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