Testing applications using openNIC driver

[Nafiah8088]

I'm testing pktgen and testpmd application using openNIC driver in U200, where I'm facing issues the below issues
"testpmd 20.11 application"
sudo ./build/app/dpdk-testpmd -l 1-8 -n 4 --vdev="net_pcap0,iface=enp1s0f0" --vdev="net_pcap1,iface=enp1s0f1" -- -i
in transmission and reception of pkts, pkts are initially sent and received but evenutally come to a hault, this is while running the application.
"pktgen 23.06.1 application"
sudo ./usr/local/bin/pktgen -l 1-8 -n 4 --vdev="net_af_packet0,iface=enp1s0f0" --vdev="net_af_packet1,iface=enp1s0f1" -d librte_net_af_packet.so -- -m [5:6].0 -m [7:8].1
the same follows where I'm not able to send or receive packets
so I tried out few basic tests
ping works fine but no packets are captured using tcpdump
likewise used scapy as traffic generator and tcpdump for capturing it, the results were same
my OS details
cat /etc/os-release
