* Neighbour tables specific messages.
|
|
*
|
|
* To retrieve the neighbour tables send RTM_GETNEIGHTBL with the
|
|
* NLM_F_DUMP flag set. Every neighbour table configuration is
|
|
* spread over multiple messages to avoid running into message
|
|
* 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
|
|
* device.
