`devn-speedo.so`

Driver for Intel 82557, 82558, and 82559 Fast Ethernet LAN adapters

Syntax:

io-net -d speedo [[index:option[,[index:option ...]] ... &

Options:

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

did=0xXXXX: Device ID. Only attach to device with this PCI index. 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.
iftype=num: Interface type (from <net/if_types.h>). The default is IFT_ETHER.
irq=num: IRQ of the interface. The default is automatically detected on supported hardware.
lan=num: LAN number. The default is 0.
mac=XXXXXXXXXXXX: MAC address of controller. The default is automatically detected on supported hardware.
media=num: Media type (from <hw/nicinfo.h>). The default is NIC_MEDIA_802_3.
mmap: Use memory-mapped registers. The default is IO mapped.
mru=num: Maximum receive unit. The default is 1514.
mtu=num: Maximum transmission unit. The default (1514) 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 supported hardware.
phy=num: Address of the connected PHY device.
priority=N: Priority of the driver-event 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: Media data rate (10Mbit or 100Mbit operation). The default (0) is automatically detected on supported hardware. If you specify speed, specify duplex as well; if speed alone is specified, the specified speed will be correctly set, but duplex will default to half (0).
transmit=num: Set the number of transmit descriptors. The default is 128.
uptype=name: Interface name. The default is "en".
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. Only attach to devices with this PCI vendor ID. The default is automatically detected on supported hardware.

Description:

The devn-speedo.so driver manages the Intel 82557, 82558, and 82559 Fast Ethernet LAN adapters.

Examples:

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

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

For the second instance of the device in the system, start io-net using the devn-speedo.so driver and the full TCP/IP stack. Use increased verbosity and override the default #MAC address:

io-net -d speedo verbose,idx1:mac=00:03:02:01:00:00 -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.
