mac_ring_info

- ring information data structure

Synopsis

#include <sys/mac_provider.h>

Interface Level

Solaris architecture specific (Solaris DDI)

Description

The mac_ring_info structure is used by a network device driver to describe it's RX and TX rings. The structure is used as an argument to the mr_rget(9E) driver entry point when querying the ring.

mri_driver

Filled by the driver as handle to the driver's ring structure.

mri_start

The driver entry point for starting a driver's ring.

mri_stop

The driver entry point for stopping a driver ring.

mri_stat

The driver entry point for getting statistics for ring.

mrii_tx

The driver entry point for transmitting packet for TX rings.

mri_poll

The driver entry point for polling RX ring for packets.

mri_flags

A set of flags for describing ring behavior.

mri_intr_ddi_handle

The DDI interrupt handle associated with the interrupt for this ring.

mri_intr_enable

For RX rings, this driver entry point will enable interrupts again and transition the driver polling to interrupt mode.

mri_intr_disable

For RX rings, this driver entry point will disable interrupts and place the driver into polling mode.
