DPDK provides dpdk-pdump tool for capturing the packets to pcap file, which can be passed to tcpdump like tool to view the packets.
Please refer below DPDK documentation on the same. If you have further questions on the usage, please do send mail on to users@dpdk.org.
It does effect the performance so it is recommended to use it for debugging purposes.
