fxp -- Intel EtherExpress Pro/100B ethernet device driver
device miibus
device fxp
The fxp driver provides support for the EtherExpress Pro/10, InBusiness
10/100, Pro/100 B, Pro/100+, Pro/100 VE, Pro/100 M, and Pro/100 S PCI
Fast Ethernet adapters based on the Intel i82557, i82558, i82559, i82550,
or i82562 Ethernet chips. Many on-board network interfaces on Intel
motherboards use these chips and are also supported.
The fxp driver supports the following media types:
autoselect Enable autoselection of the media type and options
10baseT/UTP Set 10Mbps operation
100baseTX Set 100Mbps (fast ethernet) operation
The fxp driver supports the following media options:
full-duplex Set full duplex operation
Note that 100baseTX media type is not available on the Pro/10. For further
information on configuring this device, see ifconfig(8).
The fxp driver also supports a special link option:
link0 Some chip revisions have loadable microcode which can be used to
reduce the interrupt load on the host cpu. Not all boards have
microcode support. Setting the link0 flag with ifconfig(8) will
download the microcode to the chip if it is available.
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 mbuf's 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: Ethernet address ff:ff:ff:ff:ff:ff In some Alpha's (AXPpci and
Multia) you must tell the driver to use (slower) I/O rather than memory
to access the card. Create, if it does not yet exist, and add to the
file /boot/device.hints the line ``hint.fxp.0.prefer_iomap="0"''.
fxp%d: Microcode loaded, int_delay: %d usec bundle_max: %d The chip has
successfully downloaded the microcode, and changed the parameterized values
to the given settings.
arp(4), miibus(4), netintro(4), ng_ether(4), ifconfig(8)
The fxp device driver first appeared in FreeBSD 2.1.
The fxp device driver was written by David Greenman. It has then been
updated to use the busdma API and made endian-clean by Maxime Henrion.
