From: Vladimir Oltean <vladimir.oltean@xxxxxxx> This series tries to make DSA behave a bit more sanely when bridged with "foreign" (non-DSA) interfaces and source address learning is not supported on the hardware CPU port (which would make things work more seamlessly without software intervention). When a station A connected to a DSA switch port needs to talk to another station B connected to a non-DSA port through the Linux bridge, DSA must explicitly add a route for station B towards its CPU port.
