NAME

fxp - Intel EtherExpress PRO/100 Ethernet device driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:
device miibus device fxp

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

 if_fxp_load="YES"
 

DESCRIPTION

The driver provides support for Ethernet adapters based on the Intel i82557, i82558, i82559, i82550, and i82562 chips.

The driver supports the following media types:

autoselect
Enable autoselection of the media type and options
10baseT/UTP
Set 10Mbps operation
100baseTX
Set 100Mbps (Fast Ethernet) operation

The driver supports the following media options:

full-duplex
Set full duplex operation

Note that 100baseTX media type is not available on the Pro/10. For further information on configuring this device, see ifconfig(8).

The driver supports reception and transmission of extended frames for vlan(4). This capability of can be controlled by means of the vlanmtu parameter to ifconfig(8).

The driver also supports a special link option:

link0
Some chip revisions have loadable microcode which can be used to reduce the interrupt load on the host cpu. Not all boards have microcode support. Setting the link0 flag with ifconfig(8) will download the microcode to the chip if it is available.

HARDWARE

Adapters supported by the driver include:

DIAGNOSTICS

"fxp%d: couldn't map memory"
A fatal initialization error has occurred.
"fxp%d: couldn't map interrupt"
A fatal initialization error has occurred.
"fxp%d: Failed to malloc memory"
There are not enough mbuf's available for allocation.
"fxp%d: device timeout"
The device has stopped responding to the network, or there is a problem with the network connection (cable).
"fxp%d: Microcode loaded, int_delay: %d usec bundle_max: %d"
The chip has successfully downloaded the microcode, and changed the parameterized values to the given settings.
