SYNOPSIS

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


.Cd "device de"

Alternatively, to load the de driver 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 an 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
  • Cogent EM100FX and EM440TX
  • Corega FastEther PCI-TX
  • D-Link DFE-500TX
  • DEC DE435, DE425, 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.

CAVEATS

Since the 21040 is available on both EISA and PCI boards, one must be careful in how one defines the 21040 in the kernel config file.
