Hi,

FYI, your patch has been queued to stable release 19.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before December 10th 2021. 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/80d02f329d70b2b9be3fcaa8200d0e2b88f12ab1

Subject: [PATCH] net/ixgbe: fix Rx multicast statistics after reset

[ upstream commit 8908691632a51a81d6ce27d3d12a8781842a7518 ]

In the implementation of the VF driver ixgbevf_update_stats to obtain
statistics, the multicast count hw_stats->vfmprc has been obtained,
but it is not cleared in the corresponding ixgbevf_dev_stats_reset
interface.

Fixes: abf7275bbaa2 ("ixgbe: move to drivers/net/")
