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

SYNOPSIS
     device miibus
     device fxp

DESCRIPTION
     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  mother-
     boards 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 re-
	    duce  the  interrupt load on the host cpu.	Not all boards have sup-
	    port microcode support.  Setting the  link0  flag  with  ifconfig(8)
	    will download the microcode to the chip if it is available.

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 Mul-
     tia) you must tell the driver to use (slower) I/O rather than memory to ac-
     cess 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.
