[dpdk-stable] patch 'distributor: fix scalar matching' has been queued to LTS release 18.11.11

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/24/20. 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-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/faf47ff9cdad6bfb0a4863ec184ec32d8656ccd1

Thanks.

Kevin.

Subject: [PATCH] distributor: fix scalar matching

[ upstream commit 626ceefbf4e1786ded4fed6a4987e3f1d370e9c0 ]

Fix improper indexes while comparing tags.
In the find_match_scalar() function:
* j iterates over flow tags of following packets;
* w iterates over backlog or in flight tags positions.

Fixes: 775003ad2f96 ("distributor: add new burst-capable library")
