fwe(4)

NAME

fwe - Ethernet emulation driver for FireWire

SYNOPSIS

To compile this driver into the kernel, place the  following
lines in your
kernel configuration file:
      device firewire
      device fwe
Alternatively,  to load the driver as a module at boot time,
place the
following line in loader.conf(5):
      if_fwe_load="YES"

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).

This driver supports polling(4) as well if it is compiled

with the
DEVICE_POLLING option.

HISTORY

The fwe device driver first appeared in FreeBSD 5.0.

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).
