.Sh NAME
|
|
.Nm fwe
|
|
.Nd "Ethernet emulation driver for FireWire"
|
|
.Sh SYNOPSIS
|
|
To compile support for the
|
|
.Nm
|
|
driver into your kernel, place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device firewire"
|
|
.Cd "device fwe"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the
|
|
.Nm
|
|
driver at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_fwe_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides non-standard Ethernet emulation over FireWire (IEEE 1394).
|
|
.Pp
|
|
.Xr firewire 4
|
|
and
|
|
.Xr fwohci 4
|
|
must be configured in the kernel as well.
|
|
.Pp
|
|
This driver exploits asynchronous stream over IEEE 1394 to carry Ethernet
|
|
frames.
|
|
The stream channel can be specified by
|
|
the
|
|
.Va hw.firewire.fwe.stream_ch
|
|
.Xr sysctl 8 .
|
|
.Pp
|
|
This driver supports
|
|
.Xr polling 4
|
|
as well if it is compiled with the
|
|
.Dv DEVICE_POLLING
|
|
option.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver first appeared in
|
|
.Fx 5.0 .
|
|
.Sh AUTHORS
|
|
The
|
|
.Nm
|
|
driver and this manual page were written by
|
|
.An Hidetoshi Shimokawa .
|
|
.Sh 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).
