A simple, very limited, implementation of a UDP echo server using DPDK (23.11).
Based on the Basic Forwarding Sample Application in the DPDK examples directory.
Follow the instruction in the Getting Started Guide for Linux

Bind a device to DPDK
$ sudo $RTE_SDK/usertools/dpdk-devbind.py --bind=vfio-pci 03:00.0
The output of the --status command should now look something like this
$ $RTE_SDK/usertools/dpdk-devbind.py --status
