   4 Subject: [PATCH] crypto: caam/qi2 - add OPR (Order Preservation) support
   5 MIME-Version: 1.0
   6 Content-Type: text/plain; charset=UTF-8
   7 Content-Transfer-Encoding: 8bit
   8
   9 During driver upstreaming OPR was removed due to lacking users.
  10 Add OPR back, since in LSDK / LSDK-based ADKs there is at least
  11 one user (ASF / VortiQa IPsec).
