Hi,

FYI, your patch has been queued to stable release 20.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/20/22. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/31080d4c6216c9f8abfe6107235324a878c01eb2

Thanks.

Subject: [PATCH] net/bnxt: fix xstats query

[ upstream commit c05c22f9b8032c2974de7042ba8c38fb42ed7c82 ]

Fix incorrect memset in bnxt_dev_xstats_get_op.
In bnxt_dev_xstats_get_op(), the PMD is not zeroing the whole
buffer supplied by the application. This can end up passing
junk statistics values to the application when the FW does not
support extended stats on a function.
Fixed to call memset() with correct size.

Fixes: f55e12f33416 ("net/bnxt: support extended port counters")
