Mh ok, I hoped we could first have the base DSA driver merged before starting to applying these kind of feature. Concept looks handy, ideally I can just assign one ID for each port like: port 1 -> FIB 1 port 2 -> FIB 1 port 3 -> FIB 2 Question: Ports of the same bridge should have the same FIB? What I need to check is how the switch handle this for learning. Does the switch correctly create FDB entry with the right FIB? If that's not the case then I think assisted_learning is needed and HW Learn can't be used? (I still need to check if I can assign a default FIB for a port... Currently the STP register are 2 bit for each FIB id, so 16 different FIB are possible) Also do we have a script for selft tests? I remember there was one back in the days for fdb isolation? -- Ansuel
