[dpdk-stable] patch 'net/hns3: remove read when enabling TM QCN error event' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/5d84f2b422adc0856f1404f6237ddfc6a7f64c3e

Thanks.

Subject: [PATCH] net/hns3: remove read when enabling TM QCN error event
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 3903c05382c55ce36837405141534c6be042c2a2 ]

According to the HW manual, the read operation is unnecessary when
enabling TM QCN error event, so remove it.

Fixes: f53a793bb7c2 ("net/hns3: add more hardware error types")
