From 7424edbb559036ddf63eb7c655b3305d91b12dc9 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Tue, 2 Jul 2019 07:59:17 +0200 Subject: [PATCH] Revert "r8169: improve handling VLAN tag" This reverts commit 759d095741721888b6ee51afa74e0a66ce65e974. The patch was based on a misunderstanding. As Al Viro pointed out [0] it's simply wrong on big endian. So let's revert it.
