DSA is able to install FDB entries towards the CPU port for addresses which were dynamically learnt by the software bridge on foreign interfaces that are in the same bridge with a DSA switch interface. Since this behavior is opportunistic, it is guarded by the "assisted_learning_on_cpu_port" property which can be enabled by drivers and is not done automatically (since certain switches may support address learning of packets coming from the CPU port). But if those FDB entries added on the foreign interfaces are static (added by the user) instead of dynamically learnt, currently DSA does not do anything (and arguably it should). Because static FDB entries are not supposed to move on their own, there is no downside in reusing the "assisted_learning_on_cpu_port" logic to sync static FDB entries to the DSA CPU port unconditionally, even if assisted_learning_on_cpu_port is not requested by the driver. For example, this situation: br0 / \ swp0 dummy0 $ bridge fdb add 02:00:de:ad:00:01 dev dummy0 vlan 1 master static Results in DSA adding an entry in the hardware FDB, pointing this address towards the CPU port. The same is true for entries added to the bridge itself, e.g: $ bridge fdb add 02:00:de:ad:00:01 dev br0 vlan 1 self local (except that right now, DSA still ignores 'local' FDB entries, this will be changed in a later patch) Signed-off-by: Tobias Waldekranz <tobias@waldekranz.com> Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.
