CONTROLADOR ETHERNET REALTEK 10 100M PCI FAST ETHERNET DRIVER

The RealTek data sheets are of especially poor quality, and there is a lot of information missing particularly concerning the receiver operation. The driver abuses the fact that the cluster buffer pool is allocated at system startup time in a contiguous region starting at a page boundary. Set Mbps Fast Ethernet operation. The rl driver supports the following media types: The can support the same speeds and modes given an appropriate PHY chip. The differs from the in that the has an internal PHY which is controlled through special direct access registers whereas the uses an external PHY via an MII bus.

Set Mbps Fast Ethernet operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes. The controller loses all of its PCI configuration in the D3 state, so if the BIOS does not set it back to full power mode in time, it will not be able to configure it correctly.

Enable autoselection of the media type and options. The driver can check for an incomplete frame by inspecting the frame length in the header preceding the actual packet data: One particularly important fact that the data sheets fail to mention relates to the way in which the chip fills in the receive buffer.

The driver probably should not be depending on this characteristic.

For more information on configuring this device, see ifconfig 8. The rl driver supports the following media types: Versions Link to INtime 4. Note that this condition only occurs when warm booting from another operating system.

Note that the baseTX media type is only available if supported by the adapter. If the driver manages to finish processing the first frame before the chip is done DMAing the rest of the next frame, the driver may attempt to process the next frame in the buffer before the chip has had a chance to finish DMAing all of it.

The receiver uses a single fixed size ring buffer from which packets must be copied into mbufs. The receiver uses a single fixed size ring buffer from which packets must be copied into mbufs.

Furthermore, outbound packet buffers must be longword aligned or else transmission will fail. If you see this message at boot time and the driver fails to attach the device as a network interface, you will have to relatek second warm boot to have the device properly configured.

The mediaopt option can also be used to select either full-duplex or half-duplex modes.

Since cluster buffers are bytes, they are longword aligned by definition. For more information on configuring this device, see Common Network Driver Options or ifconfig.

Neither this magic value nor its significance are documented anywhere in the RealTek data sheets. For transmission, there are only four outbound packet address registers which require all outgoing packets to be stored as contiguous buffers.

Some operating systems place the controller in low power mode when shutting down, and some PCI BIOSes fail to bring the chip out of this state before configuring it. The rl driver supports the following media options: When an interrupt is posted to signal that a frame has been received, it is possible that another frame might be in the process of being copied into the receive buffer while the driver is busy handling the first one.

The supports both 10 and Mbps speeds in either full or half duplex. The supports both 10 and Mbps speeds in either full or half duplex. The rtlm driver provides support for PCI Ethernet adapters and embedded controllers based on the RealTek and Fast Ethernet controller chips. BUGS Since outbound packets must be longword aligned, the transmit routine has to copy an unaligned packet into an mbuf cluster buffer before transmission.

The can support the same speeds and modes given an appropriate PHY chip.

When the driver encounters this value, it knows that it has finished processing all currently available packets. If you power down your system prior to booting FreeBSD, the card should be configured correctly.
