From d33bc467e8325be66b7209250e9829d199034ffe Mon Sep 17 00:00:00 2001 From: Rameshkumar Sundaram Date: Wed, 11 Dec 2024 17:43:58 +0200 Subject: [PATCH] wifi: ath12k: advertise MLO support and capabilities Now everything in ath12k is in place and we can enable Multi-Link Operation (MLO) in the driver. For now it's only enabled for QCN9274 with firmware having ATH12K_FW_FEATURE_MLO feature bit set.
