505 * Neighbour tables specific messages.
506 *
507 * To retrieve the neighbour tables send RTM_GETNEIGHTBL with the
508 * NLM_F_DUMP flag set. Every neighbour table configuration is
509 * spread over multiple messages to avoid running into message
510 * size limits on systems with many interfaces. The first message
511 * in the sequence transports all not device specific data such as
512 * statistics, configuration, and the default parameter set.
513 * This message is followed by 0..n messages carrying device
514 * specific parameter sets.
515 * Although the ordering should be sufficient, NDTA_NAME can be
516 * used to identify sequences. The initial message can be identified
517 * by checking for NDTA_CONFIG. The device specific messages do
518 * not contain this TLV but have NDTPA_IFINDEX set to the
519 * corresponding interface index.
520 *
521 * To change neighbour table attributes, send RTM_SETNEIGHTBL
522 * with NDTA_NAME set. Changeable attribute include NDTA_THRESH[1-3],
523 * NDTA_GC_INTERVAL, and all TLVs in NDTA_PARMS unless marked
524 * otherwise. Device specific parameter sets can be changed by
525 * setting NDTPA_IFINDEX to the interface index of the corresponding
526 * device.
