[dpdk-dev] [PATCH 1/8] librte_ethdev: add new flow types and action

[Bernard Iremonger <bernard.iremonger@intel.com>]

In rte_flow.h:
add RTE_FLOW_ITEM_TYPE_PCTYPE
add RTE_FLOW_ITEM_TYPE_FLOWTYPE
add RTE_FLOW_ACTION_TYPE_MAP
add structs and masks for new flow types

In rte_flow.rst:
add items for pctype and flowtype
add action for map
