VSC9959 hardware supports Per-Stream Filtering and Policing(PSFP).
This patch series add PSFP support on tc flower offload of ocelot
driver. Use chain 30000 to distinguish PSFP from VCAP blocks. Add gate
and police set to support PSFP in VSC9959 driver.
v1->v2 changes:
- Use tc flower offload of ocelot driver to support PSFP add and delete.
- Add PSFP tables add/del functions in felix_vsc9959.c.
- Use list_for_each_entry to simplify the code.
- Fix PSFP tables add/del issue.

2.17.1
This patch add police action to set flow meter table which is defined
in IEEE802.1Qci. Flow metering is two rates two buckets and three color
marker to policing the frames, we only enable one rate one bucket in
this patch.
Flow metering shares a same policer pool with VCAP policers, so the PSFP
policer calls ocelot_vcap_policer_add() and ocelot_vcap_policer_del() to
set flow meter police.
