Summary

Add a new COP_F_CIPHER_FIRST flag for struct crypt_op.

This requests that the cipher be performed before rather than after
the HMAC when both are specified for a single operation.

Test Plan
  • testing IPSec-like encrypt-then-authenticate operations from userland via the cryptocheck tool on ccr0 and cryptosoft
  • encryption operations need this flag for EtA while decryption operations do not
