How about making the buffer size configurable during probe time via module

Why do you even need to support this? What's the use-case?

Openssl uses init->update->final sequencing, and it would be nice to have this use crypto accelerator. Otherwise we basically support cipher acceleration from openssl, but not hashing.

FWIW IPsec only uses digest.

IPSec only uses digest yes, this is not an issue.
