I played around with this code some more, but am still getting confused with nlmsg_new and NLMSG_NEW. if I remove the nlmsghdr struct I can get a clean build without a warning, but still am a bit confused.
here is an updated patch let me know if it still needs work.. or if it's legit I can resend this.
