Subject: [PATCH 34/39] mlxsw: spectrum_switchdev: Don't ignore deletions of learned MACs

From: Petr Machata <[email-masked]>
Date: Mon, 29 Oct 2018 14:26:14 +0000

[ Upstream commit ad0b9d94182be8356978d220c82f9837cffeb7a9 ]

Demands to remove FDB entries should be honored even if the FDB entry in
question was originally learned, and not added by the user. Therefore
ignore the added_by_user datum for SWITCHDEV_FDB_DEL_TO_DEVICE.

Fixes: 816a3bed9549 ("switchdev: Add fdb.added_by_user to switchdev notifications")
