de -- DECchip 21040, 21140, 21141, 21142, and 21143 PCI Ethernet inter-
de* at pci? dev ? function ?
Configuration of PHYs may also be necessary. See mii(4).
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.
