A new ndo that does what? It would be exclusively called by sockets? We have packet traps with tc, packet traps with devlink, a mechanism for switchdev host MDBs, and from the discussion with you I also gather that there should be an equivalent switchdev object for host FDBs, that the bridge would use. So we would need yet another mechanism to extract packets from the hardware data path? I am simply lacking the clarity about what the new ndo you're talking about should do.
