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:

---

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.

---

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:

• ip4csum, ip4csum-rx, ip4csum-tx
• tcp4csum, tcp4csum-rx, tcp4csum-tx
• tcp6csum, tcp6csum-rx, tcp6csum-tx
• udp4csum, udp4csum-rx, udp4csum-tx
• udp6csum, udp6csum-rx, udp6csum-tx

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-net

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