devn-speedo.so

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

Syntax:

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

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

---

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

---

Runs on:

Neutrino

Options:

---

Use commas, not spaces, to separate the options.

---

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.

probe_phy=0|1

Select whether or not to probe the PHY at regular intervals. For the default value of 0, the PHY is polled only at regular intervals when the interface is down or doesn't receive any packets over the polling interval.

If you specify 1, the PHY is always probed at regular intervals to see if the duplex and/or speed of the connection has changed. This results in reduced performance due to lost packets under heavy load, but guarantees the NIC is always in sync with the media.

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. 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-v6-hc using the devn-speedo.so driver:

io-pkt-v6-hc -d /lib/dll/devn-speedo.so
ifconfig en0 10.1.0.184

For the second instance of the device in the system, start io-pkt-v6-hc using the devn-speedo.so driver. Use increased verbosity and override the default #MAC address:

io-pkt-v6-hc -d /lib/dll/devn-speedo.so verbose,idx1:mac=00:03:02:01:00:00
ifconfig en0 10.1.0.184
