| | gld_stats - Generic LAN Driver statistics data structure |
SYNOPSIS
| |
Solaris architecture specific (Solaris 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(7D). 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(7D) 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 Solaris and/or GLD. Structure members private to GLD, not documented here, should not be set or read by the device specific driver.

Most of the above statistics variables are counters denoting the number of times the particular event was observed. Exceptions are:
-
glds_speed
- An estimate of the interface's current bandwidth in bits per second. For interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this object should
contain the nominal bandwidth.
-
glds_media
- The type of media (wiring) or connector used by the hardware. Currently supported media names include GLDM_AUI, GLDM_BNC, GLDM_TP, GLDM_10BT, GLDM_100BT, GLDM_100BTX, GLDM_100BT4, GLDM_RING4, GLDM_RING16, GLDM_FIBER, and GLDM_PHYMII. GLDM_UNKNOWN can also be specified.
-
glds_duplex
- Current duplex state of the interface. Supported values are GLD_DUPLEX_HALF and GLD_DUPLEX_FULL. GLD_DUPLEX_UNKNOWN can also be specified.
