Hi,
FYI, your patch has been queued to stable release 23.11.2
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/14/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging
This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=db50b74b3c423660806ad1f69b5763e1cf690276
Thanks.

Subject: [PATCH] net/ngbe: fix hotplug remove
Cc: Xueming Li <xuemingl@nvidia.com>
[ upstream commit c602202c346663572043b408a27cb98e20f31886 ]
This bug occurs in OpenvSwitch. After adding a port bound to vfio-pci
to ovs, detach it from ovs and then unbind it from vfio-pci(that is
hotplug) will cause operating system to get stuck.
Fixes: 6ee7e574cd48 ("net/ngbe: support probe and remove")
