patch 'app/crypto-perf: fix copy segment size' has been queued to stable release 23.11.1

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/15/24. 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=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=f0cfffc636bac0f4bf8c064a36de2cac27d4ca03

Thanks.

Subject: [PATCH] app/crypto-perf: fix copy segment size
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 7c31d17f68f615c31811afa1830fa0e38956ffc4 ]

For the case crypto device requires headroom and tailroom,
the segment_sz in options also contains the headroom_sz
and tailroom_sz, but mbuf's data_len is user's segment_sz
without headroom_sz and tailroom_sz. That means the data
size to be copied should use user's segment_sz instead
of options->segment_sz.

This commit fixes the copy segment size calculation.

Fixes: 14864c4217ce ("test/crypto-perf: populate mbuf in latency test")
