Subject: [PATCH net-next 2/8] net: microchip: sparx5: Improve the IP frame key match for IPv6 frames
Date: Fri, 27 Jan 2023 14:08:24 +0100	[thread overview]
Message-ID: <20230127130830.1481526-3-steen.hegelund@microchip.com> (raw)
In-Reply-To: <20230127130830.1481526-1-steen.hegelund@microchip.com>

This ensures that it will be possible for a VCAP rule to distinguish IPv6
frames from non-IP frames, as the IS0 keyset usually selected for the IPv6
traffic class in (7TUPLE) does not offer a key that specifies IPv6
directly: only non-IPv4.

The IP_SNAP key ensures that we select (at least) IP frames.
