So it sounds like it's working but ocf-bench is causing the driver
headaches.

Which version of ocf are you using ?

Check through the ocf-bench code for something like this:

	if (request_batch)
		crp->crp_flags |= CRYPTO_F_BATCH;
	if (request_cbimm)
		crp->crp_flags |= CRYPTO_F_CBIMM;

If you have it then good,  otherwise you need to find where crp->crp_flags
is set and try setting it to one of the following:

		crp->crp_flags = (CRYPTO_F_BATCH|CRYPTO_F_CBIMM);
		crp->crp_flags = CRYPTO_F_CBIMM;
		crp->crp_flags = CRYPTO_F_BATCH;
		crp->crp_flags = 0;

That may fix it. Also,  the latest ocf-bench does an SHA1/AES test,  just in
case that is confusing you with des working above.  So not only does it use
AES but it also hashes at the same time.  Could be something to look into.

Cheers,
