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.conf(5):
if_de_load="YES"
DEPRECATION NOTICE
The de driver is not present in FreeBSD 13.0 and later. See https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more information.
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.

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.
