devn-i82544.so

Driver for Intel Gigabit Ethernet LAN adapters and I/O Controller Hubs

Syntax:

io-pkt-variant -d /lib/dll/devn-i82544.so
    [option[,option ...]] ... &

where variant is one of v4, v4-hc, or v6-hc.

Note: If you don't specify the full path to devn-i82544.so, io=pkt* starts devnp-i82544.so.

Runs on:

Neutrino

Options:

Note: Use commas, not spaces, to separate the options.
did=0xXXXX
Detect only devices with the given PCI 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 you specify duplex alone, it's ignored, and both speed and duplex are auto-negotiated.
flowcontrol=0|1
Disable (0) or enable (1) hardware flow control.
irq=N
IRQ of the interface. The default is automatically detected on supported hardware.
lan=num
The LAN number. The default is 0.
mac=XXXXXXXXXXXX
MAC address of controller. The default is automatically detected on supported hardware.
mtu=X
Maximum transmission unit. The default (1514) is automatically detected on supported hardware.
nomulticast
Disable the driver from sending or receiving multicast packets. By default, multicast is enabled.
pauseignore
Ignore pause frames with respect to full duplex flow control.
pausesuppress
Suppress pause frames with respect to full duplex flow control.
pci=0xXXXX
Detect devices only at this specific PCI index.
priority=X
Priority of the driver's event-handler 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 on PPC, and 128 on other platforms.
speed=10|100|1000
Media data rate (10Mbit, 100Mbit, or Gigabit operation). The default is automatically detected on supported hardware. If you specify speed, specify duplex as well; if you specify speed alone, the specified speed is correctly set, but duplex defaults to half (0).
transmit=num
Set the number of transmit descriptors. The default is 64 on PPC, and 512 on other platforms.
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
Detect only devices with this specific PCI vendor ID.

Description:

The devn-i82544.so driver manages the Intel 82540, 82541, 82542, 82543, 82544, 82545, 82546, 82547, 82571, 82572, and 82573 Gigabit Ethernet LAN adapters, and the ICH8 and ICH9 I/O Controller Hubs. This is a legacy io-net driver; its interface names are in the form enX, where X is an integer.

Note: 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:

You can then use ifconfig to enable or disable whichever of these options your device supports.

Examples:

Start io-pkt-v4-hc using the devn-i82544.so driver: 

io-pkt-v4-hc -d /lib/dll/devn-i82544.so
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*
