The
.Nm
driver provides support for the EtherExpress Pro/10, Pro/100B, and Pro/100+
PCI Fast Ethernet adapters based on the Intel i82557 or i82559 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

.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 .
.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" .
