4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Mohammed Shafi Shajakhan <mohammed@xxxxxxxxxxxxxxxx> commit fcf7cf1551cae54e747a771f5808240f2a37708f upstream. This partially reverts 'commit 2cdce425aa33 ("ath10k: Fix broken NULL func data frame status for 10.4")' Unfortunately this breaks sending NULL func and the existing issue of obtaining proper tx status for NULL function will be fixed. Also update the comments for feature flag added to be useless and not working Fixes: 2cdce425aa33 "ath10k: Fix broken NULL func data frame status for 10.4" Signed-off-by: Mohammed Shafi Shajakhan <mohammed@xxxxxxxxxxxxxxxx> Signed-off-by: Kalle Valo <kvalo@xxxxxxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/net/wireless/ath/ath10k/core.h | 6 ++---- drivers/net/wireless/ath/ath10k/mac.c | 2 -- 2 files changed, 2 insertions(+), 6 deletions(-) --- a/drivers/net/wireless/ath/ath10k/core.h +++ b/drivers/net/wireless/ath/ath10k/core.h @@ -557,10 +557,8 @@ enum ath10k_fw_features { */ ATH10K_FW_FEATURE_BTCOEX_PARAM = 14, - /* Older firmware with HTT delivers incorrect tx status for null func - * frames to driver, but this fixed in 10.2 and 10.4 firmware versions. - * Also this workaround results in reporting of incorrect null func - * status for 10.4.
