Subject: [PATCH net 1/2] mlxsw: spectrum_switchdev: Don't ignore deletions of
 learned MACs

From: Petr Machata <petrm@...lanox.com>

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")
