What is it?

Generate UDP traffic using BPF_PROG_TEST_RUN and XDP. It is a simple replications of xdp-trafficgen [1]. The idea was to get familiar with the technique and also a simpler version that is easier to adjust for different possible needs.

Running

The source/destination address are hard-coded in runner.c::main()

make
sudo ./build/runner -i <iface>

Requirements

It requires a new kernel. It did not worked on v5.15. I tested with 6.7.3 and libbpf v1.0.0.
