Subject: [PATCH rtw-next 05/10] wifi: rtw89: disable sniffer mode in RX filter when initialization for Wi-Fi 7 chips
Date: Thu, 25 Jun 2026 14:15:40 +0800	[thread overview]
Message-ID: <20260625061545.44808-6-pkshih@realtek.com> (raw)
In-Reply-To: <20260625061545.44808-1-pkshih@realtek.com>

From: Chih-Kang Chang <gary.chang@realtek.com>

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.
