I'm having a bad day,  AES was always in there,  just recently RC4 and
AES192 were added.

Have a look at the mail list archives,  several before you have got this
working on the geode, it's just a matter of getting it all together
correctly.  If you can't find anything then send in:

	* output of lsmod (if you are running as modules)
	* output of "cryptotest -a aes" with cryptodev loaded and without
	  cryptodev loaded.
	* output of "openssl speed -evp aes -elapsed" with cryptodev loaded
	  and without.

Note that openssl uses cryptodev by default if it detects it.

Cheers,
