Many NICs can't support\nVXLAN UDP UFO/USO and VLAN UFO/USO, so UDP performance\nimprovement depends on GSO and GRO to a great extent.\n\nThis patch series added VLAN UDP GRO and VXLAN UDP GRO\nsupport.\n\nI have tested it in OVS DPDK, test scenario is as below:\n\n+-------------------------+ +--------------------------+\n|VM1 --- OVS DPDK --- NIC1|---| NIC2 --- OVS-DPDK --- VM2|\n+-------------------------+ +--------------------------+\n SERVER1 SERVER2\n\nIf no GSO and GRO, 8k UDP packet can't work in case of UFO or\nin case that underlay MTU is 1500, so UDP size must meet MTU\nlimitation, my VM MTU is 1450 (consider vxlan header), UDP\nperformance is about 3Gbps, with GSO and GRO enabled, I can\nsend 8K UDP packet, UDP performance is about 6Gbps (Note: with\nsmall UDP packet loss rate). \n\nFYI: OVS DPDK patch series\nhttps://patchwork.ozlabs.org/project/openvswitch/list/?series=194621\n\nChangelog\n---------\nv3 -> v4: split two patches in cleaner way\n remove ip_id which is unnecessary for UDP GRO\n correct hdr_len calculation\n\nv2 -> v3: remove UDP header length check\n\nv1 -> v2: split into two patches\n\nYi Yang (2):\n gro: add UDP GRO support\n gro: add VXLAN UDP GRO support\n\n lib/librte_gro/Makefile | 2 +\n lib/librte_gro/gro_udp4.c | 430 +++++++++++++++++++++++++++++++\n lib/librte_gro/gro_udp4.h | 282 +++++++++++++++++++++\n lib/librte_gro/gro_vxlan_udp4.c | 548 ++++++++++++++++++++++++++++++++++++++++\n lib/librte_gro/gro_vxlan_udp4.h | 152 +++++++++++\n lib/librte_gro/meson.build | 2 +-\n lib/librte_gro/rte_gro.c | 192 +++++++++++---\n lib/librte_gro/rte_gro.h | 8 +-\n 8 files changed, 1582 insertions(+), 34 deletions(-)\n create mode 100644 lib/librte_gro/gro_udp4.c\n create mode 100644 lib/librte_gro/gro_udp4.h\n create mode 100644 lib/librte_gro/gro_vxlan_udp4.c\n create mode 100644 lib/librte_gro/gro_vxlan_udp4.h" }
