Field description for MODIFY_FIELD action.

Field Documentation

enum rte_flow_field_id field

Field or memory type ID.

Definition at line 3856 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 3956 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 3963 of file rte_flow.h.

uint8_t type

Geneve option type.

Definition at line 3974 of file rte_flow.h.

rte_be16_t class_id

Geneve option class.

Definition at line 3978 of file rte_flow.h.

uint32_t offset

Number of bits to skip from a field.

Definition at line 3985 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 3993 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 3999 of file rte_flow.h.
