FXP(4)                 FreeBSD Kernel Interfaces Manual                 FXP(4)

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.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 fur-
     ther 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:

     +o   Intel EtherExpress PRO/10
     +o   Intel InBusiness 10/100
     +o   Intel PRO/100B / EtherExpressPRO/100 B PCI Adapter
     +o   Intel PRO/100+ Management Adapter
     +o   Intel PRO/100 VE Desktop Adapter
     +o   Intel PRO/100 M Desktop Adapter
     +o   Intel PRO/100 S Desktop, Server and Dual-Port Server Adapters
     +o   Contec C-NET(PI)-100TX (PC-98)
     +o   NEC PC-9821Ra20, Rv20, Xv13, Xv20 internal 100Base-TX (PC-98)
     +o   NEC PC-9821X-B06 (PC-98)
     +o   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 val-
     ues to the given settings.

HISTORY
     The fxp device driver first appeared in FreeBSD 2.1.

AUTHORS
     The fxp device driver was written by David Greenman.  It has then been
     updated to use the busdma API and made endian-clean by Maxime Henrion.
     This manual page was written by David E. O'Brien.
