Subject: [dpdk-dev] [PATCH v2 2/2] app/testpmd: add support for generic copy rte flow action
Date: Tue, 12 Jan 2021 05:01:10 +0000
Message-ID: <20210112050110.1987-3-akozyrev@nvidia.com> (raw)
In-Reply-To: <20210112050110.1987-1-akozyrev@nvidia.com>

Add support for the RTE_FLOW_ACTION_COPY_ITEM to the testpmd.
Implement CLI to create the copy_item action and supply all the
needed parameters to copy an arbitrary packet field (as well as
mark, tag or metadata) into another item.

Example of the flow is the following:
flow create 0 egress group 1 pattern eth / ipv4 / udp / end
     actions copy_item dst_type tag dst_index 0 dst_offset 8
     src_type gtp_teid src_index 0 src_offset 0 width 32 / end

This flow copies 32 bits from the first Tag in the Tags array
into the outermost GTP TEID packet header field. 8 bits of the Tag
are skipped as indicated by the dst_offset action parameter.
