NAME

fwe -- Ethernet emulation driver for FireWire

SYNOPSIS

kldload firewire kldload if_fwe or device fwe device firewire device fwohci

DESCRIPTION

The fwe driver provides non-standard ethernet emulation over FireWire (IEEE 1394). firewire(4) and fwohci(4) must be configured in the kernel as well. This driver exploits asynchronous stream over IEEE 1394 to carry Ethernet frames. The stream channel can be specified by the hw.firewire.fwe.stream_ch sysctl(8). For more information on configuring this device, see ifconfig(8). The fwe driver supports polling(4).

HISTORY

The fwe device driver first appeared in FreeBSD 5.0.

The fwe driver and this manual page were written by Hidetoshi Shimokawa.

BUGS

This driver emulates ethernet in a very adhoc way and it does not reserve a stream channel using an isochronous manager. Note that this driver uses a protocol which is very different from RFC 2734 (IPv4 over IEEE 1394). DragonFly 3.7 November 8, 2002 DragonFly 3.7
