patch 'app/testpmd: fix packet segment allocation' has been queued to stable release 21.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/23/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/c18ad5cc3eec4b56421f4bd200aa1ba819044e9c

Thanks.

Kevin

Subject: [PATCH] app/testpmd: fix packet segment allocation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

[ upstream commit 1108c33e743f8be81e765165c8b3cf27d57a7220 ]

When --mbuf-size cmdline parameter is specified, the segments to scatter
packets on are allocated sequentially from these extra memory pools
(the mbuf for the first segment is allocated from the first pool, the
second one from the second pool, and so on, if segment number is greater
then pool’s the mbuf for remaining segments will be allocated from the
last valid pool).
A bug in comparing segment index with mbuf index caused wrong mapping
of one of the segments.

Fix the comparison.

Fixes: 2befc67ff679 ("app/testpmd: add extended Rx queue setup")
