4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andrej Ota <[email protected]>

[ 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.")
