Hi,

FYI, your patch has been queued to stable release 19.11.14

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/18/22. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/3f705a2a4a38f6566c232664a4660fdd35e3cead

Thanks.

Subject: [PATCH] gro: fix chain index for more than 2 packets

[ upstream commit bc4a7f7ee0281d96b8d93ac2771135a670b4a00f ]

When more than two packets are merged in a flow, and if we receive
a 3rd packet which is matching the sequence of the 2nd packet the
prev_idx will be 1 and not 2, hence resulting in packet re-ordering
