`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-pkt: 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.
