DPDK version: 5f37ee9c859f3ce08ca4364f1d8c0e70ec33ac83 version: 25.03.0-rc2
OS: Ubuntu24.04.1 LTS (Noble Numbat)/6.8.0-41-generic
Compiler:  gcc version 13.2.0
Hardware platform: Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz
NIC hardware: CVL(Intel Corporation Ethernet Controller E810-C for SFP
[8086:1593])
NIC firmware:=20
  driver: vfio-pci
  kdriver: ice-1.16.3

Test Setup
Steps to reproduce
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
1. create 1 vf and set vf=20
echo 1 > /sys/bus/pci/devices/0000\:18\:00.0/sriov_numvfs
ip link set enp24s0f0np0 vf 0 trust on
ip link set enp24s0f0np0 vf 0 spoofchk off
modprobe vfio-pci
./usertools/dpdk-devbind.py -b vfio-pci 0000:18:01.0

2. start testpmd=20
x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-3 -n 4 -a 0000:18:01.0 -- =
-i
--enable-rx-cksum

3. set testpmd=20
set verbose 1
set promisc 0 on
set fwd csum
port stop all
csum set ip hw 0
csum set udp hw 0
csum set tcp hw 0
csum set sctp hw 0
csum set outer-ip hw 0
csum set outer-udp hw 0
csum parse-tunnel on 0
port start all
start

4. tcpdump captures packets forwarded by testpmd
tcpdump -ei ens8 -Q in -w 1.pcap

5. scapy send packets
from scapy.contrib.gtp import *
p=3DEther(dst=3D"76:D4:6B:F1:BF:7A", src=3D"52:00:00:00:00:0=
0") / IP(src =3D
"10.0.0.1", chksum =3D 0xff) / UDP(dport =3D 2182, chksum =3D 0xf=
f) /
GTP_U_Header(gtp_type=3D255, teid=3D0x123456) / IP(src =3D "10.0.0.1&q=
uot;, chksum =3D 0xff)
/ UDP(sport =3D 29999, dport =3D 30000, chksum =3D 0xff) / Raw("x"=
; * 100)=20
sendp(p, iface=3D'ens8', count=3D1)

6. ^C exit tcpdump and scapy or wireshark parsing data packets
scapy parsing data packets:
from scapy.contrib.gtp import *
pkt=3Drdpcap('1.pcap')
pkt[0].show2()

    app/testpmd: use packet type parsing API

    1. Use rte_net_get_ptype() to parse packets instead.
    2. Support TSO for packets with IPv6 extension header.
