crypto: testmgr - Add testing for async hashing and update/final
Extend testmgr such that it tests async hash algorithms, and that for both sync and async hashes it tests both ->digest() and ->update()/->final() sequences. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
