24 host_id - see knet_host_add(3)

26 link_id - see knet_link_set_config(3)
27
28 status - pointer to knet_link_status struct
29
30 struct_size - max size of knet_link_status - allows library to add
31 fields without ABI change. Returned structure will be truncated to this
32 length and .size member indicates the full size.
