   Data	Fields
       enum rte_flow_field_id field
       uint8_t level
       uint8_t tag_index
       uint8_t type

Detailed Description
       Warning
	   EXPERIMENTAL: this structure	may change without prior notice.

       Packet header field descriptions, used by
       RTE_FLOW_ACTION_TYPE_MODIFY_FIELD and RTE_FLOW_ITEM_TYPE_COMPARE.

       Definition at line 2449 of file rte_flow.h.

Field Documentation
   enum	rte_flow_field_id field
       Field or	memory type ID.

       Definition at line 2450 of file rte_flow.h.

   uint8_t level
       Packet encapsulation level containing the field to modify.

       • 0 requests the	default	behavior. Depending on the packet type,	it can
	 mean outermost, innermost or anything in between.

       It basically stands for the innermost encapsulation level. Modification
       can be performed	according to PMD and device capabilities.

       • 1  requests  modification  to	be  performed  on the outermost	packet
	 encapsulation level.

       • 2 and subsequent values request modification to be performed  on  the
	 specified   inner  packet  encapsulation  level,  from	 outermost  to
	 innermost (lower to higher values).

       Values other than 0 are not necessarily supported.

       Note
	   that	for MPLS field,	encapsulation level also include tunnel	 since
	   MPLS	may appear in outer, inner or tunnel.

       Definition at line 2490 of file rte_flow.h.

   uint8_t tag_index
       Tag  index array	inside encapsulation level. Used for VLAN, MPLS	or TAG
       types.

       Definition at line 2497 of file rte_flow.h.

   uint8_t type
       Geneve option type.

       Definition at line 2508 of file rte_flow.h.

   rte_be16_t class_id
       Geneve option class.

       Definition at line 2512 of file rte_flow.h.

   uint32_t offset
       Number of bits to skip from a field.

       Definition at line 2519 of file rte_flow.h.

   uint8_t value[16]
       Immediate value for RTE_FLOW_FIELD_VALUE, presented in  the  same  byte
       order and length	as in relevant rte_flow_item_xxx. The immediate	source
       bitfield	offset is inherited from the destination's one.

       Definition at line 2527 of file rte_flow.h.

   void* pvalue
       Memory  address for RTE_FLOW_FIELD_POINTER, memory layout should	be the
       same as for relevant field in the rte_flow_item_xxx structure.

       Definition at line 2533 of file rte_flow.h.
