7. DEC Driver — RTEMS Networking User Manual (master) documentation

Driver basic operation 5. To achieve this, the driver requires a few external support routines as well as several target-specific parameters.

DEC Driver Introduction 7. Currently, this tool does not support the DEC board.

The driver uses this value to program register CSR6. This thread is event driven. Understand the network scheduling conventions 3.

dec21x40End

See below, for an explanation of each MII flag. All of the device-specific parameters are passed in the initStr.

The information listed below may be out of date. A media select routine is typically defined as: These parameters, and the mechanisms used to communicate them to the driver, are detailed below. On other versions of the 21x40 family, the driver reads media information from a DEC serial ROM and configures the media. The 21140x should be specified as hexadecimal strings optionally preceded by "0x" or a minus sign "-". First draft of this document Planned releases: This routine can use these fields in any manner.

Then the driver connects an interrupt handler to the interrupt line driven by the Ethernet controller the only interrupt which will be treated is the receive interrupt and launches 2 threads: Without modification, it can operate across the full range of architectures and targets supported by VxWorks. Testing the Driver 5. 2140a starts when the frame size within the transmit FIFO is larger than the treshold value.

Adding a Default Route 4.

Command and Variable Index Index. If the string is allocated but not empty, this routine tries to load the device. If the cpu board hardware automatically swaps all the accesses to and from the PCI bus, then input and output byte stream need not be swapped. Write the Driver Start Function. Application Programming Interface 4. Alternatively, the chip can be programmed to poll for the next available transmit descriptor if the transmit engine is in idle state.

Software and Drivers for the Intel® PRO/ Adapter

If this routine is called with an empty but allocated string, it puts the name eec this device that is, "dc" into the initStr and returns 0. This should be selected taking into account the actual operating speed of the PHY.

Big-endian processors can be connected to the PCI bus through some controllers that take care of hardware byte swapping. Network Driver Makefile 3. Once the attach function executed, the driver initializes the DEC chip. Including the required managers 4. Network device configuration 4. 2140a about the network device 3.
