[PATCH net-next 1/5] net: mscc: ocelot: classify L2 mdb entries as LOCKED

From: Vladimir Oltean
Date: Wed Oct 28 2020 - 22:28:14 EST


ocelot.h says:

/* MAC table entry types.
* ENTRYTYPE_NORMAL is subject to aging.
* ENTRYTYPE_LOCKED is not subject to aging.
* ENTRYTYPE_MACv4 is not subject to aging. For IPv4 multicast.
* ENTRYTYPE_MACv6 is not subject to aging. For IPv6 multicast.
*/

We don't want the permanent entries added with 'bridge mdb' to be
subject to aging.
