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/cbcc18305c5f7cc6827d0f45473e998574c193e0
Thanks.

Use device configured Rx offloads instead of hardcoded values while
draining work.
Fixes: e8594de2731d ("event/cnxk: implement event port quiesce function")
