[PATCH v2 net-next 00/10] net: ocelot: VCAP IS1 and ES0 support

[Xiaoliang Yang]

This series patches adds support for VCAP IS1 and ES0 module, each VCAP
correspond to a flow chain to offload.

VCAP IS1 supports FLOW_ACTION_VLAN_MANGLE action to filter MAC, IP,
VLAN, protocol, and TCP/UDP ports keys and retag vlian tag,
FLOW_ACTION_PRIORITY action to classify packages to different Qos in hw.

VCAP ES0 supports FLOW_ACTION_VLAN_PUSH action to filter vlan keys
and push a specific vlan tag to frames.

Changes since v1->v2:
 - Use different chain to assign rules to different hardware VCAP, and
   use action goto chain to express flow order.
 - Add FLOW_ACTION_PRIORITY to add Qos classification on VCAP IS1.
 - Multiple actions support.
 - Fix some code issues.
