Subject: [PATCH AUTOSEL 4.19 90/97] mscc: Configured MAC entries should be locked.

From: "Allan W. Nielsen" <allan.nielsen@...rochip.com>

[ Upstream commit 8fd1a4affbdafda592f80cd01bf7a382a5ff2fe8 ]

The MAC table in Ocelot supports auto aging (normal) and static entries.
MAC entries that is manually configured should be static and not subject
to aging.
