+Subject: [PATCH] net: dsa: Include local addresses in assisted CPU port
+ learning
+
+Add local addresses (i.e. the ports' MAC addresses) to the hardware
+FDB when assisted CPU port learning is enabled.
+
+NOTE: The bridge's own MAC address is also "local". If that address is
+not shared with any port, the bridge's MAC is not be added by this
+functionality - but the following commit takes care of that case.
+
