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.
