What should a driver do if the user specifies DISABLED, but the stats
are still needed for internal bookkeeping (e.g. to prod an ARP entry
that's in use for encapsulation offload, so that it doesn't get
expired out of the cache)?  Enable the stats on the HW anyway but
not report them to FLOW_CLS_STATS?  Or return an error?
