- * 15-Feb-1997: Major changes to allow graphs for firewall rules.
- * Paul Russell <Paul.Russell@rustcorp.com.au> and
- * Michael Neuling <Michael.Neuling@rustcorp.com.au>
- * 2-Nov-1997: Changed types to __u16, etc.
- * Removed IP_FW_F_TCPACK & IP_FW_F_BIDIR.
- * Added inverse flags field.
- * Removed multiple port specs.
