selftests: add dummy xdp test helper This trivial XDP program does nothing, but will be used by the next patch to test the GRO path in a net namespace, leveraging the veth XDP implementation. It's added here, despite its 'net' usage, to avoid the duplication of the llc-related makefile boilerplate. rfc v3 -> v1: - move the helper implementation into the bpf directory, don't touch udpgso_bench_rx rfc v2 -> rfc v3: - move 'x' option handling here Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.

selftests: Use consistent include paths for libbpf Fix all selftests to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted. To not break the build, keep the old include path until everything has been changed to the new one; a subsequent patch will remove that.
