From 2c4c3aff7362b09ec356bd9f3b7cf4a718307264 Mon Sep 17 00:00:00 2001 From: P Praneesh Date: Mon, 24 Mar 2025 11:55:18 +0530 Subject: [PATCH] wifi: ath12k: add monitor interface support on QCN9274 Currently, the monitor interface is not supported. To support the monitor interface, configure the monitor vdev state identifier, configure the HTT filter setup, subscribe the mac80211 NO_VIRTUAL_MONITOR feature, remove the VIRTUAL_MONITOR handler procedures since align to NO_VIRTUAL_MONITOR feature and prevent monitor interface to transmit packet. Therefore, add these procedures to add monitor interface support and enable the monitor interface support on the QCN9274 platform through the hardware parameter.
