[v4,5/7] cryptodev: add RNG capability in EC based xform
Checks
Commit Message
Elliptic curve based asymmetric operations use cryptographically
secure random number in its computation. If PMD supports RNG
for such ops, the application could skip computing on its own.
This patch adds new field in asymmetric capability to declare
this capability.
