I think it's more fundamental than that.  If ralink -- or anyone else --
submitted a plagiarized driver to the staging tree, we should remove it
immediately unless the copyright holder (David in this case) is willing
to allow us to retain it while things are sorted out.

And yes, David still needs to contact ralink about sorting out the
violation.

Finally, obviously, a proper Linux driver should use the AES facilities
in the kernel crypto core.
