From 7423b64191e325681e0198f4a8ccfe66f282b95a Mon Sep 17 00:00:00 2001 From: Karthikeyan Periyasamy Date: Mon, 24 Mar 2025 11:55:17 +0530 Subject: [PATCH] wifi: ath12k: Move to NO_VIRTUAL monitor Currently, VIRTUAL monitor handling is present. In multi radio model, VIRTUAL monitor is not suitable since each radio needs a separate VIF and channel context. Therefore, switch to NO_VIRTUAL_MONITOR feature. Remove the monitor_conf_enabled flag and mac_op_config() handler as they are not need for the NO_VIRTUAL_MONITOR feature. In NO_VIRTUAL_MONITOR handling, each interface creation/deletion triggers the mac_op_add_interface() / mac_op_remove_interface() callback. Consequently, remove the monitor vdev create/delete/start/stop from the other vdev type handlers.
