Subject: via-rhine: fix VLAN receive handling regression.
From: Andrej Ota <andrej@xxxxxx>
[ Upstream commit 5f715c097965c0ad037f64393d0b95c50287775b ]
Because eth_type_trans() consumes ethernet header worth of bytes, a call
to read TCI from end of packet using rhine_rx_vlan_tag() no longer works
as it's reading from an invalid offset.
Tested to be working on PCEngines Alix board.
Fixes: 810f19bcb862 ("via-rhine: add consistent memory barrier in vlan receive code.")
