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 | 109 ++++++++++++++++++++++++++++++++++++++++++--\n lib/librte_gso/gso_common.h | 41 ++++++++++++++++-\n lib/librte_gso/gso_tunnel.c | 62 +++++++++++++++++++++++++\n lib/librte_gso/gso_tunnel.h | 46 +++++++++++++++++++\n lib/librte_gso/rte_gso.c | 12 ++++-\n lib/librte_gso/rte_gso.h | 4 ++\n 7 files changed, 268 insertions(+), 7 deletions(-)\n create mode 100644 lib/librte_gso/gso_tunnel.c\n create mode 100644 lib/librte_gso/gso_tunnel.h", "diff": "diff --git a/lib/librte_gso/Makefile b/lib/librte_gso/Makefile\nindex 0f8e38f..a4d1a81 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-$(CONFIG_RTE_LIBRTE_GSO) += gso_tcp.c\n+SRCS-$(CONFIG_RTE_LIBRTE_GSO) += gso_tunnel.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 2b54fbd..65cec44 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@@ -156,18 +157,60 @@ gso_do_segment(struct rte_mbuf *pkt,\n \treturn nb_segs;\n }\n \n+static inline void parse_ethernet(struct ether_hdr *eth_hdr,\n+\t\tstruct rte_mbuf *pkt);\n+\n+static inline void\n+parse_vxlan(struct udp_hdr *udp_hdr, struct rte_mbuf *pkt)\n+{\n+\tstruct ether_hdr *eth_hdr;\n+\n+\teth_hdr = (struct ether_hdr *)((char *)udp_hdr +\n+\t\t\tsizeof(struct udp_hdr) +\n+\t\t\tsizeof(struct vxlan_hdr));\n+\n+\tpkt->packet_type |= RTE_PTYPE_TUNNEL_VXLAN;\n+\tpkt->outer_l2_len = pkt->l2_len;\n+\tparse_ethernet(eth_hdr, pkt);\n+\tpkt->l2_len += ETHER_VXLAN_HLEN;
