Hello everyone, this small series is a first step in a larger effort aiming to help improve eBPF selftests and the testing coverage in CI. It focuses for now on test_xdp_veth.sh, a small test which is not integrated yet in test_progs. The series is mostly about a rewrite of test_xdp_veth.sh to make it able to run under test_progs, relying on libbpf to manipulate bpf programs involved in the test.
