In some IPv4-only clients, it is hard to deploy\nnew software and hardware to support IPv6.\n\nNAT64 is a choice and it will also reduce the unnecessary overhead of\nthe traffic in the network. The NAT64 gateways take the\nresponsibility of the packet headers translation between the IPv6\nclouds and IPv4-only clouds.\n\nThis action should support the offloading of the IP headers'\ntranslation. The following fields should be reset correctly in the\ntranslation.\n - Version\n - Traffic Class / TOS\n - Flow Label (0 in v4)\n - Payload Length / Total length\n - Next Header\n - Hop Limit / TTL\n\nSince there are different mapping and translating modes of the\naddresses, it will depend on the capabilities of each vendor.\n\nThe ICMP* and transport layers protocol is out of the scope of NAT64\nrte_flow action.\n\nReference links:\n - https://datatracker.ietf.org/doc/html/rfc6146\n - https://datatracker.ietf.org/doc/html/rfc6052\n - https://datatracker.ietf.org/doc/html/rfc6145\n\nSigned-off-by: Bing Zhao <bingz@nvidia.com>\n---\n lib/ethdev/rte_flow.c | 1 +\n lib/ethdev/rte_flow.h | 27 +++++++++++++++++++++++++++\n 2 files changed, 28 insertions(+)", "diff": "diff --git a/lib/ethdev/rte_flow.c b/lib/ethdev/rte_flow.c\nindex 271d854f78..b60a4f6654 100644\n--- a/lib/ethdev/rte_flow.c\n+++ b/lib/ethdev/rte_flow.c\n@@ -265,6 +265,7 @@ static const struct rte_flow_desc_data rte_flow_desc_action[] = {\n \tMK_FLOW_ACTION(IPV6_EXT_REMOVE, sizeof(struct rte_flow_action_ipv6_ext_remove)),\n \tMK_FLOW_ACTION(INDIRECT_LIST,\n \t\t sizeof(struct rte_flow_action_indirect_list)),\n+\tMK_FLOW_ACTION(NAT64, sizeof(struct rte_flow_action_nat64)),\n };\n \n int\ndiff --git a/lib/ethdev/rte_flow.h b/lib/ethdev/rte_flow.h\nindex 86ed98c562..2002999a35 100644\n--- a/lib/ethdev/rte_flow.h\n+++ b/lib/ethdev/rte_flow.h\n@@ -2989,6 +2989,13 @@ enum rte_flow_action_type {\n \t * @see struct rte_flow_action_indirect_list\n \t */\n \tRTE_FLOW_ACTION_TYPE_INDIRECT_LIST,\n+\n+\t/**\n+\t * Support the NAT64 translation.\n+\t *\n+\t * @see struct rte_flow_action_nat64\n+\t */\n+\tRTE_FLOW_ACTION_TYPE_NAT64,\n };\n \n /**\n@@ -4092,6 +4099,26 @@ rte_flow_dynf_metadata_set(struct rte_mbuf *m, uint32_t v)\n \t*RTE_FLOW_DYNF_METADATA(m) = v;\n }\n \n+/**\n+ * NAT64 translation type for IP headers.\n+ */\n+enum rte_flow_nat64_type {\n+\tRTE_FLOW_NAT64_6TO4 = 0, /**< IPv6 to IPv4 headers translation. */\n+\tRTE_FLOW_NAT64_4TO6 = 1, /**< IPv4 to IPv6 headers translation. */\n+};\n+\n+/**\n+ * @warning\n+ * @b EXPERIMENTAL: this structure may change without prior notice\n+ *\n+ * RTE_FLOW_ACTION_TYPE_NAT64\n+ *\n+ * Specify the NAT64 translation type.\n+ */\n+struct rte_flow_action_nat64 {\n+\tenum rte_flow_nat64_type type;\n+};\n+\n /**\n * Definition of a single action.\n *\n", "prefixes": [ "RFC" ] }
