 * the interface over which packets to this net can be sent,
 * and the associated type table tells whether or not the
 * connection is direct or through a gateway; if so, we get
 * the address of the gateway from the gateway address tables.
 * The assocated gateway table is used for entries that
 * are updated dynamically by the routing info received from the
 * net; see the CHAOS routing algorithm description.
