de - DEC DC21x4x Ethernet device driver

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.
