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

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