    help

      Enable openssl cryptodev (OCF) hardware acceleration support.

      This requires the ocf linux kernel extension or you to provide a

      pre-patched kernel that includes it.

      If kernel support isn't available it'll just make the libraries

      a tiny bit larger with a small CPU overhead when starting up and

      checking for the required kernel-side support, and then falling

      back to regular builtin support.
