`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
