Subject: [PATCH 02/13] net: dsa: mt7530: populate supported_interfaces and
mac_capabilities
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Populate the supported interfaces and MAC capabilities for mt7530,
mt7531 and mt7621 DSA switches. Filling this in will enable phylink
to pre-check the PHY interface mode against the the supported
interfaces bitmap prior to calling the validate function, and will
eventually allow us to convert to using the generic validation.
