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 an in particular the -m flag to list the sup‐
      ported 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.
