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 <akolli@codeaurora.org> --- drivers/net/wireless/ath/ath10k/core.h | 31 +++++++++ drivers/net/wireless/ath/ath10k/htt_rx.c | 109 ++++++++++++++++++++++++++++++ drivers/net/wireless/ath/ath10k/mac.c | 7 ++ drivers/net/wireless/ath/ath10k/wmi.h | 13 ++-- 4 files changed, 156 insertions(+), 4 deletions(-)
