tun_device_t does currently not provide support for IPv6 (the ioctls for
IPv6 are quire different, and different for each platform - I did some
experiments a year ago in the tun-device-ipv6 branch).  To avoid the
buffer overflow, you could add a check for the address family in
set_address() and return FALSE if it is AF_INET6.
