Subject: [PATCH 08/10] wifi: ath12k: clean up 80P80 support
Date: Mon, 25 Mar 2024 13:10:29 -0700
Message-ID: <20240325201031.10837-9-quic_pradeepc@quicinc.com>
In-Reply-To: <20240325201031.10837-1-quic_pradeepc@quicinc.com>

Clean up unused 80P80 references as hardware does not support
it. This is applicable to both QCN9274 and WCN7850.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
