NAME
     fxp - Intel EtherExpress PRO/100 Ethernet driver

SYNOPSIS
     fxp* at pci? dev ? function ?
     fxp* at cardbus? dev ? function ?

DESCRIPTION
     The fxp device driver supports the Intel EtherExpress 100 family of Eth-
     ernet cards based on the i82557, i82558, and i82559 chipsets.  These come
     in several different varieties, including dual-port cards, and as built-
     in Ethernet solutions on certain motherboards.  This includes, among oth-
     ers, the following models:

           Intel EtherExpress PRO/100 PCI
           Intel EtherExpress PRO/100B PCI
           Intel EtherExpress PRO/100+ PCI
           Intel EtherExpress PRO/100 Dual-Port PCI
           Intel PRO/100 CardBus II PC Card
           Intel PRO/100 VE
           Intel PRO/100 VM

     Other models of Intel network cards are supported by the ie(4) and iy(4)
     drivers.  This list is not exhaustive.  In particular, the fxp driver
     should support any card by any manufacturer which is based on one of the
     aforementioned chipsets.

     The following media types and options (as given to ifconfig(8)) are sup-
     ported:

           media autoselect
                Enable autoselection of the media type and options (default).

           media 100baseTX mediaopt full-duplex
                Set 100Mbps (Fast Ethernet) operation and force full-duplex
                mode.

           media 100baseTX mediaopt half-duplex
                Set 100Mbps (Fast Ethernet) operation and force half-duplex
                mode.

           media 10baseT mediaopt full-duplex
                Set 10Mbps operation and force full-duplex.

           media 10baseT mediaopt half-duplex
                Set 10Mbps operation and force half-duplex.

     If no media options are present, the fxp driver places the card into au-
     toselect mode.

     These cards also come with a variety of PHYs.  Models exist with PHYs
     supported by both the inphy(4) and nsphy(4) drivers.

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 mbufs 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).
