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. SEE ALSO

de -- DEC DC21x4x Ethernet device driver SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file: device de Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_de_load="YES" DESCRIPTION
The de driver provides support for the Ethernet adapters based on the Digital Equipment DC21x4x based self-contained Ethernet and Fast Ether- net chips. The de driver supports the following media types: autoselect Enable autoselection of the media type and options 10baseT/UTP Set 10Mbps operation on the 10baseT port 10base2/BNC Set 10Mbps operation on the BNC port 10base5/AUI Set 10Mbps operation on the AUI port 100baseTX Set 100Mbps (Fast Ethernet) operation 100baseFX Set 100Mbps operation 100baseT4 Set 100Mbps operation (4-pair cat-3 cable) The de driver supports the following media options: full-duplex Set full duplex operation Note that the media types available depend on the particular card in use. Some cards are explicitly programmed to a particular media type by a setup utility and are not changeable. Use the ifconfig(8) command and in particular the -m flag to list the supported media types for your particular card. The old ``ifconfig linkN'' method of configuration is not supported. HARDWARE
Adapters supported by the de driver include: o Adaptec ANA-6944/TX o Cogent EM100FX and EM440TX o Corega FastEther PCI-TX o D-Link DFE-500TX o DEC DE435, DEC DE450, and DEC DE500 o ELECOM LD-PCI2T, LD-PCITS o I-O DATA LA2/T-PCI o SMC Etherpower 8432, 9332 and 9334 o ZNYX ZX3xx DIAGNOSTICS
de%d: waking device from sleep/snooze mode The 21041 and 21140A chips support suspending the operation of the card. de%d: error: desired IRQ of %d does not match device's actual IRQ of %d The device probe detected that the board is configured for a differ- ent interrupt than the one specified in the kernel configuration file. de%d: not configured; limit of %d reached or exceeded There is a limit of 32 de devices allowed in a single machine. de%d: not configured; 21040 pass 2.0 required (%d.%d found) de%d: not configured; 21140 pass 1.1 required (%d.%d found) Certain revisions of the chipset are not supported by this driver.
