.Nd Ethernet emulation driver for FireWire
|
|
.Sh SYNOPSIS

.Cd "kldload firewire"
|

.Cd "kldload if_fwe"
|

|
|
.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 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).
