[dpdk-stable] patch 'net: fix encapsulation markers for inner L3 offset' has been queued to LTS release 18.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/28/19. 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. 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/88cf98fe893f1bfaaba6aa0e66e07a5a9a612e44

Thanks.

Kevin Traynor

Subject: [PATCH] net: fix encapsulation markers for inner L3 offset

[ upstream commit 6bf0912011eed76285a6acf2ddb9b126008b6339 ]

The API to prepare checksum offloads employs outer
IP checksum flag to tell regular IPv4 packets from
tunnel packets with outer IPv4 encapsulation. This
flag cannot serve as a marker for the said purpose
because a packet can have outer IPv4 encapsulation
and may not have outer IP checksum offload request.

Fix the API by changing the said criterion to test
outer IPv4 flag rather than outer IP checksum flag.
Use simpler spelling of the conditional expression.

Fixes: 4fb7e803eb1a ("ethdev: add Tx preparation")
