There is only one exception, which is only tested through iproute2 and defines multiple XDP programs within the same BPF object. Given iproute2 still works in non-strict libbpf mode and it doesn't have means to specify XDP programs by its name (not section name/title), leave that single file alone for now until iproute2 gains lookup by function/program name.
