patch 'net/i40e: fix IPv6 GTPU handling' has been queued to stable release 23.11.7

[Shani Peretz]

Hi,

FYI, your patch has been queued to stable release 23.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/05/26. 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/shanipr/dpdk-stable

This queued commit can be viewed at:
https://github.com/shanipr/dpdk-stable/commit/586cdb5f3767e037e09efdf231d63c132e007519

Thanks.

Shani

Subject: [PATCH] net/i40e: fix IPv6 GTPU handling

[ upstream commit 089e093ee9e6d3bea5721dc17c79091aa59114b2 ]

GTP tunnel code declares support for IPv6 GTPU flows but does not
actually handle IPv6 flow pattern item, resulting in incorrect parsing
for IPv6 GTPU flows. Add IPv6 flow item handling.

Fixes: 47ba0398da3f ("net/i40e: add cloud filter parsing function for GTP")
