NAME
de — DEC DC21x4x Ethernet device driverSYNOPSIS
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:
- Adaptec ANA-6944/TX

- 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 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.
