nfp: flower: add support for packet-per-second policing

Browse source

Allow hardware offload of a policer action attached to a matchall filter
which enforces a packets-per-second rate-limit.

e.g.
tc filter add dev tap1 parent ffff: u32 match \
        u32 0 0 police pkts_rate 3000 pkts_burst 1000
