.Sh NAME
|
|
.Nm fxp
|
|
.Nd Intel EtherExpress Pro/100B ethernet device driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device miibus"
|
|
.Cd "device fxp"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the EtherExpress Pro/10, Pro/100B, and Pro/100+
|
|
PCI Fast Ethernet adapters based on the Intel i82557, i82558, i82559
|
|
or i82550 ethernet chips.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It autoselect
|
|
Enable autoselection of the media type and options
|
|
.It 10baseT/UTP
|
|
Set 10Mbps operation
|
|
.It 100baseTX
|
|
Set 100Mbps (fast ethernet) operation
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It full-duplex
|
|
Set full duplex operation
|
|
.El
|
|
.Pp
|
|
Note that 100baseTX media type is only available on the Pro/100B and Pro/100+.
|
|
For further information on configuring this device, see
|
|
.Xr ifconfig 8 .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver also supports a special link option:
|
|
.Bl -tag -width link0
|
|
.It Cm link0
|
|
Some chip revisions have loadable microcode which can be used to reduce the
|
|
interrupt load on the host cpu.
|
|
Not all boards have support microcode support.
|
|
Setting the
|
|
.Cm link0
|
|
flag with
|
|
.Xr ifconfig 8
|
|
will download the microcode to the chip if it is available.
|
|
.El
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "fxp%d: couldn't map memory"
|
|
A fatal initialization error has occurred.
|
|
.It "fxp%d: couldn't map interrupt"
|
|
A fatal initialization error has occurred.
|
|
.It "fxp%d: Failed to malloc memory"
|
|
There are not enough mbuf's available for allocation.
|
|
.It "fxp%d: device timeout"
|
|
The device has stopped responding to the network, or there is a problem with
|
|
the network connection (cable).
|
|
.It "fxp%d: Ethernet address ff:ff:ff:ff:ff:ff"
|
|
In some Alpha's (AXPpci and Multia) you must tell the driver to use (slower)
|
|
I/O rather than memory to access the card.
|
|
Create, if it does not yet exist, and add to the file
|
|
.Pa /boot/device.hints
|
|
the line
|
|
.Dq Li hint.fxp.0.prefer_iomap="0" .
|
|
.It "fxp%d: Microcode loaded, int_delay: %d usec bundle_max: %d"
|
|
The chip has successfully downloaded the microcode, and changed the
|
|
parametrized values to the given settings.
