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. These come in several different varieties, including dual-port cards, and as built-in Ethernet solutions on certain motherboards. This includes, among others, 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
Intel PRO/100 M
Intel PRO/100 S

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 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

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).

fxp%d: error %d, could not read firmware %s The device is able to do interrupt coalescing but required firmware file is missing.
