68 * Neighbour tables specific messages.
70 * To retrieve the neighbour tables send RTM_GETNEIGHTBL with the
71 * NLM_F_DUMP flag set. Every neighbour table configuration is
72 * spread over multiple messages to avoid running into message
73 * size limits on systems with many interfaces. The first message
74 * in the sequence transports all not device specific data such as
75 * statistics, configuration, and the default parameter set.
76 * This message is followed by 0..n messages carrying device
77 * specific parameter sets.
78 * Although the ordering should be sufficient, NDTA_NAME can be
79 * used to identify sequences. The initial message can be identified
80 * by checking for NDTA_CONFIG. The device specific messages do
81 * not contain this TLV but have NDTPA_IFINDEX set to the
82 * corresponding interface index.
84 * To change neighbour table attributes, send RTM_SETNEIGHTBL
85 * with NDTA_NAME set. Changeable attribute include NDTA_THRESH[1-3],
86 * NDTA_GC_INTERVAL, and all TLVs in NDTA_PARMS unless marked
87 * otherwise. Device specific parameter sets can be changed by
88 * setting NDTPA_IFINDEX to the interface index of the corresponding
89 * device.
