dpdk fuzz test file

Environment
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
DPDK version: 5f37ee9c859f3ce08ca4364f1d8c0e70ec33ac83 version: 25.03.0-rc2
OS: Red Hat Enterprise Linux 9.4/5.14.0-427.13.1.el9_4.x86_64
Compiler: clang version 17.0.6
Hardware platform: Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz
NIC hardware: N/A
NIC firmware: N/A

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 packet file(If the environment already has these packets, can skip
this step)
mkdir -p /tmp/fuzz/vhost_pcap
python3 pkt.py

2. Compile dpdk and fuzz
tar zxf fuzz.tar.gz
cp -r fuzz /root/dpdk/app/=20
sed -i "s/'test-sad',/'test-sad',\n        'fuzz',/g" app/meson.b=
uild

rm -rf x86_64-native-linuxapp-clang
CC=3Dclang meson --werror -Denable_kmods=3DTrue -Dbuildtype=3Ddebug -Db_lun=
def=3Dfalse
-Db_sanitize=3Daddress x86_64-native-linuxapp-clang
ninja -C x86_64-native-linuxapp-clang

3. create vhost
rm -rf /tmp/sock0
x86_64-native-linuxapp-clang/app/dpdk-fuzz /tmp/fuzz/vhost_pcap/ --
-ignore_remaining_args=3D1 -l 1 -n 4  --file-prefix=3Dvhost --vdev
'net_vhost0,iface=3D/tmp/sock0,queues=3D4' -- --rxq=3D4 --txq=3D4 --txd=3D1=
024 --rxd=3D1024=20
RTE>>vhost_autotest

4. start testpmd with virtio device=20
x86_64-native-linuxapp-clang/app/dpdk-testpmd -l 1,2 -n 4
--file-prefix=3Dvirtio_26049_20250311133724 --no-pci
--vdev=3Dnet_virtio_user0,mac=3D00:01:02:03:04:05,path=3D/tmp/sock0,queues=
=3D4 -- -i
--rxq=3D4 --txq=3D4 --txd=3D1024 --rxd=3D1024

5. set csum fwd and start fwd
set fwd csum
start
show port stats all
note: Loop query the port status. when the bps of the port receiving and
transmitting packets is found to be 0, exit testpmd.

6. exit testpmd
quit

Results:=20
=3D=3D=3D=3D=3D=3D=3D=3D
Unable to exit testpmd, will get stuck.

Expected Result:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Testpmd receives and sends packets normally and exits normally.

    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.
