From: Pablo de Lara Date: Wed, 19 Jul 2017 04:59:02 +0000 (+0100) Subject: crypto/qat: fix session initialization X-Git-Tag: spdx-start~2387 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b264a1ab0627614a17005cde39152b749d0a01c3;p=dpdk.git crypto/qat: fix session initialization When creating a session, if there is a failure when setting some of the parameters, QAT was not propagating the error to the session initialization function. Therefore, it was reporting a success, when it should be report a failure.
