[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/11/23. 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/log/?h=22.11-staging/commit/b836bb43cfaa8a12ecfac6e837d4c20817bf99fd

Subject: [PATCH] net/iavf: fix device stop during reset
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 24b8bc86dc489ab77d7de7626cc6af7ac9eaba0b ]

The rte_eth_dev_stop will return wrong value as error will return from
iavf PMD during device reset.

This patch is a work around to fix it by return 0 in dev_stop during
device reset.

Fixes: 69dd4c3d0898 ("net/avf: enable queue and device")
