+Subject: [PATCH] net: mscc: ocelot: make phy_mode a member of the common
+ struct ocelot_port
+
+The Ocelot switchdev driver and the Felix DSA one need it for different
+reasons. Felix (or at least the VSC9959 instantiation in NXP LS1028A) is
+integrated with the traditional NXP Layerscape PCS design which does not
+support runtime configuration of SerDes protocol. So it needs to
+pre-validate the phy-mode from the device tree and prevent PHYLINK from
+attempting to change it. For this, it needs to cache it in a private
+variable.
