patch 'eventdev/crypto: fix offset used while flushing events' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/01/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=e1ca28205f1b781a12ec52c49fbd5c63ab07db2b

Thanks.

Subject: [PATCH] eventdev/crypto: fix offset used while flushing events
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit da73a2a0d10f270acf3bb9c90f79545d27e8f562 ]

Events enqueued to eventdev from the beginning of the circular buffer.
This leads to invalid or already freed events getting enqueued to eventdev
from the circular buffer.

Fixed by enqueuing the events to eventdev from the head pointer of
circular buffer.

Fixes: 7901eac3409a ("eventdev: add crypto adapter implementation")
