devn-crys8900.so

Driver for Crystal 89xx Ethernet adapters

Syntax:

io-pkt-variant -d crys8900 [option[,option ...]] ...

where variant is one of v4, v4-hc, or v6-hc.

Runs on:

Neutrino

Options:


Note: Use commas, not spaces, to separate the options.

connector=0|1|2|3
Network cable connector type:
0
BNC
1
UTP
2
AUI
3
FIBER
dma=num
The DMA channel.
duplex=0|1
Half (0) or full (1) duplex mode.
iftype=num
Interface type (from <net/if_types.h>). The default is IFT_ETHER.
iorange=0xXXXXXXXX
I/O base address.
irq=num
IRQ of the interface. The default is automatically detected on supported hardware (but see caution below).
lan=num
LAN number. The default is 0.
mac=XXXXXXXXXXXX
MAC address of the controller. The default is automatically detected on supported hardware.
media=num
Media type (from <hw/nicinfo.h>). The default is NIC_MEDIA_802_3.
mru=num
Maximum receive unit. The default is 1514.
mtu=num
Maximum transmission unit. The default (1514) is automatically detected on supported hardware.
nomulticast
Disables the driver from sending or receiving multicast packets. By default, multicast is enabled.
priority=N
Priority of the driver event-thread. The default is 21.
promiscuous
Enable promiscuous mode. The default is off.
uptype=name
Interface name. The default is "en".
verbose
verbose=num
Be verbose. Specify num for more verbosity (num can be 1-4, the higher the number, the more detailed the output). The default is 0. The output goes to slogger, invoke sloginfo to view.

Description:

The devn-crys8900.so driver controls Crystal 89xx Ethernet adapters. This is a legacy io-net driver; its interface names are in the form enX, where X is an integer.


Caution: This driver can't always detect the correct irq and ioport options, especially for ISA devices. To be sure, always specify irq and ioport when using this driver.

Some devices support hardware checksums, although some might do so in only one direction; to determine if your device does, type:

ifconfig enX

and look for the following in the list of supported options:

You can then use ifconfig to enable or disable whichever of these options your device supports.

Examples:

Start io-pkt-v4-hc using the Crystal 89xx driver: stack:

io-pkt-v4-hc -d crys8900
ifconfig en0 10.1.0.184

Files:

/dev/io-pkt
The directory where, by default, drivers and protocol modules add entries. For more information, see the documentation for io-pkt*.
