octeontx2-pf: Add police action for TC flower
Added police action for ingress TC flower
hardware offload. With this rate limiting can be
done per flow. Since rate limiting is tied to
RQs in hardware the number of TC flower filters
with action as police is limited to number
of receive queues of the interface. Both bps
and pps modes are supported.
Examples to rate limit a flow:
$ ethtool -K eth0 hw-tc-offload on
$ tc qdisc add dev eth0 ingress
$ tc filter add dev eth0 parent ffff: protocol ip \
flower ip_proto udp dst_port 80 action \
police rate 100Mbit burst 32Kbit
$ tc filter add dev eth0 parent ffff: \
protocol ip flower dst_mac 5e:b2:34:ee:29:49 \
action police pkts_rate 5000 pkts_burst 2048
