In such cases, all the registers which the chip DMAs to have to be swapped and written to, so that when the hardware swaps the accesses, the chip would see them correctly. 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. It is used to translate a physical memory address into a PCI-accessible address. In which case, the driver allocates cache safe memory for its use using cacheDmaAlloc. The information listed below may be out of date. The 2 bytes of data are extracted and processed into a normal pair of bytes. However, the user may wish to force the PHY to negotiate its technology abilities a subset at a time, and according to a particular order.

This routine can use these fields in any manner. The driver programs the chip to process the transmit and receive queues at the same priority. If this routine is called with an empty but allocated string, it puts the name of this device that is, “dc” into the initStr and returns 0.

This controls how much data the device can absorb under load. On other versions of the 21×40 family, the driver reads media information from a DEC serial ROM and configures the media.

The driver supports big-endian or little-endian architectures as a configurable option. If these flags are not set then the speed is set using the SROM settings.

This should be selected taking into account the actual operating speed of the PHY. Again, see the device hardware reference manual for details.

The chip still has to be programmed to operate in little endian mode as it is on the PCI bus. A media select routine is typically defined as: On thethe driver configures the 10BASE-T interface by default,waits for two seconds, and checks the status of the link.

It is used to translate a physical memory address into a PCI-accessible address.

This routine should reset, initialize, and select lci appropriate media. 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. If the link status indicates failure, AUI interface is configured. The driver control structure member mediaCountis initialized to 0xff at startup, while the other media control members mediaDefaultmediaCurrentand gprModeVal are initialized to zero.

If the parameter is not specified, this version returns NULL. The supports HomePNA 1.

If any of the assumptions stated below are not true for your particular hardware, you need to modify the driver before it can operate correctly on your hardware. Although PCI configuration for a device is handled in the BSP, all other device programming and initialization needs are handled in this module. If there is no pre-allocated memory available pdi the driver, this parameter should be -1 NONE.

The driver also and contains error recovery code that handles known device errata related to DMA activity. This will later be used by the decGetEthernetAdr function.

If the string is allocated but not empty, this routine tries to load the device. Big-endian processors can be connected to the PCI oci through some controllers that take care of hardware byte swapping.

See below, for an explanation of each MII flag. Without modification, it can operate across the full range of architectures and targets supported by VxWorks. The user only needs to provide a valid value for this parameter if he wants to affect the order how different technology abilities are negotiated.

In such cases, all the registers which the chip DMAs to have to be swapped and written to, so that when the hardware swaps the accesses, the chip would see them correctly.

The format of the parameter string is: Alternatively, the chip can be programmed to poll for the next available transmit descriptor if the pvi engine is in idle state.

By default, the driver sets the Ethernet chip into a non-polling mode. It will retrieve the PHY’s address regardless of that, but, since the MII management interface, through which the PHY is configured, is a very slow one, providing an incorrect or invalid address may result in a particularly long boot process.

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

Transmission starts when the frame size within the transmit FIFO is larger than the treshold value. In which case, the driver allocates cache safe memory for its use using cacheDmaAlloc.
