NAME

de - DEC DC21x4x Ethernet device driver

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.conf5:

if_de_load="YES"

DESCRIPTION

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

The ifconfig 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 ifconfig 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 ifconfig driver include:

• Adaptec ANA-6944/TX
• Cogent EM100FX and EM440TX
• Corega FastEther PCI-TX
• D-Link DFE-500TX
• DEC DE435, DEC DE450, and DEC DE500
• ELECOM LD-PCI2T, LD-PCITS
• I-O DATA LA2/T-PCI
• SMC Etherpower 8432, 9332 and 9334
• ZNYX ZX3xx

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 ifconfig 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.
