devnp-e1000.so

Driver for Intel Gigabit Ethernet controllers

Syntax:

io-pkt-variant -d e1000 [option[,option ...]] ... &

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

Runs on:

Neutrino

Options:


Note: Use commas, not spaces, to separate the options.

did=0xXXXX
Detect only devices with this specific 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 duplex alone is specified, it is ignored and both speed and duplex are auto-negotiated.

You can also use ifconfig -m and ifconfig wmX media to set this.

irq=N
IRQ of the interface. The default is automatically detected on supported hardware.
mac=XXXXXXXXXXXX
The MAC address of the controller. The default is automatically detected on supported hardware.
mtu=N
The maximum transmission unit. The default is 1514.
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 only devices at this specific PCI index.
priority=N
The priority of the driver's event-handler thread (default 21).
promiscuous
Enable reception of all packets.
receive=num
The number of receive descriptors; the default is 64.
speed=N
Force the link speed (specified in Mbits/second). If you specify speed, specify duplex as well; if speed alone is specified, the specified speed is correctly set, but duplex defaults to half (0).

You can also use ifconfig -m and ifconfig wmX media to set this.

transmit=N
The number of transmit descriptors; the default is 128.
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 devnp-e1000.so driver manages all current Intel Gigabit devices. This is a native io-pkt driver; its interface names are in the form wmX, where X is an integer.

The devnp-e1000.so and devnp-i82544.so drivers are similar:


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 wmX

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 using the devnp-e1000.so driver and the full TCP/IP stack:

io-pkt -d e1000
ifconfig wm0 192.168.0.10
