devn-pegasus.so

Driver for SMC EZ Connect and other USB Ethernet adapters based on the Pegasus chipset

Syntax:

io-pkt-variant -d pegasus [option[,option ...]] ...

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

Runs on:

Neutrino

Options:

---

Use commas, not spaces, to separate the options.

---

duplex=0|1

Half (0) or full (1) duplex mode.

iftype=num

Interface type (from <net/if_types.h>). The default is IFT_ETHER.

lan=num

LAN number. The default is 0.

mac=XXXXXXXXXXXX

MAC address of the controller. You must set the MAC address for this controller.

media=num

Media type (from <hw/nicinfo.h>). The default is NIC_MEDIA_802_3.

mru=num

Maximum receive unit. The default is 1514.

mtu=num

Maximum transmission unit. The default (1514) is automatically detected on supported hardware.

nomulticast

Disable multicast support.

path

Set the device name. The default is /dev/usbenet0.

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.

promiscuous

Enable promiscuous mode. The default is off.

receive=num

Set the number of receive descriptors/buffers. The default is 5.

speed=10|100

Force media data rate (10Mbit or 100Mbit 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 will be correctly set, but duplex will default to half (0).

transmit=num

Set the number of transmit descriptors/buffers. The default is 10.

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 default is 0. The output goes to slogger; invoke sloginfo to view it.

wait=num

Wait num seconds for the USB stack. The default wait time is 60 seconds.

Description:

The devn-pegasus.so driver controls the SMC EZ Connect USB Ethernet adapter and other USB Ethernet adapters based on the Pegasus chipset. This is a legacy io-net driver; its interface names are in the form enX, where X is an integer.

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 Pegasus driver:

io-pkt-v6-hc -d pegasus
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*.

Caveats:

Start the USB stack before using this driver (see devu-ohci.so or devu-uhci.so)
