028 * This option specifies policy filters for non-local source routing.
029 * The filters consist of a list of IP addresses and masks which specify
030 * destination/mask pairs with which to filter incoming source routes.
031 * 
032 * Any source routed datagram whose next-hop address does not match one
033 * of the filters should be discarded by the client.
034 * 
035 * The code for this option is 21.  The minimum length of this option is
036 * 8, and the length MUST be a multiple of 8.
