devn-ne2000.so

Driver for NE-2000-compatible Ethernet adapters

Syntax:

io-pkt-variant -d ne2000 [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.

---

did=0xXXXX

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

ioport=num

I/O port of the interface. The port parameter must be a hex address (e.g. 0x320). The default is automatically detected on supported hardware (but see caution below).

irq=num

IRQ of the interface. The default is automatically detected on supported hardware (but see caution below).

mac=XXXXXXXXXXXX

MAC address of the controller. The default 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 the supported hardware.

promiscuous

Enable promiscuous mode. The default is off.

tmem=name

Name for typed memory.

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

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

width=8|16

I/O access width (8 or 16 bits). The default is automatically detected on supported hardware.

Description:

The devn-ne2000.so driver controls NE-2000-compatible Ethernet adapters.

---

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.

---

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 NE-2000 driver:

io-pkt-v4-hc -d ne2000 ioport=0x320,irq=11
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*.

Caveats:

If you're running a PCMCIA NE2000-compatible adapter, you may need to specify the -w8 command-line option of devp-pccard.
