.Sh NAME
|
|
.Nm vx
|
|
.Nd PCI Ethernet device driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device vx"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the 3Com 3c590 and 3c595 EtherLink III and Fast
|
|
EtherLink III PCI Ethernet cards in 10 Mbps mode. The medium selection
|
|
can be influenced by the following link flags to the
|
|
.Xr ifconfig 8
|
|
command:
|
|
.Pp
|
|
.Bl -tag -width LINK0X -compact
|
|
.It Em link0
|
|
Use the AUI port.
|
|
.It Em link1
|
|
Use the BNC port.
|
|
.It Em link2
|
|
Use the UTP port.
|
|
.El
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "vx%d: not configured; kernel is built for only %d devices."
|
|
There are not enough devices in the kernel configuration file for the number
|
|
of adapters present in the system. Add devices to the configuration file,
|
|
rebuild the kernel, and reboot.
|
|
.El
|
|
.Pp
|
|
All other diagnostics indicate either a hardware problem or a bug in the
|
|
driver.
|
|
.Sh CAVEATS
|
|
Some early-revision 3c590 cards are defective and suffer from many receive
|
|
overruns, which cause lost packets. The author has attempted to implement
|
|
a test for it based on the information supplied by 3Com, but the test resulted
|
|
mostly in spurious warnings.
|
|
.Pp
|
|
The performance of this driver is somewhat limited by the fact that it uses
|
|
only polled-mode I/O and does not make use of the bus-mastering capability
|
|
of the cards.
|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
driver is known not to reset the adapter correctly following a warm boot
|
|
on some systems.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver has not been exhaustively tested with all the models of cards that it
|
|
claims to support.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver first appeared in
|
|
.Fx 2.1 .
|
|
It was derived from the
|
|
.Nm ep
|
|
driver, from which it inherits most of its limitations.
