From 3d15f31dfdf8ef27ca2c80fb63b789d4b22d2659 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Sat, 20 Nov 2021 13:26:00 +0000 Subject: net: stmmac/xpcs: convert to pcs_validate() stmmac explicitly calls the xpcs driver to validate the ethtool linkmodes. This is no longer necessary as phylink now supports validation through a PCS method. Convert both drivers to use this new mechanism.
