patch 'net/hns3: simplify queue DMA address arithmetic' has been queued to stable release 19.11.11

[christian.ehrhardt at canonical.com]

Hi,

FYI, your patch has been queued to stable release 19.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before December 10th 2021. 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/eba0dc77635f4120d9bfcb3bd7391842f1a42171

Thanks.

Subject: [PATCH] net/hns3: simplify queue DMA address arithmetic

[ upstream commit f658f415814add688ade5783200143d14eefc51a ]

The patch obtains the upper 32 bits of the Rx/Tx queue DMA address in one
step instead of two steps.

Fixes: bba636698316 ("net/hns3: support Rx/Tx and related operations")
