Subject: [RFC PATCH net-next v3 13/15] net: dsa: mt7530: add support for 10G
 link modes for CPU port
Message-ID: <495231a9d84159878116c2cb181537da674edc27.1680105013.git.daniel@makrotopia.org>

Precedence: bulk

The built-in switch of the MT7988 SoC is internally connected using
a stateless 10G link. Add support for 10G interface modes to silence
a warning otherwise occurring when the switch driver is setup.
