de — DEC DC21x4x Ethernet device driver
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"
The de driver is not present in FreeBSD 13.0 and later. See https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more information.
The de driver provides support for the Ethernet adapters based on the Digital Equipment DC21x4x based self-contained Ethernet and Fast Ethernet 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.
Adapters supported by the de driver include: • Adaptec ANA-6944/TX • Cogent EM100FX and EM440TX • Corega FastEther PCI-TX • D-Link DFE-500TX • DEC DE435, DEC DE450, and DEC DE500 • ELECOM LD-PCI2T, LD-PCITS • I-O DATA LA2/T-PCI • SMC Etherpower 8432, 9332 and 9334 • ZNYX ZX3xx
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 different 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.
