Subject: [PATCH AUTOSEL 5.1 92/95] net: dsa: mv88e6xxx: fix shift of FID bits in mv88e6185_g1_vtu_loadpurge()
Date: Wed, 26 Jun 2019 20:30:17 -0400
Message-ID: <20190627003021.19867-92-sashal@kernel.org> (raw)
In-Reply-To: <20190627003021.19867-1-sashal@kernel.org>

From: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

[ 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)
