NAME

de – DEC DC21x4x Ethernet device driver

CONTENTS

SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configuration file: device de

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

if_de_load="YES"

DESCRIPTION

The de driver provides support for the Ethernet adapters based on the Digital Equipment DC21x4x based self-contained Ethernet and Fast Ethernet chips.

The de driver supports the following media types:
autoselect Enable autoselection of the media type and options
10baseT/UTP Set 10Mbps operation on the 10baseT port
10base2/BNC Set 10Mbps operation on the BNC port
10base5/AUI Set 10Mbps operation on the AUI port
100baseTX Set 100Mbps (Fast Ethernet) operation
100baseFX Set 100Mbps operation
100baseT4 Set 100Mbps operation (4-pair cat-3 cable)

The de driver supports the following media options:
full-duplex Set full duplex operation

Note that the media types available depend on the particular card in use. Some cards are explicitly programmed to a particular media type by a setup utility and are not changeable.

Use the ifconfig(8) command and in particular the -m flag to list the supported media types for your particular card.

The old "ifconfig linkN" method of configuration is not supported.

HARDWARE

Adapters supported by the de driver include:

DIAGNOSTICS

de%d: waking device from sleep/snooze mode The 21041 and 21140A chips support suspending the operation of the card.
de%d: error: desired IRQ of %d does not match device's actual IRQ of %d The device probe detected that the board is configured for a different interrupt than the one specified in the kernel configuration file.
de%d: not configured; limit of %d reached or exceeded There is a limit of 32 de devices allowed in a single machine.
de%d: not configured; 21040 pass 2.0 required (%d.%d found)
de%d: not configured; 21140 pass 1.1 required (%d.%d found)
  Certain revisions of the chipset are not supported by this driver.
