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