Compiler: gcc version 11.4.0
Hardware platform: Intel(R) Xeon(R) Platinum 8280M CPU @ 2.70GHz

[Test Setup]
Steps to reproduce
List the steps to reproduce the issue.

1.Build dpdk
rm -rf x86_64-native-linuxapp-gcc
CC=3Dgcc meson -Denable_kmods=3DTrue -Dlibdir=3Dlib  --default-library=3Dst=
atic

2.Launch vhost as client mode

--nb-cores=3D2 --rxq=3D2 --txq=3D2

3, Launch virtio-user as server mode
x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 4-6 -n 4  --file-prefix=3Dvi=
rtio1
--no-pci --vdev
'net_virtio_user0,mac=3D00:01:02:03:04:05,path=3D./vhost-net,server=3D1,que=
