SYNOPSIS

To compile support for the fxp driver into your kernel, place the following lines in your kernel configuration file:


.Cd "device miibus"


.Cd "device fxp"

Alternatively, to load the fxp driver at boot time, place the following line in loader.conf(5):
if_fxp_load="YES"

DESCRIPTION

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

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

The fxp 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 fxp driver include:

  • Intel EtherExpress PRO/10
  • Intel InBusiness 10/100
  • Intel PRO/100B / EtherExpressPRO/100 B PCI Adapter
  • Intel PRO/100+ Management Adapter
  • Intel PRO/100 VE Desktop Adapter
  • Intel PRO/100 M Desktop Adapter
  • Intel PRO/100 S Desktop, Server and Dual-Port Server Adapters
  • Contec C-NET(PI)-100TX (PC-98)
  • NEC PC-9821Ra20, Rv20, Xv13, Xv20 internal 100Base-TX (PC-98)
  • NEC PC-9821X-B06 (PC-98)
  • Many on-board network interfaces on Intel motherboards

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: 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 /boot/device.hints the line "hint.fxp.0.prefer_iomap= "0"".
"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.
