[PATCH AUTOSEL 4.14 34/35] net: dsa: mv88e6xxx: fix shift of FID bits in mv88e6185_g1_vtu_loadpurge()

From: Sasha Levin <sashal@kernel.org>
Date: 2019-06-27 00:41:27
Also in: lkml, stable
Subsystem: marvell 88e6xxx ethernet switch fabric driver, networking drivers, networking [dsa], the rest · Maintainers: Andrew Lunn, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Vladimir Oltean, Linus Torvalds

From: Rasmus Villemoes <redacted>

[ Upstream commit 48620e341659f6e4b978ec229f6944dabe6df709 ]

The comment is correct, but the code ends up moving the bits four
places too far, into the VTUOp field.

Fixes: 11ea809f1a74 (net: dsa: mv88e6xxx: support 256 databases)
