Can I use DPDK as a packet capture module for a network monitoring application?

My passive network monitoring application needs packets to be captured from network interface (at higher packet rates). The packet capture module should be able to call a monitoring function upon capture of each packet (and also write the packet in to pcap file).

I thought of using DPDK as the packet capture module in my monitoring application (as we use pcap_loop and pfring_loop in libpcap and pfring respectively), but I am not sure whether this is one of the use cases of DPDK, or, is DPDK meant to be used like this?.

So my questions are.. Can I use DPDK to fulfill my requirements?, If yes how to start?.

OS: Linux.
Karnal version: 4.
DPDK version: Latest stable.
Capture on physical device.
The capturing application has root privileges and will be used by the network administrator (as part of passive asset discovery).
I want to use DPDK because it supports capture at line rate upto 10 Gbps

Thank you.
