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

758 - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
759 - If neither of these three flags are set;
760 the interface is NBMA.
761
762 - IFF_MULTICAST does not mean anything special:
763 multicasts can be used on all not-NBMA links.
764 IFF_MULTICAST means that this media uses special encapsulation
765 for multicast frames. Apparently, all IFF_POINTOPOINT and
766 IFF_BROADCAST devices are able to use multicasts too.
