From 9891fbd9d8ec1710215b3c1ce1a5e9b3f33b5c1f Mon Sep 17 00:00:00 2001 From: Arulanbu Balusamy Date: Tue, 12 Aug 2025 16:47:07 +0530 Subject: [PATCH] wifi: ath12k: Add support to handle reason inactivity STA kickout event for QCN9274/IPQ5332 Currently, when the non-AP STA connected to the AP STA, and the AP STA goes down or becomes inactive without indication, firmware detects the beacon miss and sends the WMI event WMI_PEER_STA_KICKOUT_EVENTID with reason as INACTIVITY. The host driver handles this event as low ACK and reports it to the mac80211 driver. However, the expectation is that non-AP STA should be disconnected from AP STA instantly once it receives the STA kickout event with reason of inactivity. Trigger a disconnect from AP STA through beacon miss handling upon receiving non-AP STA peer kickout event with reason code inactivity. Replace the helper function ath12k_mac_get_ar_by_vdev_id() with ath12k_mac_get_arvif_by_vdev_id() due to the following reasons. 1. Check the station VIF type for handling the beacon miss. 2. Retrieve the proper ar from the arvif by checking the vdev_id with vdev_map and link_map lookup which is needed for the MLO case in the following patch.
