You're right. We'll need to do this in a backwards-compatible way. In fact
we already do something similar in skcipher.c itself. Simply look at the
cra_type field and if it matches blkcipher/ablkcipher/givcipher then it's
legacy ablkcipher, otherwise it's skcipher.

Also the way crypto_engine looks at the request type in the data-path is
suboptimal. This should really be built into the cra_type object. For
example, we can have cra_type->engine->prepare_request which would just
do the right thing.

Thanks,
