+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")
