- Davicom Fast Ethernet driver for Davicom DM9102A

Synopsis

/kernel/drv/sparcv9/dmfe

Description

The dmfe Ethernet device provides 100Base-TX networking interfaces using the Davicom DM9102A chip, which incorporates its own internal transceiver.

The dmfe driver functions include controller initialization, frame transmit and receive, promiscuous and multicast support, and error recovery and reporting. Multiple controllers installed within the system are supported by the driver.

The 100Base-TX standard specifies an auto-negotiation protocol to automatically select the mode and speed of operation. The internal transceiver is capable of performing auto-negotiation with the remote-end of the link (link partner) and receives the capabilities of the remote end. It selects the highest common denominator mode of operation based on the priorities. The internal transceiver also supports a forced-mode of operation under which the driver selects the operational mode.

APPLICATION PROGRAMMING INTERFACE

The /dev/dmfe cloning character-special device is used to access all Davicom DM9102A devices installed in the system.

You must send an explicit DL_ATTACH_REQ message to associate the opened stream with a particular device (ppa). The ppa ID is interpreted as an unsigned integer data type and indicates the corresponding device instance (unit) number. If the ppa field value does not correspond to a valid device instance number for this system, an error (DL_ERROR_ACK) is returned. The device is initialized on first attach and de-initialized (stopped) at last detach.

The values returned by the driver in the DL_INFO_ACK primitive in response to a DL_INFO_REQ are as follows:

Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular Service Access Point (SAP) with the stream.

CONFIGURATION

By default, the dmfe driver performs auto-negotiation to select the speed and mode of the link. Link speed and mode can be 100 Mbps (full or half-duplex) or 10 Mbps (full or half-duplex) as described in the 100Base-TX standard.

The auto-negotiation protocol automatically selects speed mode (either 100 Mbps or 10 Mbps) and operation mode (either full-duplex or half-duplex) as the highest common denominator supported by both link partners. Because the dmfe device supports all modes, this effectively selects the highest-throughput mode supported by the other device.

Alternatively, you can explicitly specify the link parameters by adding entries to the dmfe driver configuration file (/kernel/drv/dmfe.conf). You can set the speed parameter to 10 or 100 to force dmfe devices to operate at the specified speed. Additionally, you can set the full-duplex parameter to 0 or 1 to disable or force full-duplex operation, respectively.

Specifying either speed or full-duplex explicitly disables auto-negotiation. To enable the driver to determine the appropriate setting for each parameter, you should always set both parameters. If it is necessary to force either speed or duplex setting (for example, because the dmfe device is connected to an ancient device or hub that does not support auto-negotiation), both parameters should be explicitly specified to match the requirements of the external device.
