| 4 | Subject: [PATCH] cryptodev: add symmetric crypto data-path APIs |
| 5 | |
| 6 | This patch adds data-path APIs for enqueue and dequeue operations to |
| 7 | cryptodev. The APIs support flexible user-define enqueue and dequeue |
| 8 | behaviors and operation modes. The QAT PMD is also updated to |
| 9 | support this feature. |
