Hi,

FYI, your patch has been queued to stable release 20.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/10/23. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/aca18a766ad56e413a287316c4dea56eea6438ce

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: remove reset log in secondary

[ upstream commit 5394df455749f60614a19d791d1d73c26b74dea1 ]

The reset event is checked and done in primary. And the secondary
doesn't check and display reset log. There is a patch to remove the
check code for secondary. please see commit a8f1f7cf1b42 ("net/hns3:
fix crash when secondary process access FW")

This patch removes the redundant log print of reset.

Fixes: a8f1f7cf1b42 ("net/hns3: fix crash when secondary process access FW")
