[dpdk-stable] patch 'net/hns3: fix processing Tx offload flags' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/a7bf8336a2d7fed8e654a86dc99ef96bdec03294

Thanks.

Subject: [PATCH] net/hns3: fix processing Tx offload flags
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit a1d0caa92c7fe43cef7a9f6ac4772e0eecd4a011 ]

Currently, if the PKT_TX_TCP_SEG and PKT_TX_TCP_CKSUM offload flags set
in the same time, hns3 PMD can not process the descriptors correctly.

This patch fixes it by adding the processing of this situation.

Fixes: fb6eb9009f41 ("net/hns3: fix Tx checksum with fixed header length")
