It's not even the primary driver.  Is there anything that this driver
provides that isn't provided by the upstream supported, mainline
rt2x00 project?  I.e., can we just delete the staging driver?

If we are going to keep the staging driver for some reason, one of the
things that should be added to the TODO list would be delete its
driver-specific AES code and replace it with calls to the kernel's
generic AES code, which among other things, has the advantage that it
can take advantage of the AES-NI instructions provided on more modern
x86 CPU's.

David, you might want to contact ralink directly, since it's likely
they are distributing that driver with your AES code in other places
besides just in the mainstream kernel sources.  Even if we delete the
code in the staging tree, they might be distributing that driver still
via other means.
