Sounds interesting, please share :-)
iptables has the same issue, and solved it its way.
(uapi/)linux/netfilter.h is used to get at things like union
nf_inet_addr. This union contains struct in6_addr. There is no include
for in6_addr in netfilter.h itself. This may break the "standalone
compilation" test, but at least allows for specifying the
environment-specific header for in6_addr in the C file:
a. userspace: #include <netinet/in.h> before <linux/netfilter.h>
b. kernel parts: #include <linux/in6.h> before <linux/netfilter.h>
