devn-dm9102.so

Driver for Davicom DM9102 Ethernet adapters

Syntax:

io-pkt-variant -d dm9102 [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. These options will override auto-detected defaults.

did=0xXXXX
Device ID.
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.
lan=num
The LAN number. The default is 0.
mac=XXXXXXXXXXXX
MAC address of the controller. If no SROM is available, the MAC will default to 00:00:00:00:00:00
nomulticast
Disable multicast support.
pci=0xXXXX
PCI index of the controller.
phyaddr=num
Override the mii routines and use the specified phy address.
pktque=num
Limit the number of packets in the queue. The default is 100.
priority
Priority of the driver thread. The default is 21.
promiscuous
Enable promiscuous mode.
receive=num
Set the number of receive descriptors. The default is 64.
single
Configure and run only the first DM9102 card that is found (single instance).
speed=10|100
Media data rate (10 Mbit or 100 Mbit 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).
threshold=N
The amount of packet data that must be in the TX FIFO before transmission is initiated. The range is 0–4. The default is 3.
transmit=num
Set the number of transmit descriptors. The default is 128.
verbose
Be verbose.
vid=0xXXXX
PCI vendor ID.

Description:

The devn-dm9102 driver controls Davicom DM9102 Ethernet adapters. This is a legacy io-net driver; its interface names are in the form enX, where X is an integer.


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 enX

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-v4-hc using the DM9102 driver:

io-pkt-v4-hc -d dm9102
ifconfig en0 10.0.0.184

Files:

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