Subject: crypto/qat: fix raw data path dequeue
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fe9e06ab0887b442eecc32caa51134b9ac442325;p=dpdk.git

crypto/qat: fix raw data path dequeue

This patch fixes the raw data path dequeue burst fail problem.
Previously 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")
