Subject: [PATCH 1/2] wifi: ath12k: register EHT mesh capabilities
Date:   Fri, 13 Oct 2023 12:30:07 +0530
Message-Id: <20231013070007.25597-3-quic_rgnanase@quicinc.com>
In-Reply-To: <20231013070007.25597-1-quic_rgnanase@quicinc.com>
References: <20231013070007.25597-1-quic_rgnanase@quicinc.com>
Precedence: bulk

The capabilities for the EHT mesh are generated from the capabilities
reported by the firmware. But the firmware only reports the overall
capabilities and not the one which are specific for mesh.

Capabilities which requires infrastructure setup with a main STA(AP)
controlling operations are not needed for mesh and hence remove these
capabilities from the list.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0-02903-QCAHKSWPL_SILICONZ-1
