Hi,

FYI, your patch has been queued to stable release 22.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/17/24. 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/18b7942cef2ec0c26c7999550d72f4558e456cd3

Thanks.

Luca Boccassi

Subject: [PATCH] net/ena: fix checksum handling

[ upstream commit f66055c7564050e55c7eab147d039bf01048829a ]

This change fixes an issue where a non tcp/udp packet can be indicated
to have an invalid csum. If the device erroneously tries to verify the
csum on a non tcp/udp packet it will result in false indication that
there is a csum error. This change make the driver ignore the
indication for csum error on such packets.

Fixes: 84daba9962b5 ("net/ena: add extra Rx checksum related xstats")
