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.
