NAME    [Toc]    [Back]

     fxp -- Intel EtherExpress Pro/100B ethernet device driver

SYNOPSIS    [Toc]    [Back]

     device miibus
     device fxp

DESCRIPTION    [Toc]    [Back]

     The fxp driver provides support for the EtherExpress Pro/10, InBusiness
     10/100, Pro/100 B, Pro/100+, Pro/100 VE, Pro/100 M, and Pro/100 S PCI
     Fast Ethernet adapters based on the Intel i82557, i82558, i82559, i82550,
     or i82562 Ethernet chips.	Many on-board network interfaces on Intel
     motherboards use these chips and are also supported.

     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 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.

DIAGNOSTICS    [Toc]    [Back]

     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

     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.

HISTORY    [Toc]    [Back]

     The fxp device driver first appeared in FreeBSD 2.1.

AUTHORS    [Toc]    [Back]

     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.
