From 0f8a2b7772f75d155c95ce3d023b81ad911234c9 Mon Sep 17 00:00:00 2001 From: Mohammed Shafi Shajakhan Date: Fri, 13 Jan 2017 16:00:03 +0530 Subject: [PATCH] ath10k: fix per station tx bit rate reporting Not clearing the previous tx bit rate status results in a ambigous tx bit rate reporting to mac80211/cfg80211, for example the previous bit rate status would have been marked as legacy rate , while the current rate would have been an HT/VHT rate with the tx bit rate flags set and this results in exporting tx bitrate as legacy rate but with HT/VHT rate flags set, fix this by clearing the tx bitrate status for each event. This also fixes the below warning when we do: iw dev wlan#N station dump WARNING: net/wireless/util.c:1222 cfg80211 [] (warn_slowpath_null) from [] (cfg80211_calculate_bitrate+0x110/0x1f4 [cfg80211]) [] (cfg80211_calculate_bitrate [cfg80211]) from [] (nl80211_put_sta_rate+0x44/0x1dc [cfg80211]) [] (nl80211_put_sta_rate [cfg80211]) from [] (nl80211_set_interface+0x724/0xd70 [cfg80211]) [] (nl80211_set_interface [cfg80211]) from [] (nl80211_dump_station+0xdc/0x100 [cfg80211]) [] (nl80211_dump_station [cfg80211]) Fixes: cec17c382140 ("ath10k: add per peer htt tx stats support for 10.4") Signed-off-by: Mohammed Shafi Shajakhan Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath10k/htt_rx.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/net/wireless/ath/ath10k/htt_rx.c b/drivers/net/wireless/ath/ath10k/htt_rx.c index 4105005dcdfe..12e67c46ea0a 100644 --- a/drivers/net/wireless/ath/ath10k/htt_rx.c +++ b/drivers/net/wireless/ath/ath10k/htt_rx.c @@ -2236,6 +2236,8 @@ ath10k_update_per_peer_tx_stats(struct ath10k *ar, return; } + memset(&arsta->txrate, 0, sizeof(arsta->txrate)); + if (txrate.flags == WMI_RATE_PREAMBLE_CCK || txrate.flags == WMI_RATE_PREAMBLE_OFDM) { rate = ATH10K_HW_LEGACY_RATE(peer_stats->ratecode); -- 2.30.2
