[dpdk-stable] patch 'net/ixgbe: fix Rx multicast statistics after reset' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/9f02c498bf8f31e2dda1d2665ff0fe015265dfa6

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ 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/")
