- * To retrieve the neighbour tables send RTM_GETNEIGHTBL with the

- * size limits on systems with many interfaces. The first message
- * in the sequence transports all not device specific data such as
- * statistics, configuration, and the default parameter set.
- * This message is followed by 0..n messages carrying device
- * specific parameter sets.
- * Although the ordering should be sufficient, NDTA_NAME can be
- * used to identify sequences. The initial message can be identified
- * by checking for NDTA_CONFIG. The device specific messages do
- * not contain this TLV but have NDTPA_IFINDEX set to the
- * corresponding interface index.
- *
- * To change neighbour table attributes, send RTM_SETNEIGHTBL
- * with NDTA_NAME set. Changeable attribute include NDTA_THRESH[1-3],
- * NDTA_GC_INTERVAL, and all TLVs in NDTA_PARMS unless marked
- * otherwise. Device specific parameter sets can be changed by
- * setting NDTPA_IFINDEX to the interface index of the corresponding
