Hi,

FYI, your patch has been queued to stable release 20.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/14/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/58fbfecc2a176904fcdd738e0a544029bb278c20

Thanks.

Luca Boccassi

Subject: [PATCH] net/iavf: fix RSS key access out of bound

[ upstream commit 8ce5678f28a80871c9f4ef41ef52ba206ef5a17f ]

The array rss_key has size 'vf->vf_res->rss_key_size', the array index
should be less than that.

Fixes: 69dd4c3d0898 ("net/avf: enable queue and device")
