interfaces based on the Digital Equipment Corporation

21040, 21140, 21141, 21142, and 21143 model controllers for

|
|
Generally, if the NIC is for
|
|
.Tn PCI
|
|
bus, and the major controller chip has the
|
|
.Tn DIGITAL
|
|
logo on it, with one of the model numbers above, the
|
|
.Nm
|
|
driver should recognize and control it.
|
|
Beware, however, that many NIC manufacturers change the
|
|
.Tn Ethernet
|
|
controller chip without changing the product model number, and
|
|
a physical inspection of the NIC, or a probe of the NIC with a
|
|
.Tn PCI
|
|
diagnostic tool is the only way to tell if a real
|
|
.Tn DEC
|
|
.Tn TULIP
|
|
controller is present.
|
|
.Pp
|
|
Multi-port interfaces are typically configured as a
|
|
.Tn PCI Ns \- Ns Tn PCI
|
|
bridge with multiple
|
|
.Nm
|
|
instances on the
|
|
.Tn PCI
|
|
bus on the other side of the bridge.
|
|
.Pp
|
|
.Tn DEC
|
|
sold its semiconductor division to
|
|
.Tn Intel .
|
|
In addition, there are many "knock-offs" of the
|
|
.Tn DEC
|
|
.Tn TULIP
|
|
.Tn Ethernet
|
|
controller chips; NICs based on these chips are handled by the
|
|
.Xr tlp 4
|
|
driver.
|
|
.Pp
|
|
This
|
|
.Nm
|
|
driver should not be confused with the
|
|
.Nx
|
|
.Tn VAX
|
|
.Nm
|
|
driver for the
|
|
.Tn DEC
|
|
.Tn DEUNA/DELUA
|

.Tn Ethernet
|
|
controller for
