/ath/regd.c ++++ b/drivers/net/wireless/ath/regd.c +@@ -515,6 +515,7 @@ void ath_reg_notifier_apply(struct wiphy + if (!request) + return; + ++ reg->region = request->dfs_region; + switch (request->initiator) { + case NL80211_REGDOM_SET_BY_CORE: + /* +@@ -779,6 +780,19 @@ u32 ath_regd_get_band_ctl(struct ath_reg + return SD_NO_CTL; + } + ++ if (ath_regd_get_eepromRD(reg) == CTRY_DEFAULT) { ++ switch (reg->region) { ++ case NL80211_DFS_FCC: ++ return CTL_FCC; ++ case NL80211_DFS_ETSI: ++ return CTL_ETSI; ++ case NL80211_DFS_JP: ++ return CTL_MKK; ++ default: ++ break; ++ } ++ } ++ + switch (band) { + case IEEE80211_BAND_2GHZ: + return reg->regpair->reg_2ghz_ctl; |
