This patch adds support for offloading port objects, VLANs and MDBs, added on upper bond devices. First of all, the use of the switchdev_handle_*() replication helpers is introduced for the SWITCHDEV_PORT_OBJ_ADD/SWITCHDEV_PORT_OBJ_DEL events. With this change, setting up the 'port_obj_info->handled = true' is not needed anymore since it's now handled by the new helpers. In the DPAA2 architecture, there is no difference in adding a FDB or MDB which points towards a LAG port. Unlike other architectures, we do not need to populate all the possible destinations which are under the LAG, we only have to specify a single queueing destination (QDID) which represents the LAG. This all means that handling of MDBs in bond devices needs to have refcount mechanism as with the FDBs. This mechanism is triggered by calling the dpaa2_switch_lag_fdb_add() / dpaa2_switch_lag_fdb_del() functions which were added in the previous patch. Also change how dpaa2_switch_port_mdb_del() behaves in case the underlying HW operation failed. Since the delete operations cannot be stopped from a switchdev standpoint, go ahead and ignore the return code from the dpaa2_switch_*_fdb_del() calls.
