     fxp -- Intel EtherExpress PRO/100 Ethernet	device driver

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

	   device miibus
	   device fxp

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


     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.

     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

     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 val-
     ues to the	given settings.

     arp(4), miibus(4),	netintro(4), ng_ether(4), polling(4), vlan(4),

     The fxp device driver first appeared in FreeBSD 2.1.

     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.
