For SDIO chip, its rx indication is struct htt_rx_indication_hl, which does not include the bitrate info as well as PCIe, for PCIe, it use function ath10k_htt_rx_h_rates to parse the bitrate info in struct rx_ppdu_start and then report it to mac80211 via ieee80211_rx_status. SDIO does not have the same info as PCIe, then iw command can not get the rx bitrate by "iw wlan0 station dump". for example, it always show 6.0 MBit/s localhost ~ # iw wlan0 link Connected to 3c:28:6d:96:fd:69 (on wlan0) SSID: kukui_test freq: 5180 RX: 111800 bytes (595 packets) TX: 35419 bytes (202 packets) signal: -41 dBm rx bitrate: 6.0 MBit/s This patch is to send WMI_TLV_REQUEST_PEER_STATS_INFO_CMDID to firmware for ath10k_sta_statistics and save the rx bitrate for WMI event WMI_TLV_PEER_STATS_INFO_EVENTID. This patch only effect SDIO chip, ath10k_mac_sta_get_peer_stats_info has check for bitrate_statistics of hw_params, this patch only enable it for "qca6174 hw3.2 sdio".
