`devn-i82544.so`

Driver for Intel 82540, 82544, 82545, 82546, and 82547 Gigabit Ethernet LAN adapters

Syntax:

io-net -d i82544 [option[,option ...]] ... &

Options:

Use commas (,) to separate the options (not spaces).

did: Only detect 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.
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.
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.
pci: Only detect devices 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.
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 speed alone is specified, the specified speed is correctly set, but duplex defaults to half (0).
transmit=N: Set 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.
vid: Only detect devices with this specific PCI Vendor ID.

Description:

The devn-i82544.so driver manages the Intel 82540, 82544, 82545, 82546, and 82547 Gigabit Ethernet LAN adapters.

Examples:

Start io-net using the devn-i82544.so driver and the full TCP/IP stack:

io-net -d i82544 -p tcpip
ifconfig en0 10.184

Files:

/dev/io-net: The directory where, by default, drivers and protocol modules add entries. For more information, the documentation for io-net.
