Hi Team,

I am getting following error while running l2fwd application

[root@SERVER84 dpdk-21.08]# ./build/examples/dpdk-helloworld
EAL: Detected 40 lcore(s)
EAL: Detected 2 NUMA nodes
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'PA'
EAL: VFIO support initialized
TELEMETRY: No legacy callbacks, legacy socket not created
hello from core 0

After reading through the mailing list I got to know that -d option is used
pass the drivers path. Even after that I am getting the following error
message:
