Original work by Shagun Agrawal Signed-off-by: Rahul Lakkireddy Acked-by: Xiaoyu Min Acked-by: Andrew Rybchenko --- v3: - Replaced uint32_t with rte_be32_t to reflect the byte order of the new IPv4 addresses to rewrite. v2: - Rebased to tip. - Removed adding actions to app/test-pmd/config.c, to sync with rte_flow_conv() changes. v1 changes since RFC v2: - Updated comments, help messages, and doc to indicate that IP/TCP/UDP of the outermost headers are modified. - Updated comments and doc to indicate that a corresponding valid flow pattern item must be specified to offload corresponding header rewrite action. - Updated release notes. app/test-pmd/cmdline_flow.c | 104 ++++++++++++++++++++ doc/guides/prog_guide/rte_flow.rst | 72 ++++++++++++++ doc/guides/rel_notes/release_18_11.rst | 7 ++ doc/guides/testpmd_app_ug/testpmd_funcs.rst | 18 ++++ lib/librte_ethdev/rte_flow.c | 8 ++ lib/librte_ethdev/rte_flow.h | 70 +++++++++++++ 6 files changed, 279 insertions(+) diff --git a/app/test-pmd/cmdline_flow.c b/app/test-pmd/cmdline_flow.c index f9260600e..1432498a3 100644 --- a/app/test-pmd/cmdline_flow.c +++ b/app/test-pmd/cmdline_flow.c @@ -243,6 +243,14 @@ enum index { ACTION_VXLAN_DECAP, ACTION_NVGRE_ENCAP, ACTION_NVGRE_DECAP, + ACTION_SET_IPV4_SRC, + ACTION_SET_IPV4_SRC_IPV4_SRC, + ACTION_SET_IPV4_DST, + ACTION_SET_IPV4_DST_IPV4_DST, + ACTION_SET_IPV6_SRC, + ACTION_SET_IPV6_SRC_IPV6_SRC, + ACTION_SET_IPV6_DST, + ACTION_SET_IPV6_DST_IPV6_DST, };
