DESCRIPTION

     The fxp device driver supports the Intel EtherExpress 100 family of
     Ethernet cards based on various revisions of the i82557, i82558, i82559,
     i82559S, i82550, i82551, and i82562 chipsets, including the following:

           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
           Intel PRO/100 S

     The following media types and options (as given to ifconfig(8)) are
     supported:

           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
     autoselect mode.


FILES

     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:

           /etc/firmware/fxp-d101a
           /etc/firmware/fxp-d101b0
           /etc/firmware/fxp-d101ma
           /etc/firmware/fxp-d101s
           /etc/firmware/fxp-d102
           /etc/firmware/fxp-d102c
           /etc/firmware/fxp-d102e

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


DIAGNOSTICS

     fxp0: couldn't map memory  A fatal initialization error has occurred.

     fxp0: couldn't map interrupt  A fatal initialization error has occurred.

     fxp0: Failed to malloc memory  There are not enough mbufs available for
     allocation.

     fxp0: device timeout  The device has stopped responding to the network,
     or there is a problem with the network connection (cable).

     fxp0: error N, could not read firmware ...  The device is able to do
     interrupt coalescing but required firmware file is missing.
