508 | * Neighbour tables specific messages. | |
509 | * | |
510 | * To retrieve the neighbour tables send RTM_GETNEIGHTBL with the | |
511 | * NLM_F_DUMP flag set. Every neighbour table configuration is | |
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. | |
