[dpdk-stable] patch 'crypto/qat: fix digest in buffer' has been queued to stable release 20.11.1

Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/2b0467f2a39588ed78a27a05ba2f2ba136936f80

Thanks.

Luca Boccassi

Subject: [PATCH] crypto/qat: fix digest in buffer

[ upstream commit 7a13a3939dc82819e47bb89384dcad469ed7a61c ]

This patch fixes the missed digest in buffer support to
QAT symmetric raw API. Originally digest in buffer is
supported only for wireless algorithms

Fixes: 728c76b0e50f ("crypto/qat: support raw datapath API")
