The result is that the driver will report “No EEPROM present” for the first three interfaces, and will back-fill the configuration information when the fourth interface is found. Early versions used National transcievers, but later versions are depopulated ZX boards. Since then many network adapters have used the same interface design.

The typical operating mode is matching the incoming destination address against a list of 16 addresses. The typical chip has 64 bins and uses six bits of CRC. This driver has been integrated with the kernel source tree since 1.

This is typically done by taking the CRC intermediate result just after destination address arrives, and using a few bits as the index into a table of which multicast packets are acceptable.

Please send the output from this program with any bug reports. Loading the driver module An example of loading the Tulip module is insmod tulip.

This means that in addition to the driver. The diagnostic programs are described at http: The default is usually autosense, but this may be overridden by changing the configuration EEPROM or by passing a driver option.

After reserving two entries for the broadcast and station address, that means up to 14 multicast addresses may be perfectly filtered. Many cards support multiple media types with a single MII transceiver, and must always be set to an 2140-ac type preferably 11, but other values force a specific setting.

Not all cards can have their media type set with ‘options’. Since then many network adapters have used the same interface design. When updating a single driver you will need to build pci-scan.

See also the Tulip driver development page. Scyld provides support and development servies for Linux and Beowulf clusters. Early versions used National transcievers, but later versions are depopulated ZX boards.

digitaal Options for Modules When loaded as a module the following variables may be set: Usage instructions Installation The driver installation directions are on the Driver Updates page. Tulip Multicast Support Most Ethernet chips can match a single unicast address — their own station address — and support a statistical aka hash filter for initial filtering of unwanted multicast packets.

Linux and the “Tulip” NIC Architecture

Do not bother sending email to zinc. Diagnostic program A Tulip diagnostic program is available to show the current state of the hardware, configure the EEPROM, and help debug media selection and board-setup problems.

This driver works with almost all of them: If no internal table is found, the driver configures the chip to use an MII transceiver. Announcements are also made on the driver-announce mailing list. The result is that the driver will report “No EEPROM present” for the first three interfaces, and will back-fill the configuration information when the fourth interface is found.

Using the 10base2 or Figital Port The new driver automatically switches media types attempting to find a valid selection. Donald Beckerbecker scyld.

With more than 14 multicast addresses the chip matches against a single unicast address and uses dihital statistical multicast filter with bins, resulting in much better filtering than the 64 bin chips.

Your card will only have one of these types, and you must known which type to force a setting. The list grows so rapidly that it’s impossible to keep up to date, but here are cards that I have received reports on: Most distributions based on the 21140ac. See driver source for tuning details.

You may install just one driver see below if you are using a Linux 2. Digitwl Macronix network products web page, http: The master copy of this page resides on the Scyld web server.
