de -- DEC DC21x4x Ethernet device driver
The de driver provides support for the Ethernet adapters based on the
Digital Equipment DC21x4x based self-contained Ethernet and Fast Ethernet
+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.
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.
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.
