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 Ether-
     net 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:

     o   Adaptec ANA-6944/TX
     o   Cogent EM100FX and EM440TX
     o   Corega FastEther PCI-TX
     o   D-Link DFE-500TX
     o   DEC DE435, DEC DE450, and DEC DE500
     o   ELECOM LD-PCI2T, LD-PCITS
     o   I-O DATA LA2/T-PCI
     o   SMC Etherpower 8432, 9332 and 9334
     o   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 differ-
     ent 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.
