Hi,

FYI, your patch has been queued to stable release 20.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/14/21. 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:

Subject: [PATCH] crypto/mvsam: fix session data reset

[ upstream commit 03e73e8572f112bd3714cd90c491a6570330189c ]

This patch fix wrong clear memory session pointer.

When call mrvl_crypto_pmd_sym_session_clear function,
it might cause the following error:
CRYPTODEV: set_sym_session_private_data() line 497:
Set private data for driver 1 not allowed

This fix set zeroes to mrvl_crypto_session pointer instead to
rte_cryptodev_sym_session pointer, and will verify that
rte_cryptodev_sym_session pointer will not lose data such as
nb_drivers.

Bugzilla ID: 646
Fixes: 8a61c83af2fa ("crypto/mrvl: add mrvl crypto driver")
