de — DEC DC21x4x Ethernet device driver

       The de device driver was written by Matt Thomas.  This manual page was written by David E. O'Brien.

Debian                                          October 24, 2018                                           DE(4)

       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.

       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.

de%d:wakingdevicefromsleep/snoozemode  The 21041 and 21140A chips support suspending the operation
       of the card.

       de%d:error:desiredIRQof%ddoesnotmatchdevice'sactualIRQof%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:notconfigured;limitof%dreachedorexceeded  There is a limit of 32 de  devices  allowed  in  a
       single machine.

       de%d:notconfigured;21040pass2.0required(%d.%dfound)de%d:notconfigured;21140pass1.1required(%d.%dfound)  Certain revisions of the chipset are not
       supported by this driver.

       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

       To compile this driver into the kernel, place the following line in your kernel configuration file:

             devicede

       Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

             if_de_load="YES"
