ath10k_sta_statistics is used to report many info to iw wlan0 link, if it return for empty legacy and nss of arsta->txrate, then the other stats after it will not be set. It has 4 bit to set after the return: NL80211_STA_INFO_TX_FAILED NL80211_STA_INFO_RX_BITRATE NL80211_STA_INFO_TX_BITRATE NL80211_STA_INFO_TX_RETRIES This patch not effect the info of above 4 bit for all hardware, reason as below: NL80211_STA_INFO_TX_FAILED is only for htt.disable_tx_comp is true, it is for QCA6174 SDIO. NL80211_STA_INFO_RX_BITRATE and NL80211_STA_INFO_TX_BITRATE are both set in ath10k_mac_sta_get_peer_stats_info, it is only enabled for chips which supports_peer_stats_info is true in hw_params, recently only for QCA6174 SDIO, NL80211_STA_INFO_TX_BITRATE is set again in function ath10k_mac_sta_get_peer_stats_info because the value which parsed from arsta->tx_rate_code and arsta->tx_bitrate_kbps is correct for QCA6174 SDIO and PCIe, and the value arsta->txrate is not correct for QCA6174 SDIO and PCIe, so it need to set again with the correct value. NL80211_STA_INFO_TX_RETRIES is use value of arsta->tx_retries, it is set in ath10k_update_per_peer_tx_stats, which accumulate the retry_pkts in HTT message from firmware, if the chips not support this feature, then it is always 0 after accumulate, then iw wlan0 station dump always show 0 for retry count. If not set NL80211_STA_INFO_TX_RETRIES here, then it is still 0, so the result is same, then set NL80211_STA_INFO_TX_RETRIES has no effect.
