`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
