From 2d3a7384b9c8ea0b640747176cc01af64cf722ec Mon Sep 17 00:00:00 2001 From: Raj Kumar Bhagat Date: Mon, 29 Jan 2024 12:27:24 +0530 Subject: [PATCH] wifi: ath12k: disable QMI PHY capability learn in split-phy QCN9274 QMI PHY capability learn is used to get PHY count information to support single/multi link operation (SLO/MLO) configuration. The QCN9274 dualmac firmware currently do not support SLO/MLO, if two PHYs are within the same chip. Due to this firmware crashes in split-phy QCN9274, while bringing up AP with MLO parameter enabled in QMI host capability request message. The QMI PHY capability learn is not required for split-phy QCN9274, if SLO/MLO is not supported within the same chip. Hence, disable QMI PHY capability learn support in split-phy QCN9274.
