Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/05/26. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/83680a2ccc11413946cacf1112c20945420a3486

Thanks.

Luca Boccassi

Subject: [PATCH] net/txgbe: enable Tx descriptor check per queue

[ upstream commit af2a849b0a12139ca098ca314546674e3ae8ac7e ]

Now lib security is enabled by default, and cannot be disabled if the
driver is intended to be used. So Tdm_desc_chk is always unable to enable.
Remove this restriction, and just enable the corresponding queue check.

Fixes: 0eabdfcd4af4 ("net/txgbe: enable Tx descriptor error interrupt")
