We tried hard to use the hardware as a storage area, which made things needlessly complex in that we had to both marshall and unmarshall the ethtool_rx_flow_spec into what the CFP hardware understands but it did not require any driver level allocations, so that was nice. Keep a copy of the ethtool_rx_flow_spec rule we want to insert, and also make sure we don't have a duplicate rule already. This greatly speeds up the deletion time since we only need to clear the slice's valid bit and not perform a full read. This is a preparatory step for being able to restore rules upon system resumption where the hardware loses its context partially or entirely. Signed-off-by:
