Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/29/19. 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/accb06f7dca969ee93204bd1d41f1214a5e604ca

Thanks.

Kevin.

Subject: [PATCH] net/mlx5: fix Rx CQ doorbell synchronization on aarch64

[ upstream commit 94a24aaf6c5bd0a03c2828e7411d30a4fc0ac075 ]

The Rx completion queue doorbell field needs to be updated after
the last CQE decompressed. For the weaker memory model processors,
the compiler barrier is not sufficient to guarantee the order of
these operations, so use the coherent I/O memory barrier to make
sure these fields are updated in order.

Fixes: 570acdb1da8a ("net/mlx5: add vectorized Rx/Tx burst for ARM")
