| 4 | Subject: [dpdk-dev] crypto/qat: fix failed raw data path dequeue |
| 5 | |
| 6 | This patch fixes the raw data path dequeue burst fail problem. |
| 7 | Previously the in case the queue is full and not all packets |
| 8 | asked to be dequeued are processed, the dequeue burst will |
| 9 | never happen. |
| 10 | |
| 11 | Fixes: c21574edc52a ("cryptodev: add dequeue count parameter in raw API") |
