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 set-
     up	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.

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 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.
