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; diff --git a/package/kernel/mac80211/patches/400-ath_move_debug_code.patch b/package/kernel/mac80211/patches/400-ath_move_debug_code.patch index ccd4a3e501..229fc46128 100644 --- a/package/kernel/mac80211/patches/400-ath_move_debug_code.patch +++ b/package/kernel/mac80211/patches/400-ath_move_debug_code.patch @@ -14,7 +14,7 @@ ccflags-y += -D__CHECK_ENDIAN__ --- a/drivers/net/wireless/ath/ath.h +++ b/drivers/net/wireless/ath/ath.h -@@ -300,13 +300,6 @@ void _ath_dbg(struct ath_common *common, +@@ -301,13 +301,6 @@ void _ath_dbg(struct ath_common *common, #endif /* CPTCFG_ATH_DEBUG */ /** Returns string describing opmode, or NULL if unknown mode. */ diff --git a/package/kernel/mac80211/patches/402-ath_regd_optional.patch b/package/kernel/mac80211/patches/402-ath_regd_optional.patch index 42260fcf86..786b39ce00 100644 --- a/package/kernel/mac80211/patches/402-ath_regd_optional.patch +++ b/package/kernel/mac80211/patches/402-ath_regd_optional.patch @@ -33,7 +33,7 @@ if (!wiphy->bands[IEEE80211_BAND_5GHZ]) return; -@@ -631,6 +643,10 @@ ath_regd_init_wiphy(struct ath_regulator +@@ -632,6 +644,10 @@ ath_regd_init_wiphy(struct ath_regulator { const struct ieee80211_regdomain *regd; diff --git a/package/kernel/mac80211/patches/512-ath9k_channelbw_debugfs.patch b/package/kernel/mac80211/patches/512-ath9k_channelbw_debugfs.patch index 24671ca12e..fae3102206 100644 --- a/package/kernel/mac80211/patches/512-ath9k_channelbw_debugfs.patch +++ b/package/kernel/mac80211/patches/512-ath9k_channelbw_debugfs.patch @@ -64,7 +64,7 @@ debugfs_create_file("interrupt", S_IRUSR, sc->debug.debugfs_phy, sc, --- a/drivers/net/wireless/ath/ath.h +++ b/drivers/net/wireless/ath/ath.h -@@ -141,6 +141,7 @@ struct ath_common { +@@ -142,6 +142,7 @@ struct ath_common { int debug_mask; enum ath_device_state state; unsigned long op_flags; |
