[dpdk-stable] patch 'crypto/octeontx2: fix unaligned access to device memory' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/e4509540bed8f2a21e17fe47ee90214db00ffecd

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 05f157b8c5b469173712b0ab7daa91bbe52ec1df ]

Use otx2_mbox_memcpy() instead of memcpy() to prevent unaligned access.
