When you use DPDK, the application gets raw control over the hardware.
The kernel device (used by tcpdump) is gone. Since it is a pure application
with responsibility for everything, you could write a capture application
that writes a pcap format file. Part of the downside of something like DPDK
is that sharing device with system is hard.
