+Subject: [PATCH] net: dsa: be louder when a non-legacy FDB operation fails
+
+The dev_close() call was added in commit c9eb3e0f8701 ("net: dsa: Add
+support for learning FDB through notification") "to indicate inconsistent
+situation" when we could not delete an FDB entry from the port.
+
+bridge fdb del d8:58:d7:00:ca:6d dev swp0 self master
+
+It is a bit drastic and at the same time not helpful if the above fails
+to only print with netdev_dbg log level, but on the other hand to bring
+the interface down.
+
+So increase the verbosity of the error message, and drop dev_close().
