Subject: [dpdk-stable] patch 'net: explicit cast of IP checksum to 16-bit' has been queued to LTS release 17.11.5
Date: Thu, 3 Jan 2019 00:13:50 -0800 [thread overview]
Message-ID: <20190103081400.14191-27-yskoh@mellanox.com> (raw)
In-Reply-To: <20190103081400.14191-1-yskoh@mellanox.com>
Hi,
FYI, your patch has been queued to LTS release 17.11.5
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 01/04/19. 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. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.
Thanks.
Yongseok
