[dpdk-stable] patch 'app/test: fix IPv6 header initialization' has been queued to stable release 20.11.3

Hi,

FYI, your patch has been queued to stable release 20.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/14/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/60c3dfd45f8ac5b248dd08acf73d93705908472a

Thanks.

Luca Boccassi

Subject: [PATCH] app/test: fix IPv6 header initialization

[ upstream commit a906371d2758df7260640873d93f888724759448 ]

Fix two issues found when writing PMD unit tests for HW ptype and
L4 checksum offload:

   - The version field in the IPv6 header was being set to zero,
     which prevented hardware from recognizing it as IPv6. The
     IP version field is now set to six.
   - The payload_len field was being initialized using host byte
     order, which (among other things) resulted in incorrect L4
     checksum computation. The payload_len field is now set using
     network (big-endian) byte order.

Fixes: 92073ef961ee ("bond: unit tests")
