Hi team,

I recently installed dpdk on linux and i am doing the experiments on
examples.
after executing the basic forwarding example i am getting below error.
Please help me to resolve this issue.
======================================
I used the commands below before executing the example binary.
mkdir -p /dev/hugepages
mountpoint -q /dev/hugepages || mount -t hugetlbfs nodev /dev/hugepages
echo 1024 >
/sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
dpdk-devbind.py -s
ifconfig enp2s0 down
modprobe uio
modprobe uio_pci_generic
dpdk-devbind.py -s
dpdk-devbind.py -b uio_pci_generic 02:00.0
dpdk-devbind.py -s
cd /home/rsys/dpdk-23.07/build/examples
============================================
============================================
After this status will be
root@rsys:/home/rsys/dpdk-23.07/build/examples# dpdk-devbind.py -s

==============================================
The error will be
