    sys/netinet          ip_fw2.c 
  When doing matching based on dst_ip/src_ip make sure we are really looking
  on an IPv4 packet as these variables are uninitialized if not.  This used to
  allow arbitrary IPv6 packets depending on the value in the uninitialized
  Some opcodes (most noteably O_REJECT) do not support IPv6 at all right now.

  Security:       IPFW might pass IPv6 packets depending on stack contents.
