Subject: [dpdk-stable] patch 'net/hns3: remove meaningless packet buffer rollback' has been queued to stable release 19.11.9
Date: Thu, 10 Jun 2021 14:06:36 +0200	[thread overview]
Message-ID: <20210610120641.885862-48-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/0ace7116f833fa1aa540fc6d7b7854d4afc37bf7

Thanks.

Christian Ehrhardt <christian.ehrhardt@canonical.com>

Subject: [PATCH] net/hns3: remove meaningless packet buffer rollback

[ upstream commit 47ce649fd30c89d95c420a015f9eef7f215bb386 ]

Packet buffer allocation and hardware pause configuration fail normally
when a reset occurs. If the execution fails, rollback of the packet
buffer still fails. So this rollback is meaningless.

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