Subject: [PATCH net-next 01/10] net: microchip: sparx5: Discard frames with SMAC multicast addresses
Date: Mon, 13 Feb 2023 10:24:17 +0100 [thread overview]
Message-ID: <20230213092426.1331379-2-steen.hegelund@microchip.com> (raw)
In-Reply-To: <20230213092426.1331379-1-steen.hegelund@microchip.com>
A valid frame should never use a multicast address as its source MAC
address, so discard these invalid frames.
