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:

---

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.

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.

---

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-v4-hc using the DM9102 driver:

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

/dev/io-net

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