patch 'net/virtio: propagate interrupt configuration error values' has been queued to stable release 21.11.5

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/25/23. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/2c2d4e88a8a6e933f4969c34b8f2097e197fb35b

Thanks.

Kevin

Subject: [PATCH] net/virtio: propagate interrupt configuration error values

[ 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")
