Hi,

FYI, your patch has been queued to stable release 19.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/12/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/e818762474aea4d0b9e53d16aeba6e86aa9f53e6

Thanks.

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")
