[Bridge] [RFC PATCH net-next 2/5] net: dsa: propagate flags down towards drivers
...u_port feature ("if (switchdev_fdb_is_dynamically_learned(fdb_info))"). The reason being that a "dynamically learned" FDB entry (defined as this): static inline bool switchdev_fdb_is_dynamically_learned(const struct switchdev_notifier_fdb_info *fdb_info) { return !fdb_info->added_by_user && !fdb_info->is_local; } is also dynamic in the DSA_FDB_FLAG_DYNAMIC sense. But we install a static FDB entry for it on the CPU port. And in your follow-up patch 3/5, you make all drivers except mv88e6xxx ignore all DSA_FDB_FLAG_DYNAMIC entries (including the ones snooped from addre...

[Bridge] [PATCH v2 net-next 2/6] net: dsa: propagate flags down towards drivers
...you have a suggestion, feel free. Didn't I explain what I would do from the first reply on this thread? https://patchwork.kernel.org/project/netdevbpf/patch/20230318141010.513424-3-netdev at kapio-technology.com/#25270613 As a bug fix, stop reporting to switchdev those FDB entries with BR_FDB_ADDED_BY_USER && !BR_FDB_STATIC. Then, after "net" is merged into "net-next" next Thursday (the ship has sailed for today), add "bool static" to the switchdev notifier info, and make all switchdev drivers (everywhere where a SWITCHDEV_FDB_ADD_TO_DEVICE handler appears) ign...

Okay, so this will require a new function in the DSA layer that sets which flags are supported and...

[Bridge] [PATCH net] net: bridge: switchdev: don't notify FDB entries with "master dynamic"
There is a structural problem in switchdev, where the flag bits in struct switchdev_notifier_fdb_info (added_by_user, is_local etc) only represent a simplified / denatured view of what's in struct net_bridge_fdb_entry :: flags (BR_FDB_ADDED_BY_USER, BR_FDB_LOCAL etc). Each time we want to pass more information about struct net_bridge_fdb_entry :: flags to struct switchdev_notifier_fdb_info (here, BR_FDB_STA...
