Subject: [PATCH] wifi: ath12k: add display tx and rx bitrate for 11be
Date: Wed, 3 Jan 2024 22:22:02 -0500
Message-ID: <20240104032202.19472-1-quic_lingbok@quicinc.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Content-Type: text/plain

When AP is in 11be state, STA's tx/rx bitrate display error value using iw
dev wlan command.

In ath12k_dp_tx_update_txcompl() function, not handle the case when
pkt_type is equal to HAL_TX_RATE_STATS_PKT_TYPE_11BE, so add a else if
statement to handle this situation.

In ath12k_dp_rx_h_rate function, not handle the case when pkt_type is equal
to RX_MSDU_START_PKT_TYPE_11BE, so add a case statement to handle this
situation.

After that, "iw dev xxx station dump" show the correct tx bitrate such as:
tx bitrate: 1441.1 MBit/s 80MHz EHT-MCS 13 EHT-NSS 2 EHT-GI 0
rx bitrate: 1441.1 MBit/s 80MHz EHT-MCS 9 EHT-NSS 3 EHT-GI 0

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
