Tx bitrate got by command 'iw wlan0 link' is incorrect.
These 2 patches will fix the issue.
Changes from v1:
[PATCH v2] ath10k: correct legacy rate in tx stats
Remove wmi ops for getting legacy rate, instead, update the ratecode got from
PPDU stats, to align with the existing tx rate processing.
Yu Wang (2):
ath10k: add ppdu stats support for QCA6174/QCA9377

When QCA6174/QCA9377 working in station mode, after connected
to AP, tx bitrate is always '1.0 MBit/s' in output of command
'iw wlan0 link'.
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.

* [PATCH v2 2/2] ath10k: correct legacy rate in tx stats

From: Yu Wang <yyuwang@codeaurora.org>
When working in station mode, after connected to a legacy
AP, 11g only, for example, the tx bitrate is incorrect in
output of command 'iw wlan0 link'.
That's because the legacy tx bitrate value reported by
firmware is not well handled:
For QCA6174, the value represents rate index, but treated
as a real rate;
For QCA9888, the value is real rate, with unit 'Mbps', but
treated as '100kbps'.
To fix this issue:
1. Translate the rate index to real rate for QCA6174;
2. Translate the rate from 'Mbps' to 'kbps' for QCA9888.
Tested with:
QCA6174 PCIe with firmware WLAN.RM.4.4.1.c3-00031.
QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.
QCA9888 PCIe with firmware 10.4-3.9.0.2-00040.

When QCA6174/QCA9377 working in station mode, after connected
to AP, tx bitrate is always '1.0 MBit/s' in output of command
'iw wlan0 link'.
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.

When QCA6174/QCA9377 working in station mode, after connected
to AP, tx bitrate is always '1.0 MBit/s' in output of command
'iw wlan0 link'.
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.
