DECchip 21040, 21140, 21141, 21142, and
21143 PCI Ethernet interface driver
SYNOPSIS
de* at pci? dev ? function ?
Configuration of PHYs may also be necessary. See mii(4).
DESCRIPTION
Thede 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:
- Accton EN1207i
- Cogent EM100
- Asante AsanteFAST
- DEC DE435
- DEC DE450
- DEC DE500
- SMC 9332
- 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.
