devn-epic.so

Driver for SMC-9432 (EPIC) Ethernet adapters

Syntax:

io-net -d epic [option[,option ...]] ... &

Options:

Use commas (,) to separate the options (not spaces).

connector=0|1|3

Network cable connector type:

0

BNC

1

UTP

3

FIBER

did=0xXXXX

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

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.

mac=XXXXXXXXXXXX

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

mmap

Use memory mapped registers. The default is IO mapped.

mru=X

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.

priority

Priority of the driver thread. The default is 21.

promiscuous

Enable promiscuous mode. The default is off.

receive=num

Set the number of receive descriptors. The default is 64.

single

Use this option if you have multiple Epic cards in your system and want to configure them differently. The single option tells the driver to stop after configuring the first Epic card it finds. The order of the search cannot be determined because it depends on the PCI server and PCI BIOS used. After the first card has been configured, when the driver is invoked again, it will find and configure the next card in order, and so on until all Epic cards have been configured. The default is to enable all Epic cards found.

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

Set the number of transmit descriptors. The default is 128.

verbose

Be verbose.

vid=0xXXXX

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

Description:

The devn-epic.so driver controls SMC-9432 (EPIC) Ethernet adapters.

Examples:

Start io-net using the EPIC driver and the full TCP/IP stack:

io-net -d epic verbose,speed=10,duplex=0 -p tcpip
ifconfig en0 10.184
