[Kevin Traynor <ktraynor@redhat.com>]

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 06/27/22. 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/e6f569043c5deef7d7052c82cdb5d442468bc8a0

Thanks.

Kevin

Subject: [PATCH] event/dlb2: fix check of QID in-flight

[ upstream commit 7767b849ab028db51474dcbd2a51bff3b5f4f81d ]

If QID inflights is set to an invalid value, it can cause the
PMD to hang.  This commit adds checks to make sure that the
value is valid before programming the hardware.

Fixes: 1857f1922ce2 ("event/dlb2: use new implementation of resource file")
