From: Felix Fietkau Date: Wed, 22 Mar 2017 19:24:32 +0000 (+0100) Subject: ath: do not apply broken power limits with ATH_USER_REGD X-Git-Tag: v17.01.2~76 X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=a9728799bc41e68de4d50995bb4ad689784ef55e ath: do not apply broken power limits with ATH_USER_REGD If a device uses the default EEPROM code, typically only the main CTLs are valid, and they do not apply properly when switching to a different regulatory domain. If the regdomain deviates from the EEPROM one, force the world roaming regdomain to ensure that power limits are sane Signed-off-by: Felix Fietkau --- diff --git a/package/kernel/mac80211/patches/402-ath_regd_optional.patch b/package/kernel/mac80211/patches/402-ath_regd_optional.patch index 0d6d3dbdbd..c8ede7f583 100644 --- a/package/kernel/mac80211/patches/402-ath_regd_optional.patch +++ b/package/kernel/mac80211/patches/402-ath_regd_optional.patch @@ -1,6 +1,14 @@ --- a/drivers/net/wireless/ath/regd.c +++ b/drivers/net/wireless/ath/regd.c -@@ -116,6 +116,9 @@ static const struct ieee80211_regdomain +@@ -24,6 +24,7 @@ + #include "regd_common.h" + + static int __ath_regd_init(struct ath_regulatory *reg);
