gld_stats - Generic LAN Driver statistics data structure

#include <sys/gld.h>

illumos architecture specific (illumos DDI). The Generic LAN Driver (GLD) statistics (gld_stats) structure is used to communicate statistics and state information from a GLD-based driver to GLD when returning from a driver's gldm_get_stats() routine as discussed in gld(9E) and gld(4D). The members of this structure, filled in by the GLD-based driver, are used when GLD reports the statistics. In the tables below, the name of the statistics variable reported by GLD is noted in the comments. See gld(4D) for a more detailed description of the meaning of each statistic.

Drivers can make no assumptions about the length of this structure, which might be different in different releases of illumos and/or GLD. Structure members private to GLD, not documented here, should not be set or read by the device specific driver.

The following structure members are defined for all media types:

uint64_t glds_speed; /* ifspeed */
uint32_t glds_media; /* media */
uint32_t glds_intr; /* intr */
uint32_t glds_norcvbuf; /* norcvbuf */
uint32_t glds_errrcv; /* ierrors */
uint32_t glds_errxmt; /* oerrors */
uint32_t glds_missed; /* missed */
uint32_t glds_underflow; /* uflo */
uint32_t glds_overflow; /* oflo */

The following structure members are defined for media type DL_ETHER:

uint32_t glds_frame; /* align_errors */
uint32_t glds_crc; /* fcs_errors */
uint32_t glds_duplex; /* duplex */
uint32_t glds_nocarrier; /* carrier_errors */
uint32_t glds_collisions; /* collisions */
uint32_t glds_excoll; /* ex_collisions */
uint32_t glds_xmtlatecoll; /* tx_late_collisions */
uint32_t glds_defer; /* defer_xmts */
uint32_t glds_dot3_first_coll; /* first_collisions */
uint32_t glds_dot3_multi_coll; /* multi_collisions */
uint32_t glds_dot3_sqe_error; /* sqe_errors */
uint32_t glds_dot3_mac_xmt_error; /* macxmt_errors */
uint32_t glds_dot3_mac_rcv_error; /* macrcv_errors */
uint32_t glds_dot3_frame_too_long; /* toolong_errors */
uint32_t glds_short; /* runt_errors */

The following structure members are defined for media type DL_TPR:

uint32_t glds_dot5_line_error /* line_errors */
uint32_t glds_dot5_burst_error /* burst_errors */
uint32_t glds_dot5_signal_loss /* signal_losses */
uint32_t glds_dot5_ace_error /* ace_errors */
uint32_t glds_dot5_internal_error /* internal_errors */
uint32_t glds_dot5_lost_frame_error /* lost_frame_errors */
uint32_t glds_dot5_frame_copied_error /* frame_copied_errors */
uint32_t glds_dot5_token_error /* token_errors */
uint32_t glds_dot5_freq_error /* freq_errors */

Note -

The following structure members are defined for media type DL_FDDI:

uint32_t glds_fddi_mac_error; /* mac_errors */
uint32_t glds_fddi_mac_lost; /* mac_lost_errors */
uint32_t glds_fddi_mac_token; /* mac_tokens */
uint32_t glds_fddi_mac_tvx_expired; /* mac_tvx_expired */
uint32_t glds_fddi_mac_late; /* mac_late */
uint32_t glds_fddi_mac_ring_op; /* mac_ring_ops */

Note -

Most of the above statistics variables are counters denoting the number of times the particular event was observed. Exceptions are: glds_speed

glds_media glds_duplex gld (4D), gld (9E), gld (9F), gld_mac_info (9S)
