devn-via-rhine.so

Driver for VIA Rhine Network Interface Cards

Syntax:

io-pkt-variant -d via-rhine [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

deviceindex=0xXXXX

Only attach to a device with this PCI index.

did=0xXXXX

Device ID. The default is automatically detected on supported hardware.

dma=num

DMA channel.

duplex=0|1

Half (0) or full (1) duplex mode. The default is automatically detected on supported hardware. If you specify duplex, specify speed as well; if duplex alone is specified, it is ignored and both speed and duplex are auto-negotiated.

iftype=num

Interface type (from <net/if_types.h>). The default is IFT_ETHER.

iorange=0xXXXXXXXX

The IO base address.

irq=num

IRQ of the interface.

lan=num

LAN number. The default is 0.

mac=XXXXXXXXXXXX

MAC address of controller. The default is automatically detected on supported hardware.

media=num

Media type (from <hw/nicinfo.h>). The default is NIC_MEDIA_802_3

memrange=0xXXXXXXXX

Register base physical memory address.

mru=num

Maximum receive unit. The default is 1514.

mtu=X

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.

pci=0xXXXX

PCI index of the controller. The default is automatically detected on supported hardware.

phy=num

Address of the connected PHY device.

priority=N

Priority of the driver event thread. The default is 21.

promiscuous=0|1

If set to 1, enable the driver to pass all data packets received, regardless of address. The default is 0.

receive=X

Number of receive descriptors/buffers. The default is 64.

speed=10|100

Media data rate (10Mbit or 100Mbit operation). The default is automatically detected on supported hardware. If you specify speed, specify duplex as well; if speed alone is specified, the specified speed will be correctly set, but duplex will default to half (0).

transmit=num

Number of transmit descriptors/buffers. The default is 128.

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 output goes to slogger, invoke sloginfo to view.

vid=0xXXXX

Vendor ID of the controller. The default is automatically detected on supported hardware.

Description:

The devn-via-rhine.so driver controls VIA Rhine Network Interface Cards (NICs). This is a legacy io-net driver; its interface names are in the form enX, where X is an integer.

---

If the device enumerators (see enum-devices) don't recognize your device, try explicitly specifying the device ID with the did option when you start the 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 VIA Rhine NIC driver:

io-pkt-v4-hc -d via-rhine
ifconfig en0 10.1.0.184

/dev/io-net

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