  Subject: [PATCH] Avoid in6_addr redefinition
  MIME-Version: 1.0
  Content-Type: text/plain; charset=UTF-8
  Content-Transfer-Encoding: 8bit
  
  Due to both <netinet/in.h> and <linux/in6.h> being included, the
  in6_addr is being redefined: once from the C library headers and once
  from the kernel headers. This causes some build failures with for
  example the musl C library:
  
  In file included from ../include/linux/xfrm.h:4:0,
                   from xfrm.h:29,
                   from ipxfrm.c:39:
  ../include/linux/in6.h:32:8: error: redefinition of ‘struct in6_addr’
   struct in6_addr {
          ^
  In file included from .../output/host/usr/x86_64-buildroot-linux-musl/sysroot/usr/include/netdb.h:9:0,
                   from ipxfrm.c:34:
  .../output/host/usr/x86_64-buildroot-linux-musl/sysroot/usr/include/netinet/in.h:24:8: note: originally defined here
   struct in6_addr
          ^
  
  In order to fix this, use just the C library header <netinet/in.h>.
