.Dd November 8, 2002 .Dt FWE 4 .Os .Sh NAME .Nm fwe .Nd Ethernet Emulation Driver for FireWire .Sh SYNOPSIS .Cd "device fwe" .Cd "device firewire" .Cd "device fwohci" .Sh DESCRIPTION The .Nm driver provides non-standard ethernet emulation over FireWire(IEEE1394).
p .Nm firewire and .Nm fwohci must be configured in the kernel as well.
p This driver exploits asynchronous stream over IEEE1394 to carry Ethernet frames. The stream channel can be specified by .Nm sysctl(8) (hw.firewire.fwe.stream_ch).
p This driver supports polling(4) as well if it's compiled with DEVICE_POLLING option. .Sh HISTORY The fwe device driver first appeared in FreeBSD 5.0. .Sh BUGS This driver emulates ethernet very adhoc way and it doesn't reserve a stream channel using an isochronous manager. Note this driver uses very different protocol from RFC2734(IPv4 over IEEE 1394). .Sh SEE ALSO .Xr arp 4 , .Xr firewire 4 , .Xr fwohci 4 , .Xr netintro 4 , .Xr ng_ether 4 , .Xr polling 4 , .Xr ifconfig 8 , .Xr sysctl 8 .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Hidetoshi Shimokawa .
