devn-epic.so

Driver for SMC 9432 (EPIC) Ethernet adapters

Syntax:

io-pkt-variant -d epic [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|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 can't 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. The output goes to slogger; invoke sloginfo to view it.

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. 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-v6-hc using the EPIC driver:

io-pkt-v6-hc -d epic verbose,speed=10,duplex=0
ifconfig en0 10.1.0.184
