0c53decdd0 firewire: new stack is no longer experimental
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.

b9530fd6c3 firewire: net: add Kconfig item, rename driver
The driver is now called firewire-net.  It might implement the transport
of other networking protocols in the future, notably IPv6 per RFC 3146.

ad3c0fe8b8 firewire: debug interrupt events
This adds debug printks for asynchronous transmission and reception and
for self ID reception.  They can be enabled at module load time, and at
runtime via /sys/module/firewire_ohci/parameters/debug.

Signed-off-by: Jarod Wilson <jwilson@redhat.com>

Also added:  Logging of interrupt event codes and of cancelled AT
packets.

The code now depends on a Kconfig variable.  This makes it easier to
build firewire-ohci without the feature or to make it an option in the
future.  The variable is currently hidden and always on.

This feature inflates firewire-ohci.ko by 7 kB = 27% on x86-64 and by
4 kB = 23% on i686.

fe77d4f283 firewire: add Kconfig help on building both stacks
Alas that won't work so good, because nobody reads help texts.

I thought about adding some crude multiple choice selection (build the
old stack, build the new stack, build both stacks).  It's possible, but
it would introduce awkward dummy config variables.

9a60731d00 firewire: prefix modules with firewire- instead of fw-
Of course everybody immediately associates "fw-" with FireWire, not
firmware or firewall or whatever.  But "firewire-" has a nice ring to
it too.
