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. Example of RTE_FLOW_ACTION_TYPE_MODIFY_FIELD implementation for MLX5: https://patchwork.dpdk.org/patch/86736/ Acked-by: Ajit Khaparde --- 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: https://patchwork.dpdk.org/cover/86705/ Redesigned as RTE_FLOW_ACTION_TYPE_MODIFY_FIELD. v6: https://patchwork.dpdk.org/cover/86715/ Fixed typos in documentation. v7: https://patchwork.dpdk.org/cover/86718/ Fixed warnings. v8: Added doxygen comments.
