Subject: [dpdk-stable] patch 'net/hns3: fix requested FC mode rollback' has been queued to stable release 19.11.9
Date: Thu, 10 Jun 2021 14:06:35 +0200	[thread overview]
Message-ID: <20210610120641.885862-47-christian.ehrhardt@canonical.com> (raw)
In-Reply-To: <20210610120641.885862-1-christian.ehrhardt@canonical.com>

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/12/21. 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/a93f977dc081895ca2f1482092878d1af38e44bb

Thanks.

Christian Ehrhardt <christian.ehrhardt@canonical.com>

Subject: [PATCH] net/hns3: fix requested FC mode rollback

[ upstream commit 19603f63fbb77f6ceddce9d36d20a6f5d7cdd4cf ]

Currently, the "requested_fc_mode" lacks rollback when enabling link
FC or PFC fails.
For example, this may result an incorrect FC mode after a reset.

Fixes: d4fdb71a0e7b ("net/hns3: fix flow control mode")
Fixes: 62e3ccc2b94c ("net/hns3: support flow control")
