[dpdk-stable] patch 'common/cpt: fix encryption offset' has been queued to LTS release 18.11.10

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/25/20. 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/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/380fb4d751781f214a0055211700a88a8f730505

Thanks.

Kevin.

Subject: [PATCH] common/cpt: fix encryption offset

[ upstream commit 0058f30514f13e5d5412e97973a9c9254e36edb1 ]

In case of gmac auth the encryption offset should be set to zero.

Fixes: b74652f3a91f ("common/cpt: add microcode interface for encryption")
Fixes: 177b41ceee61 ("common/cpt: add microcode interface for decryption")
