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

1, Build app
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Denable_kmods=True -Dlibdir=lib  --default-library=static
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc -j 100  meson configure -Dexamples=dma
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
ls x86_64-native-linuxapp-gcc/examples/dpdk-dma

2, Bind nic and dma to vfio-pci
./usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:4b:00.0 0000:00:01.0

3, Launch app
x86_64-native-linuxapp-gcc/examples/dpdk-dma  -l 5-6 -n 8 -a 0000:4b:00.0 -a
0000:00:01.0  --file-prefix=cbdma_690149_20240219131328     
--proc-type=primary  -- -p 0x1 -q 1 --mac-updating -c hw

Show the output from the previous commands:
 x86_64-native-linuxapp-gcc/examples/dpdk-dma  -l 5-6 -n 8 -a 0000:4b:00.0 -a
0000:00:01.0  --file-prefix=cbdma_690149_20240219131328     
--proc-type=primary  -- -p 0x1 -q 1 --mac-updating -c hw
