selftests/bpf: fix compile errors due to unsync linux/in6.h and netinet/in.h
I meet below compile errors: " In file included from test_tcpnotify_kern.c:12: /usr/include/netinet/in.h:101:5: error: expected identifier IPPROTO_HOPOPTS = 0, /* IPv6 Hop-by-Hop options. */ ^ /usr/include/linux/in6.h:131:26: note: expanded from macro 'IPPROTO_HOPOPTS' ^ In file included from test_tcpnotify_kern.c:12: /usr/include/netinet/in.h:103:5: error: expected identifier IPPROTO_ROUTING = 43, /* IPv6 routing header. */ ^ /usr/include/linux/in6.h:132:26: note: expanded from macro 'IPPROTO_ROUTING' ^ In file included from test_tcpnotify_kern.c:12: /usr/include/netinet/in.h:105:5: error: expected identifier IPPROTO_FRAGMENT = 44, /* IPv6 fragmentation header. */ ^ /usr/include/linux/in6.h:133:26: note: expanded from macro 'IPPROTO_FRAGMENT' " The same compile errors are reported for test_tcpbpf_kern.c too. My environment: lsb_release -a: No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.6 LTS Release: 16.04 Codename: xenial dpkg -l | grep libc-dev: ii libc-dev-bin 2.23-0ubuntu11 amd64 GNU C Library: Development binaries ii linux-libc-dev:amd64 4.4.0-145.171 amd64 Linux Kernel Headers for development. The reason is linux/in6.h and netinet/in.h aren't synchronous about how to handle the same definitions, IPPROTO_HOPOPTS, etc. This patch fixes the compile errors by moving <netinet/in.h> to before the <linux/*.h>.
