From a1da54bcd664fc27169386db966575675ac3ccb0 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Mon, 11 Apr 2022 10:46:01 +0100 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.
