490 * dladm_stat_table has one entry for each supported stat. ds_querystat returns
491 * a chain of 'stat entries' for the queried stat.
492 * Each stat entry has set of identifiers (ids) and an object containing actual
493 * stat values. These stat entry objects are chained together in a linked list
494 * of datatype dladm_stat_chain_t. Head of this list is returned to the caller
495 * of dladm_link_stat_query.
496 *
497 * One node in the chain is shown below:
498 *
499 * -------------------------
500 * | dc_statentry |
501 * | -------------- |
502 * | | ids | |
503 * | -------------- |
504 * | | stat fields | |
505 * | -------------- |
506 * -------------------------
507 * | dc_next ---------|------> to next stat entry
508 * -------------------------
509 *
510 * In particular, for query DLADM_STAT_RX_LANE, dc_statentry carries pointer to
511 * object of type rx_lane_stat_entry_t.
512 *
513 * dladm_link_stat_query_all returns similar chain. However, instead of storing
514 * stat fields as raw numbers, it stores those as chain of <name, value> pairs.
515 * The resulting structure is depicted below:
516 *
517 * -------------------------
518 * | dc_statentry |
519 * | -------------- | ---------------
520 * | | nv_header | | | name, val |
521 * | -------------- | ---------------
522 * | | nve_stats---|----|-->| nv_nextstat--|---> to next name, val pair
523 * | -------------- | ---------------
524 * -------------------------
525 * | dc_next ---------|------> to next stat entry
526 * -------------------------
