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>.
