selftests/bpf: Fix a selftest compilation error When building the kernel and selftest with clang compiler (llvm17 or llvm18), I hit the following compilation failure: In file included from progs/test_lwt_redirect.c:3: In file included from /usr/include/linux/ip.h:21: In file included from /usr/include/asm/byteorder.h:5: In file included from /usr/include/linux/byteorder/little_endian.h:13: /usr/include/linux/swab.h:136:8: error: unknown type name '__always_inline' 136 | static __always_inline unsigned long __swab(const unsigned long y) | ^ /usr/include/linux/swab.h:171:8: error: unknown type name '__always_inline' 171 | static __always_inline __u16 __swab16p(const __u16 *p) ... bpf_helpers.h file provided a definition for __always_inline. Putting 'ip.h' after 'bpf_helpers.h' fixed the issue.

selftests/bpf: Add lwt_xmit tests for BPF_REDIRECT There is no lwt_xmit test case for BPF_REDIRECT yet. Add test cases for both normal and abnormal situations. For abnormal test cases, devices are set down or have its carrier set down. Without proper fixes, BPF_REDIRECT to either ingress or egress of such device would panic the kernel.
