From 1b311aab3141bbea5667be4517e2599e6235cca0 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 5 Feb 2022 18:52:36 +0100 Subject: Revert "kernel: backport MediaTek Ethernet PHY driver" This reverts commit 8b4cba53a9402f44da2dced4a78ca065b15dca94. This broke the mt7530 on Linksys e8450 (mt7622) for me.
