devn-tigon3.so

Driver for TIGON3 (BCM570X) Ethernet controller

Syntax:

io-pkt-variant -d tigon3 [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=type

The network cable connector type:

0

BNC

1

UTP

3

FIBER

The default is automatically detected on supported hardware.

did=0xXXXX

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

duplex=dup

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's ignored, and both speed and duplex are autonegotiated.

mac=XXXXXXXXXXXX

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

nomulticast

Disable the driver from sending or receiving multicast packets. By default, multicast is enabled.

pci=0xXXXX

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

priority

The priority of the driver 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.

single

In a multiple NIC environment, stop after the first detected card. Default is to enable all cards found.

speed=10|100|1000

The media data rate, in megabits per second. 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).

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 it.

vid=0xXXXX

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

Description:

The devn-tigon3.so driver is the Ethernet controller for the Broadcom BCM570X. 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 using the TIGON3 driver:

io-pkt-v4 -d tigon3 verbose
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*.
