Vladimir Oltean says:

====================
Allow unknown unicast traffic to CPU for Felix DSA

This is the continuation of the previous "[PATCH net-next] net: mscc:
ocelot: Workaround to allow traffic to CPU in standalone mode":

https://www.spinics.net/lists/netdev/msg631067.html

Following the feedback received from Allan Nielsen, the Ocelot and Felix
drivers were made to use the CPU port module in the same way (patch 1),
and Felix was made to additionally allow unknown unicast frames towards
the CPU port module (patch 2).
