     de -- DEC DC21x4x Ethernet device driver

SYNOPSIS    [Toc]    [Back]

     device de

DESCRIPTION    [Toc]    [Back]

     The de driver provides support for the Ethernet adapters based on the
     Digital Equipment DC21x4x based self-contained Ethernet and Fast Ethernet
     chips, including:

	   +o   Asante
	   +o   Cogent EM100FX and EM440TX
	   +o   Corega FastEther PCI-TX
	   +o   DEC DE435, DE425, 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

     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 supported
 media types for your particular card.

     The old ``ifconfig linkN'' method of configuration is not supported.

DIAGNOSTICS    [Toc]    [Back]

     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.

CAVEATS    [Toc]    [Back]

     Since the 21040 is available on both EISA and PCI boards, one must be
     careful in how defines the 21040 in the kernel config file.
