Subject: [PATCH 2/6] wifi: ath12k: Correct 6 GHz frequency value in rx status
Date: Mon, 25 Mar 2024 14:23:00 -0700 [thread overview]
Message-ID: <20240325212304.28241-3-quic_pradeepc@quicinc.com> (raw)
In-Reply-To: <20240325212304.28241-1-quic_pradeepc@quicinc.com>
The frequency in the rx status is currently being filled
incorrectly for the 6 GHz band. The channel number received is
invalid in this case, resulting in packet drops. Fix this
issue by correcting the frequency calculation.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Fixes: d889913205cf ("wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices")
