From 4cc02c7c14944b16020c8da44572b3c5d189d386 Mon Sep 17 00:00:00 2001 From: Wen Gong Date: Mon, 27 Apr 2020 16:04:16 +0800 Subject: [PATCH] ath10k: correct tx bitrate of iw for SDIO For legacy mode, tx bitrate not show correct sometimes, for example: iw wlan0 link Connected to 8c:21:0a:b3:5a:64 (on wlan0) SSID: tplinkgw freq: 2462 RX: 19672 bytes (184 packets) TX: 9851 bytes (87 packets) signal: -51 dBm rx bitrate: 54.0 MBit/s tx bitrate: 2.8 MBit/s This patch use the tx bitrate info from WMI_TLV_PEER_STATS_INFO_EVENTID report from firmware, and tx bitrate show correct. iw wlan0 link Connected to 8c:21:0a:b3:5a:64 (on wlan0) SSID: tplinkgw freq: 2462 RX: 13973 bytes (120 packets) TX: 6737 bytes (57 packets) signal: -52 dBm rx bitrate: 54.0 MBit/s tx bitrate: 54.0 MBit/s This patch only effect SDIO chip, ath10k_mac_sta_get_peer_stats_info has check for bitrate_statistics of hw_params, it is enabled only for "qca6174 hw3.2 sdio". Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.
