Hi,

FYI, your patch has been queued to stable release 19.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/12/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/ba81e4b31721957e9140494f7ccc4149962de6d5

Thanks.

Subject: [PATCH] net/hns3: increase VF reset retry maximum

[ upstream commit b25987fa7e25b3ba852f9433d22761c006884205 ]

When the device is very busy, VF reset may have to be
retried many times to succeed, leading to the current
max reset fail retry count not enough.

Modify max reset fail retry count to 30 to enhance
the reliability of reset function.

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