Number of bits to use from source is specified. Tag, mark or metadata can also be used as a source/destination to allow saving/overwriting an arbitrary header field with a user-specified value. Alternatively, an immediate value can be provided by a user as a source. Outermost/innermost packet fields (and Tag array elements) are accessible via the level parameter to facilitate the modification of encapsulated packet header fields. The offset parameter provides the flexibility to copy/set any part of a packet starting the specified packet header field. --- v1: https://patchwork.dpdk.org/patch/86173/ Initial design. v2: https://patchwork.dpdk.org/cover/86369/ Added testpmd support. v3: https://patchwork.dpdk.org/cover/86442/ Made dst_type, src_type and width only mandatory parameters. v4: https://patchwork.dpdk.org/cover/86488/ Renamed action to RTE_FLOW_ACTION_TYPE_COPY_FIELD. v5: Redesigned as RTE_FLOW_ACTION_TYPE_MODIFY_FIELD.
