-/* LLVM's BPF target selects the endianness of the CPU

- * the compiler, we cannot rely on __BYTE_ORDER from
- * libc headers, since it doesn't reflect the actual
- * requested byte order.
- *
- * Note, LLVM's BPF target has different __builtin_bswapX()
- * semantics. It does map to BPF_ALU | BPF_END | BPF_TO_BE
- * in bpfel and bpfeb case, which means below, that we map
- * to cpu_to_be16(). We could use it unconditionally in BPF
- * case, but better not rely on it, so that this header here
- * can be used from application and BPF program side, which
- * use different targets.
