Subject[PATCH 4.19 14/24] mlxsw: spectrum_switchdev: Dont ignore deletions of learned MACs
Date
4.19-stable review patch.  If anyone has any objections, please let me know.

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

From: Petr Machata <petrm@mellanox.com>

[ 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")
