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
accept being able to display the vendor of a hardware node. The
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).
