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.
SEE ALSO¶
arp(4), firewire(4), fwip(4), fwohci(4), netintro(4), ng_ether(4), polling(4), ifconfig(8), kldload(8), sysctl(8)
HISTORY¶
The fwe
device driver first appeared in
FreeBSD 5.0.
AUTHORS¶
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).
