From b993046234fc3110f5ca3eb561492f8072ccc689 Mon Sep 17 00:00:00 2001 From: Chih-Kang Chang Date: Thu, 25 Jun 2026 14:15:40 +0800 Subject: [PATCH] wifi: rtw89: disable sniffer mode in RX filter when initialization for Wi-Fi 7 chips Sniffer mode is enabled by default in the RX filter on Wi-Fi 7 chips, which causes all packets to be received regardless of the ADDR_CAM lookup result. This may result in unexpected packets being received. Therefore, disable it by default.
