Subject: [dpdk-dev] [PATCH v2] compress/qat: fix return correct status on qat overflow
Date: Thu, 27 Dec 2018 11:42:19 +0100	[thread overview]
Message-ID: <1545907339-16639-2-git-send-email-tomaszx.jozwiak@intel.com> (raw)
In-Reply-To: <1545907339-16639-1-git-send-email-tomaszx.jozwiak@intel.com>

This patch fixes correct status in case of overflow on
QAT is detected.
In that case RTE_COMP_OP_STATUS_OUT_OF_SPACE_TERMINATED value is set in
rte_comp_op.status field instead of RTE_COMP_OP_STATUS_ERROR

Fixes: 32842f2a6d7d ("compress/qat: create FW request and process response")
Cc: stable@dpdk.org
