* The &rte contains information specific to the route (preference, protocol
* metrics, time of last modification etc.) and a pointer to a &rta structure
* (see the route attribute module for a precise explanation) holding the
* remaining route attributes which are expected to be shared by multiple
* routes in order to conserve memory.
* The &rte contains information about the route. There are net and src, which
* together forms a key identifying the route in a routing table. There is a
* pointer to a &rta structure (see the route attribute module for a precise
* explanation) holding the route attributes, which are primary data about the
* route. There are several technical fields used by routing table code (route
* id, REF_* flags), There is also the pflags field, holding protocol-specific
* flags. They are not used by routing table code, but by protocol-specific
* hooks. In contrast to route attributes, they are not primary data and their
* validity is also limited to the routing table.
*
* There are several mechanisms that allow automatic update of routes in one
* routing table (dst) as a result of changes in another routing table (src).
