For binary compatibility it isn't sufficient to just add new fields to struct dvbs2_params. There must also be an indicator which the kernel can use to see if struct dvb_frontend_params was prepared by old or new userspace, i.e. if the new fields are valid or contain uninitialized data. That's why I propsed a "flags" field for struct dvbs2_params in my version of the patch.
