[PATCH net-next 03/14] net: dsa: mv88e6xxx: setup ATU Learn2All
From: Vivien Didelot
Date: Thu Mar 09 2017 - 18:39:36 EST
Marvell switch chips which can be interconnected have an ATU Learn2All
feature which allows chosen ports to also learn newly added addresses.
Enable this feature and mark the DSA links as so called "Message Ports".
