Hi,

FYI, your patch has been queued to stable release 20.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/11/22. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/38dee9e84ab49a01d12f921e7590062948248a81

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: increase time waiting for PF reset completion

[ upstream commit d6a9f8fb26b8d6adaac20d6a303faa5c5ba4d5bc ]

On the case that PF and VF need to be reset, after the hardware reset is
complete, VF needs wait for 1 second to restore the configuration so
that VF does not fail to recover because PF reset isn't complete. But
the estimated time is not sufficient. This patch fixes it to 5 seconds.

Fixes: 2790c6464725 ("net/hns3: support device reset")
