DEC DC21x4x Ethernet device driver
|
|
|
|
|
.Sh SYNOPSIS
|
|

|
|
.Cd "device de0"
|
|
|
|
|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver provides support for the Ethernet adapters based on the Digital
|
|
|
|
|
Equipment DC21x4x based self-contained Ethernet chips.
|
|
|
|
|
.Pp
|
|
|
|
|
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.
|
|
|
|
|
.Sh DIAGNOSTICS
|
|
|
|
|
.Bl -diag
|
|
|
|
|
.It "de%d: waking device from sleep/snooze mode"
|
1997-01-25 20:42:09 +00:00
|
|
|
The 21041 and 21140A chips support suspending the operation of the card.
|
1997-01-20 09:18:54 +00:00
|
|
|
.It "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.
|
|
|
|
|
.It "de%d: not configured; limit of %d reached or exceeded"
|
|
|
|
|
There is a limit of 32
|
|
|
|
|
.Nm
|
|
|
|
|
devices allowed in a single machine.
|
|
|
|
|
.It "de%d: not configured; 21040 pass 2.0 required (%d.%d found)"
|
|
|
|
|
.It "de%d: not configured; 21140 pass 1.1 required (%d.%d found)"
|
|
|
|
|
Certain revisions of the chipset are not supported by this driver.
|
|
|

|
|
|
|
|
.Sh 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.
|
|
|
|
|
.Sh BUGS
|
|
|
|
|
Currently the driver does not support multicast.
