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"

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
       •   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 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.
