Function works. And after comparing the pe= rf with cases without vxlan tso, the perf is similar. Can't see obvious drop. Tested with both 19.11 & newest commit b8d81e9cbf5e. Both work fine. So it's not a bug of i40e driver. Test steps: ixia generates packets with len 1500, and udp dst port 4789 (vxlan), and ou= ter udp payload with vxlan and inner tcp packets. ixia rx port to observe the bytes receive rate. Both cases can get about 3G= Bps perf (using XXV710). If using vxlan tso: ./build/app/dpdk-testpmd -l 28,29,30,31 -n 4 -w 86:00.0 -w 86:00.1 =E2=80= =93 -i port stop all csum set ip hw 0 csum set udp hw 0 csum set tcp hw 0 csum set outer-ip hw 0 csum set outer-udp hw 0 csum set sctp hw 0 csum parse-tunnel on 0 csum set ip hw 1 csum set udp hw 1 csum set tcp hw 1 csum set outer-ip hw 1 csum set outer-udp hw 1 csum set sctp hw 1 csum parse-tunnel on 1 tunnel_tso set 800 1 rx_vxlan_port add 4789 0 set fwd csum port start all start If without vxlan tso: ./build/app/dpdk-testpmd -l 28,29,30,31 -n 4 -w 86:00.0 -w 86:00.1 =E2=80= =93 -i rx_vxlan_port add 4789 0 start --=20 You are receiving this mail because: You are the assignee for the bug.=
