Link to patch? I don't see any SWITCHDEV_FDB_ADD_TO_BRIDGE call in either the v1: https://lore.kernel.org/netdev/20230130173429.3577450-6-netdev@xxxxxxxxxxxxxxxxxxxx/ or the RFC: https://lore.kernel.org/netdev/20230117185714.3058453-6-netdev@xxxxxxxxxxxxxxxxxxxx/ and the change log does not mention it either. > I have at some point earlier asked why there would be two quite > equivalent flags and what the difference between them are, but I didn't > get a response. Actually, the part which you are now posing as a question (what is the difference?) was part of the premise of your earlier question (there is no difference => why do we have both?). https://lore.kernel.org/netdev/d972e76bed896b229d9df4da81ad8eb4@xxxxxxxxxxxxxxxxxxxx/ I believe that no one answered because the question was confused and it wasn't really clear what you were asking. > > Now I see the difference and that I cannot use the offloaded flag > without changing the behaviour of the system as I actually change the > behaviour of the offloaded flag in this version of the patch-set. > > So if the idea of a 'synthetically' learned fdb entry from the driver > using the SWITCHDEV_FDB_ADD_TO_BRIDGE event from the driver towards the > bridge instead is accepted, I can go with that? > (thus removing all the changes in the patch-set regarding the offloaded > flag ofcourse) which idea is that, again?
