From e3f6719e2269868ca129b05da50cd55786848954 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Mon, 11 Apr 2022 10:46:06 +0100 Subject: [PATCH 03/13] net: dsa: mt7530: remove interface checks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As phylink checks the interface mode against the supported_interfaces bitmap, we no longer need to validate the interface mode, nor handle PHY_INTERFACE_MODE_NA in the validation function. Remove these to simplify the implementation.
