[v2,4/7] cryptodev: add hash algorithms in asymmetric capability
Checks
Commit Message
Most of the asymmetric operations start with hash of the input.
But a PMD might also support only plain input (eg openssl).
Add a new field in asymmetric capability to declare support
for hash operations that PMD can support for the asymmetric
operations. Application can skip computing hash if PMD already
supports it.
