Subject: Query about ahash support


Currently, tcrypt ahash speed test code waits for previous request to complete
before sending next crypto_ahash_update() request.
The cryptographic offload hard accelerators (e.g. CAAM) supports multiple
outstanding crypto requests for the same transform.

Does the asynchronous hash support in cryptoapi mean that one can call
crypto_ahash_update() multiple times (in pipelined fashion) without waiting
for previous crypto_ahash_update() to complete and give back the result?

Thanks & Regards
