Subject: [dpdk-stable] patch 'net/qede: fix port reconfiguration' has been queued to LTS release 18.11.9
Date: Fri,  5 Jun 2020 19:24:57 +0100
Message-ID: <20200605182525.22483-60-ktraynor@redhat.com> (raw)
In-Reply-To: <20200605182525.22483-1-ktraynor@redhat.com>

Hi,

FYI, your patch has been queued to LTS release 18.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/10/20. 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/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/8cd93f836bec14d0df67c59ede1dd4639a7ad833

Thanks.

Kevin.

Subject: [PATCH] net/qede: fix port reconfiguration

[ upstream commit 05ccc9d8a9f9338b1cb4ae515c60c60f8b7f518d ]

This patch fixes deallocation of all fastpath resources unconditionally,
when re-configuring the device. When re-allocating resources PMD depends
on application to explicitly setup the Rx/Tx queue.

Deallocation of all the resources is only required if the Rx/Tx queue
configuration changes. For other scenarios like KNI MTU change we'd keep
existing configuration.

Fixes: 8de0c4201926 ("net/qede: fix odd number of queues usage in 100G mode")
Fixes: dd28bc8c6ef4 ("net/qede: fix VF port creation sequence")
