Compiler: gcc version 11.4.0
Hardware platform: Intel(R) Xeon(R) Gold 6140M CPU @ 2.30GHz
NIC hardware: 
Intel Corporation Ethernet Controller E810-C for SFP [8086:1593] (rev 02)
NIC firmware: 
driver: ice-1.13.0_rc99_4_gb8ad35697

[Test Setup]
1. Blind pf to vfio-pci
./usertools/dpdk-devbind.py -b vfio-pci 0000:05:00.0 0000:08:00.0
2. Launch testpmd
x86_64-native-linuxapp-gcc/app/dpdk-testpmd  -l 1-2 -n 4 -a 0000:05:00.0 -a
0000:08:00.0  --file-prefix=dpdk_302219_20231116020458      -- -i
3. Set tunnel tso 
testpmd> set verbose 1
testpmd> port stop all
testpmd> csum set ip hw 1
testpmd> csum set udp hw 1
testpmd> csum set tcp hw 1
testpmd> csum set sctp hw 1
testpmd> csum set outer-ip hw 1
testpmd> csum set outer-udp hw 1
testpmd> csum parse-tunnel on 1
testpmd> tunnel_tso set 800 1
testpmd> rx_vxlan_port add 4789 0
testpmd> set fwd csum
testpmd> port start all
testpmd> set promisc all off
testpmd> start
4. Send vxlan packet
sendp([Ether(dst="40:a6:b7:7b:3f:00",src="52:00:00:00:00:00")/IP(src="192.168.1.1",dst="192.168.1.2")/UDP(sport=1021,dport=4789)/VXLAN()/Ether(dst="40:a6:b7:7b:3f:00",src="52:00:00:00:00:00")/IP(src="192.168.1.1",dst="192.168.1.2")/TCP(sport=1021,dport=1021)/("X"*801)],
iface="ens2f1")
5. show port status
testpmd> show port stats all 

[Show the output from the previous commands.]
Vxlan package not segmented.
