As more police parameters are passed to flow_offload, driver can check them to make sure hardware handles packets in the way indicated by tc. The conform-exceed control should be drop/pipe or drop/ok. Besides, for drop/ok, the police should be the last action. As hardware can't configure peakrate/avrate/overhead, offload should not be supported if any of them is configured.
