Subject: [dpdk-stable] patch 'app/testpmd: fix burst percentage calculation' has been queued to LTS release 18.11.10
Date: Thu, 20 Aug 2020 16:33:21 +0100
Message-ID: <20200820153341.171927-16-ktraynor@redhat.com> (raw)
In-Reply-To: <20200820153341.171927-1-ktraynor@redhat.com>

Hi,

FYI, your patch has been queued to LTS release 18.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/25/20. 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/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/f1b7643e624b44873ae9673d14cf57c0fd277639

Thanks.

Kevin.

Subject: [PATCH] app/testpmd: fix burst percentage calculation

[ upstream commit 85de481a716a14a3eb89869928d96b539b1f0b62 ]

The burst % calculation can over flow due to multiplication.
Fix the multiplication and increase the size of variables to
64b.

Fixes: af75078fece3 ("first public release")
