Subject: [PATCH net-next 2/9] net: dsa: mt7530: populate supported_interfaces and mac_capabilities
Date: Wed, 06 Apr 2022 11:48:42 +0100	[thread overview]
Message-ID: <E1nc3DO-004hpp-23@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <Yk1iHCy4fqvxsvu0@shell.armlinux.org.uk>

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.
