patch 'compress/mlx5: fix output Adler-32 checksum offset' 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 04/11/23. 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/log/?h=22.11-staging/commit/2a091b2f313b48586a31585f278d14e9938ef6d3

Thanks.

Subject: [PATCH] compress/mlx5: fix output Adler-32 checksum offset
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit d54dd89f49ded1e2d8d0e83710b2347a5de4d7f5 ]

After de/compress dequeue, the output checksum is copied into the op
structure. The "output_checksum" field in op structure is "uint64_t"
type, and the 32-bit checksums (CRC32, Adler-32) are copied into the
lower 32 bits.

When both CRC32 and Adler-32 are configured, CRC32 is copied into the
lower 32 bits and Adler-32 into the upper 32 bits.
However, in mlx5 PMD Adler-32 without CRC, is mistakenly copied into the
upper 32 bits.

This patch updates Adler-32 output checksum to be copied into the
lower 32 bits.
