patch 'net/virtio: propagate interrupt configuration error values' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/23. 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=a43f6d459a62bd5463e75a2bdc45580de690746b

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 5a475f73b084029444c7b83229aa9a4b6b3dac0c ]

rte_intr_vec_list_alloc() may fail because of different reasons which
are indicated by different negative errno values.

Fixes: d61138d4f0e2 ("drivers: remove direct access to interrupt handle")
