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 pro-
         grammed 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 supported media types for your par-
         ticular card.
         The old “ifconfig linkN” method of configuration is not supported.

         de%d: waking device from sleep/snooze mode The 21041 and 21140A chips support suspending the oper-
         ation 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.
