[bgpd] Trim memory usage of BGP routes
2007-05-03 Paul Jakma <paul.jakma@sun.com> * bgp_route.h: (struct info) Move less frequently used fields to a lazily allocated struct info_extra. Export bgp_info_extra_get * bgp_route.c: (bgp_info_extra_new) allocate extra (bgp_info_extra_free) Free damp info and the info_extra. (bgp_info_extra_get) Retrieve the info_extra of a struct info, allocating as required. (generally) adjust to use info->extra * bgp_damp.c: (generally) use bgp_info_extra_get to access dampinfo * bgp_attr.h: Move rarely allocated attributes from struct attr to a struct attr_extra, for a substantial saving in size of struct attr. * bgp_attr.c: (bgp_attr_extra_{new,free}), new, self-explanatory. (bgp_attr_extra_get) Get the attr_extra for a given struct attr, allocating it if needs be. (bgp_attr_dup) Shallow copy the struct attr and its attr_extra. (generally) adjust to know about attr->extra. * bgp_debug.c: (bgp_dump_attr) ditto * bgp_vty.c: (show_bgp_memory) print attr and info extra sizes. * bgp_nexthop.c: (generally) adjust to know about attr->extra and info->extra. * bgp_{packet,routemap,snmp,zebra}.c: ditto * lib/memtypes.c: Add MTYPE_ATTR_EXTRA and MTYPE_BGP_ROUTE_EXTRA
