Subject: [PATCH net-next 2/8] net: microchip: sparx5: Improve the IP frame key match for IPv6 frames
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.
