de - "DEC DC21x4x Ethernet device driver"
To compile support for the de driver into your kernel, place the following line in your kernel configuration file:
.Cd "device de"
Alternatively, to load the de driver at boot time, place the following line in loader.conf(5):
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 an 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, DE425, 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 devices 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. |
Since the 21040 is available on both EISA and PCI boards, one must be careful in how one defines the 21040 in the kernel config file.
