NAME
de —
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
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:
- 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.
