Good. You can still do precisely that, and build the firmware into your
kernel. You can have exactly what you like. Hey, you can build even
_more_ firmware into your kernel now. You can have NFS-root on devices
you previously had to use an initrd for. hth.

In all the years we've been using request_firmware(), nobody ever asked
for a way to build the firmware _into_ the .ko file, until now. Why is
it suddenly so important for a small handful of older network drivers,
when nobody else has ever seen the need for it -- even in modern network
drivers?
