net: mscc: ocelot: Implement port policers via tc command
Hardware offload of matchall classifier and police action are now
supported via the tc command.
Supported police parameters are: rate and burst.
Example:
Add:
tc qdisc add dev eth3 handle ffff: ingress
tc filter add dev eth3 parent ffff: prio 1 handle 2 \
matchall skip_sw \
action police rate 100Mbit burst 10000
Show:
tc -s -d qdisc show dev eth3
tc -s -d filter show dev eth3 ingress
Delete:
tc filter del dev eth3 parent ffff: prio 1
tc qdisc del dev eth3 handle ffff: ingress
