Subject: [PATCH net-next 2/2] flow_offload: reject offload for all drivers with invalid police parameters
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. As hardware
can't configure peakrate/avrate/overhead, offload should not be
supported if any of them is configured.
