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.

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.
