From a904417fc8761b78d46342d13a6fd08f4beb7075 Mon Sep 17 00:00:00 2001 From: Anilkumar Kolli Date: Tue, 4 Sep 2018 12:15:15 +0530 Subject: [PATCH] ath10k: add extended per sta tx statistics support This patch adds per station tx statistics support. Per station tx stats include - pkts/bytes transmitted at all possible rates(mcs/nss/bw/gi). - ACK fails count - ampdu bytes/pkts transmitted at all possible rates(mcs/nss/bw/gi). - BA fails count Tested on QCA9984/QCA4019/QCA988x Firmware: 10.4-3.5.3-00057 10.2.4-1.0-00037 Signed-off-by: Anilkumar Kolli Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath10k/core.h | 31 +++++++++ drivers/net/wireless/ath/ath10k/htt_rx.c | 109 +++++++++++++++++++++++++++++++ drivers/net/wireless/ath/ath10k/mac.c | 10 +++ drivers/net/wireless/ath/ath10k/wmi.h | 13 ++-- 4 files changed, 159 insertions(+), 4 deletions(-) diff --git a/drivers/net/wireless/ath/ath10k/core.h b/drivers/net/wireless/ath/ath10k/core.h index 999a6d2ef578..27df8ac26254 100644 --- a/drivers/net/wireless/ath/ath10k/core.h +++ b/drivers/net/wireless/ath/ath10k/core.h @@ -461,6 +461,36 @@ struct ath10k_sta_tid_stats { unsigned long int rx_pkt_amsdu[ATH10K_AMSDU_SUBFRM_NUM_MAX];
