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

Subject: [PATCH] net/mvpp2: fix port speed overflow

[ upstream commit 8fa07a68a6f842aa81b8949976e8088e2b6318a3 ]

ethtool_cmd_speed return uint32 and after the arithmetic
operation in mrvl_get_max_rate func the result is out of range.
