Supported\nVxLAN packets must have an outer IPv4 header (prepended by an optional\nVLAN tag), and contain an inner TCP/IPv4 packet (with an optional inner\nVLAN tag).\n\nVxLAN GSO assumes that all input packets have correct checksums and\ndoesn't update checksums for output packets. Additionally, it doesn't\nprocess IP fragmented packets.\n\nAs with TCP/IPv4 GSO, VxLAN GSO uses a two-segment MBUF to organize each\noutput packet, which mandates support for multi-segment mbufs in the TX\nfunctions of the NIC driver. Also, if a packet is GSOed, VxLAN GSO\nreduces its MBUF refcnt by 1. As a result, when all of its GSOed\nsegments are freed, the packet is freed automatically.\n\nSigned-off-by: Mark Kavanagh <mark.b.kavanagh@intel.com>\nSigned-off-by: Jiayu Hu <jiayu.hu@intel.com>\n---\n lib/librte_gso/Makefile | 1 +\n lib/librte_gso/gso_common.c | 48 ++++++++++++++++++++++-\n lib/librte_gso/gso_common.h | 33 ++++++++++++++++\n lib/librte_gso/gso_tunnel_tcp4.c | 85 ++++++++++++++++++++++++++++++++++++++++\n lib/librte_gso/gso_tunnel_tcp4.h | 76 +++++++++++++++++++++++++++++++++++\n lib/librte_gso/rte_gso.c | 7 +++-\n 6 files changed, 248 insertions(+), 2 deletions(-)\n create mode 100644 lib/librte_gso/gso_tunnel_tcp4.c\n create mode 100644 lib/librte_gso/gso_tunnel_tcp4.h", "diff": "diff --git a/lib/librte_gso/Makefile b/lib/librte_gso/Makefile\nindex 2be64d1..e6d41df 100644\n--- a/lib/librte_gso/Makefile\n+++ b/lib/librte_gso/Makefile\n@@ -44,6 +44,7 @@ LIBABIVER := 1\n SRCS-$(CONFIG_RTE_LIBRTE_GSO) += rte_gso.c\n SRCS-$(CONFIG_RTE_LIBRTE_GSO) += gso_common.c\n SRCS-$(CONFIG_RTE_LIBRTE_GSO) += gso_tcp4.c\n+SRCS-$(CONFIG_RTE_LIBRTE_GSO) += gso_tunnel_tcp4.c\n \n # install this header file\n SYMLINK-$(CONFIG_RTE_LIBRTE_GSO)-include += rte_gso.h\ndiff --git a/lib/librte_gso/gso_common.c b/lib/librte_gso/gso_common.c\nindex 7c32e03..c6779d0 100644\n--- a/lib/librte_gso/gso_common.c\n+++ b/lib/librte_gso/gso_common.c\n@@ -39,6 +39,7 @@\n #include <rte_ether.h>\n #include <rte_ip.h>\n #include <rte_tcp.h>\n+#include <rte_udp.h>\n \n #include \"gso_common.h\"\n \n@@ -193,10 +194,55 @@ update_inner_tcp4_header(struct rte_mbuf *pkt, uint8_t ipid_delta,\n \t}\n }\n \n+static inline void\n+update_outer_ipv4_header(struct rte_mbuf *pkt, uint16_t id)\n+{\n+\tstruct ipv4_hdr *ipv4_hdr;\n+\n+\tipv4_hdr = (struct ipv4_hdr *)(rte_pktmbuf_mtod(pkt, char *) +\n+\t\t\tpkt->outer_l2_len);\n+\tipv4_hdr->total_length = rte_cpu_to_be_16(pkt->pkt_len -\n+\t\t\tpkt->outer_l2_len);\n+\tipv4_hdr->packet_id = rte_cpu_to_be_16(id);\n+}\n+\n+static inline void\n+update_outer_udp_header(struct rte_mbuf *pkt)\n+{\n+\tstruct udp_hdr *udp_hdr;\n+\tuint16_t length;\n+\n+\tlength = pkt->outer_l2_len + pkt->outer_l3_len;\n+\tudp_hdr = (struct udp_hdr *)(rte_pktmbuf_mtod(pkt, char *) +\n+\t\t\tlength);\n+\tudp_hdr->dgram_len = rte_cpu_to_be_16(pkt->pkt_len - length);\n+}\n+\n+static inline void\n+update_ipv4_vxlan_tcp4_header(struct rte_mbuf *pkt, uint8_t ipid_delta,\n+\t\tstruct rte_mbuf **segs, uint16_t nb_segs)\n+{\n+\tstruct ipv4_hdr *ipv4_hdr;\n+\tuint16_t i, id;\n+\n+\tipv4_hdr = (struct ipv4_hdr *)(rte_pktmbuf_mtod(pkt, char *) +\n+\t\t\tpkt->outer_l2_len);\n+\tid = rte_be_to_cpu_16(ipv4_hdr->packet_id);\n+\tfor (i = 0;
