---------------------------
What: ieee1394 core's unused exports (CONFIG_IEEE1394_EXPORT_FULL_API)
When: January 2007
Why: There are no projects known to use these exported symbols, except
dfg1394 (uses one symbol whose functionality is core-internal now).
Who: Stefan Richter <stefanr@s5r6.in-berlin.de>
---------------------------
What: ieee1394's *_oui sysfs attributes (CONFIG_IEEE1394_OUI_DB)
When: January 2007
Files: drivers/ieee1394/: oui.db, oui2c.sh
Why: big size, little value
Who: Stefan Richter <stefanr@s5r6.in-berlin.de>
---------------------------
What: Video4Linux API 1 ioctls and video_decoder.h from Video devices.
When: December 2006
Why: V4L1 AP1 was replaced by V4L2 API. during migration from 2.4 to 2.6

help
If you say Y here, then an OUI list (vendor unique ID's) will be
compiled into the ieee1394 module. This doesn't really do much
except being able to display the vendor of a hardware node. The
downside is that it adds about 300k to the size of the module,
or kernel (depending on whether you compile ieee1394 as a
module, or static in the kernel).
This option is not needed for userspace programs like gscanbus
to show this information.
