The
de driver supports Ethernet and Fast Ethernet interfaces based on the Digital Equipment Corporation DECchip 21040, 21140, 21141, 21142, and 21143 model controllers for PCI bus.
21040
10BASE-T and AUI/BNC
21140
10BASE-T and 100BASE-TX
21141
10BASE-T and 100BASE-TX
21142
10BASE-T and 100BASE-TX
21143
10BASE-T and 100BASE-TX
Supported Network Interface Cards (NIC) include, but are not limited to:
Znyx NetBlaster ZX340 series (345, 348, 346)
Generally, if the NIC is for PCI bus, and the major controller chip has the DIGITAL logo on it, with one of the model numbers above, the
de driver should recognize and control it. Beware, however, that many NIC manufacturers change the Ethernet controller chip without changing the product model number, and a physical inspection of the NIC, or a probe of the NIC with a PCI diagnostic tool is the only way to tell if a real DEC TULIP controller is present.
Multi-port interfaces are typically configured as a PCI-PCI bridge with multiple
de instances on the PCI bus on the other side of the bridge.
DEC sold its semiconductor division to Intel. In addition, there are many "knock-offs" of the DEC TULIP Ethernet controller chips; NICs based on these chips are handled by the
tlp(4) driver.
This
de driver should not be confused with the
NetBSD VAX
de driver for the DEC DEUNA/DELUA Ethernet controller for UniBus.
