gld_stats Structure

After calling gldm_get_stats(), a GLDv2-based driver uses the (gld_stats) structure to communicate statistics and state information to GLDv2. See the gld(9E) and gld(7D) man pages. The members of this structure, having been filled in by the GLDv2-based driver, are used when GLDv2 reports the statistics. In the tables below, the name of the statistics variable reported by GLDv2 is noted in the comments. See the gld(7D) man page for a more detailed description of the meaning of each statistic.

Drivers must not make any assumptions about the length of this structure. The structure length might vary in different releases of the Solaris OS, GLDv2, or both. Structure members private to GLDv2, which are not documented here, should not be set or be 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_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_freq_error          /* freq_errors */

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_ring_op;        /* mac_ring_ops */

Most of the above statistics variables are counters that denote the number of times that the particular event was observed. The following statistics do not represent the number of times:

glds_speed

Estimate of the interface's current bandwidth in bits per second. This object should contain the nominal bandwidth for those interfaces that do not vary in bandwidth or where an accurate estimate cannot be made.

glds_media

Type of media (wiring) or connector used by the hardware. The following media names are supported:

• GLDM_AUI

• GLDM_BNC

• GLDM_TP

• GLDM_10BT

• GLDM_100BT

• GLDM_100BTX

• GLDM_100BT4

• GLDM_RING4

• GLDM_RING16

• GLDM_FIBER

• GLDM_PHYMII

• GLDM_UNKNOWN

glds_duplex

Current duplex state of the interface. Supported values are GLD_DUPLEX_HALF and GLD_DUPLEX_FULL. GLD_DUPLEX_UNKNOWN is also allowed.
