Implement a generic modify rte flow API as described in RFC: http://patches.dpdk.org/patch/85384/
This API allows modifying a destination header field with data from a source header field. Number of bits to use from the 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. v6: Fixed typos in documentation.
