That's because the parameters to calculate the tx bitrate are not well updated for QCA6174/QCA9377. To fix this issue: 1. Add processing for HTT_T2H_MSG_TYPE_PPDU_STATS_IND which includes the peer tx stats; 2. Map WMI_TLV_SERVICE_PEER_STATS_INFO to WMI_SERVICE_PEER_STATS to enable the feature. Tested with QCA6174 PCIe with firmware WLAN.RM.4.4.1.c3-00031. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.
