include this in all kernels. Declare some const *intrq_present variables that can be checked by a module prior to using *intrq to queue data. Make the if_tun module capable of processing atm, ip, ip6, ipx, natm and netatalk packets when TUNSIFHEAD is ioctl()d on. Review not required by: freebsd-hackers
