Subject: via-rhine: fix VLAN priority field (PCP, IEEE 802.1p)
From: Roger Luethi <rl@xxxxxxxxxxx>
[ Upstream commit 207070f5221e2a901d56a49df9cde47d9b716cd7 ]
Outgoing packets sent by via-rhine have their VLAN PCP field off by one
(when hardware acceleration is enabled). The TX descriptor expects only VID
and PCP (without a CFI/DEI bit).
Peter Boström noticed and reported the bug.
