firewire: new stack is no longer experimental

Browse source 
The new stack is now recommended over the old one if used for industrial
video (IIDC/DCAM) or for storage devices (SBP-2) due to better
performance, improved compatibility, added features, and security.  It
should also be functionally on par with and is more secure than the old
ieee1394 stack in the use case of consumer video devices.

IP-over-1394 support for the new stack is currently emerging, and a
backend of the firedtv DVB driver to the new stack should be available
soon.

The one remaining area where the old stack is still required are audio
devices, as the new stack is not yet able to support the FFADO FireWire
audio framework.

This is the "Juju" FireWire stack, a new alternative implementation
designed for robustness and simplicity. You can build either this
stack, or the old stack (the ieee1394 driver, ohci1394 etc.) or both.
Please read http://ieee1394.wiki.kernel.org/index.php/Juju_Migration
before you enable the new stack.
This is the new-generation IEEE 1394 (FireWire) driver stack
a.k.a. Juju, a new implementation designed for robustness and
simplicity.
See http://ieee1394.wiki.kernel.org/index.php/Juju_Migration
for information about migration from the older Linux 1394 stack
to the new driver stack.
To compile this driver as a module, say M here: the module will be
called firewire-core.
This module functionally replaces ieee1394, raw1394, and video1394.
To access it from application programs, you generally need at least
libraw1394 version 2. IIDC/DCAM applications also need libdc1394
version 2. No libraries are required to access storage devices
through the firewire-sbp2 driver.
libraw1394 v2. IIDC/DCAM applications need libdc1394 v2.
No libraries are required to access storage devices through the
firewire-sbp2 driver.
NOTE:
FireWire audio devices currently require the old drivers (ieee1394,
ohci1394, raw1394).

This enables IPv4 over IEEE 1394, providing IP connectivity with
other implementations of RFC 2734 as found on several operating
systems. Multicast support is currently limited.
NOTE, this driver is not stable yet!
To compile this driver as a module, say M here: The module will be
called firewire-net. It replaces eth1394 of the classic IEEE 1394
