IBM/National Semiconductor PCMCIA Ethernet device driver
|
1997-01-20 10:18:54 +01:00
|
|
|
.Sh SYNOPSIS
|
|
|
|
|
.Cd "device ze0 at isa? port 0x300 net irq 5 iomem 0xd8000 vector zeintr"
|
|
|
|
|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver provides support for the IBM/National Semiconductor based PCMCIA
|
|
|
|
|
Ethernet controller. This includes the IBM Credit Card Adapter I and II
|
|
|
|
|
for the IBM Thinkpad, and the National `InfoMover' NE4100 PCMCIA card.
|
|
|
|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver is based on the device driver for National Semiconductor DS8390
|
|
|
|
|
Ethernet adapter.
|
|
|
|
|
.Sh DIAGNOSTICS
|
|
|
|
|
.Bl -diag
|
|
|
|
|
.It "ze%d: device timeout, isr=%02x, imr=%02x, imask=%04x"
|
|
|
|
|
The device has stopped responding to the network, or there is a problem with
|
|
|
|
|
the network connection (cable).
|
|
|
|
|
.It "ze%d: shared memory corrupt - invalid packet length %d"
|
|
|
|
|
This error is sometimes seen on early revisions of the Ethernet driver chip
|
|
|
|
|
under high load -- the byte order of the length gets switched.
|

.Sh CAVEATS
|
|
|
|
|
This driver is only known to work with IBM Credit Card Adapter for Ethernet,
|
|
|
|
|
but could probably work with other PCMCIA cards also, if it were modified
|
|
|
|
|
to get the locations of the PCMCIA configuration option register (COR)
|
|
|
|
|
by parsing the configuration tuples, rather than by hard-coding in
|
|
|
|
|
the value expected by IBM's card.
|
|
|
|
|
.Sh BUGS
|
|
|
|
|
Currently the driver does not support multicast.

The

|
|
|

.Sh AUTHORS
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
device driver was written by Keith Moore.
|
|
|
|
|
It is based on work originally by David Greenman, where
|
|
|
|
|
Keith made PCMCIA modifications and additions.
|
|
|
|
|
It was adapted for FreeBSD 1.1.5 by Jordan Hubbard.
