NAME
de - DEC DC21x4x Ethernet device driver

SYNOPSIS
device de0

DESCRIPTION
The de driver provides support for the Ethernet adapters based on the Digital Equipment DC21x4x based self-contained Ethernet chips.

It supports the DEC PCI DE435 card, DEC EISA DE425, DEC DE450, SMC 9332, ZNYX ZX314, and others based on the 21040 and 21041 Ethernet controllers or the 21140[A] Fast 100Base-T Ethernet controller.

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.

CAVEATS
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.

BUGS
Currently the driver does not support multicast.
