patch 'net/iavf: fix outer UDP checksum offload' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/01/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=6e50af124fb99278fe3cea4ff7d87bebca856704

Thanks.

Subject: [PATCH] net/iavf: fix outer UDP checksum offload
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit feb4f66b5a8c8fc32a7e721368728dd53f541e3b ]

Currently, when dealing with UDP tunnel pkts checksum offloading,
the outer-udp checksum will be offloaded by default. So the
'csum set outer-udp hw/sw' command does not work.

This patch fixes judgment of the EIPT flag and enables the
'csum set outer-udp hw/sw' command by adding judgment for the
outer-udp checksum offload flag.

Fixes: 0c550022fb82 ("net/iavf: fix Tx descriptors for IPsec")
