The code uses a\nunion to ensure that existing code continues to work as before, while\nallowing the improved more usable method to co-exist.\n\nA new #define is introduced to represent the instance bit, which must be\nset if a vxlan header contains a valid VNI field, see\nhttps://datatracker.ietf.org/doc/html/rfc7348 for details\n\nSigned-off-by: Ronan Randles <ronan.randles@intel.com>\n---\n lib/net/rte_vxlan.h | 10 +++++++++-\n 1 file changed, 9 insertions(+), 1 deletion(-)", "diff": "diff --git a/lib/net/rte_vxlan.h b/lib/net/rte_vxlan.h\nindex 929fa7a1dd..86b6d8a3ae 100644\n--- a/lib/net/rte_vxlan.h\n+++ b/lib/net/rte_vxlan.h\n@@ -24,6 +24,7 @@ extern \"C\" {\n /** VXLAN default port. */\n #define RTE_VXLAN_DEFAULT_PORT 4789\n #define RTE_VXLAN_GPE_DEFAULT_PORT 4790\n+#define RTE_VXLAN_FLAGS_I (1 << 3)\n \n /**\n * VXLAN protocol header.\n@@ -31,7 +32,14 @@ extern \"C\" {\n * Reserved fields (24 bits and 8 bits)\n */\n struct rte_vxlan_hdr {\n-\trte_be32_t vx_flags; /**< flag (8) + Reserved (24). */\n+\tRTE_STD_C11\n+\tunion {\n+\t\tstruct {\n+\t\t\tuint8_t vx_flag_bits;\n+\t\t\tuint8_t reserved[3];\n+\t\t};\n+\t\trte_be32_t vx_flags; /**< flag (8) + Reserved (24). */\n+\t};\n \trte_be32_t vx_vni; /**< VNI (24) + Reserved (8). */\n } __rte_packed;\n \n", "prefixes": [ "v2", "14/15" ] }
