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 <akolli@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
