Subject: [PATCH v1 1/9] net: add RX preprocessor support
Date: Mon, 21 Mar 2022 10:25:58 +0100 [thread overview]
Message-ID: <20220321092606.1459834-2-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20220321092606.1459834-1-o.rempel@pengutronix.de>
Add callback for optional rx_preprocessor. This is needed to add DSA
switch support and demultiplex traffic received from different switch ports.
