     The fxp device driver supports the Intel EtherExpress 100 family of Eth-
     ernet cards based on various revisions of the i82557, i82558, i82559,
     i82559S, i82550, i82551, and i82562 chipsets.  These come in several dif-
     ferent varieties, including dual-port cards, and as built-in Ethernet so-
     lutions on certain motherboards.  This includes, among others, the fol-
     lowing 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
           Intel PRO/100 M

     This list is not exhaustive.  In particular, the fxp driver should sup-
     port any card by any manufacturer which is based on one of the aforemen-
     tioned chipsets.

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

           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

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

           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.

     Some devices are able to do interrupt coalescing but it requires firmware
     updating.  The following firmware files are potentially loaded on demand
     when an interface is brought up:


     If a file is missing, the driver attempts to operate anyway.

     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

     fxp%d: device timeout  The device has stopped responding to the network,
     or there is a problem with the network connection (cable).

     fxp%d: failed loadfirmware of file %s: errno %d  The device is able to do
     interrupt coalescing but required firmware file is missing.

     netintro(4), nsphy(4), pci(4), hostname.if(5), ifconfig(8)

     The fxp device driver first appeared in OpenBSD 2.2.

     The fxp device driver was written by David Greenman.  This manual page
     was written by David E. O'Brien.
