Subject: [PATCH v7 net-next 0/8] net: dsa: felix: psfp support on vsc9959

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.

v6-v7 changes:
 - Add a patch to restrict psfp rules on ingress port.
 - Using stats.drops to show the packet count discarded by the rule.

v5->v6 changes:
 - Modify ocelot_mact_lookup() parameters.
 - Use parameters ssid and sfid instead of streamdata in
   ocelot_mact_learn_streamdata() function.
 - Serialize STREAMDATA and MAC table write.

v4->v5 changes:
 - Add MAC table lock patch, and move stream data write in
   ocelot_mact_learn_streamdata().
 - Add two sections of VCAP policers to Seville platform.

v3->v4 changes:
 - Introduce vsc9959_psfp_sfi_table_get() function in patch where it is
   used to fix compile warning.

v2->v3 changes:
 - Reorder first two patches. Export struct ocelot_mact_entry, then add
   ocelot_mact_lookup() and ocelot_mact_write() functions.
 - Add PSFP list to struct ocelot, and init it by using
   ocelot->ops->psfp_init().

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.
