Hi,
FYI, your patch has been queued to stable release 18.08.1
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/08/18. 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. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.
Thanks.
Kevin Traynor

Subject: [PATCH] net/mlx5: fix initialization of struct members
[ upstream commit 0c15f3c010322853078c20a2a9926d3fb5986548 ]
This patch fixes compilation errors with meson and the clang
compiler caused by some of the struct members not being
initialized.
```
../drivers/net/mlx5/mlx5_mr.c:345:37: error: missing field 'end'
initializer [-Werror,-Wmissing-field-initializers]
struct mlx5_mr_cache entry = { 0, };
^
../drivers/net/mlx5/mlx5_mr.c:389:36: error: missing field 'end'
initializer [-Werror,-Wmissing-field-initializers]
struct mlx5_mr_cache ret = { 0, };
^
../drivers/net/mlx5/mlx5_mr.c:691:35: error: missing field 'end'
initializer [-Werror,-Wmissing-field-initializers]
struct mlx5_mr_cache ret = { 0, };
^
```
The compilation errors reproduce with
clang version 3.4.2 (tags/RELEASE_34/dot2-final) on RHEL.
Fixes: e1114ff6a5ab ("net/mlx5: support e-switch flow count action")
Fixes: db48f9db5d9f ("net/mlx5: support new flow counter API")
Fixes: 974f1e7ef146 ("net/mlx5: add new memory region support")
Fixes: 65c9d24170c9 ("net/mlx5: enable loopback by configured mode")
Fixes: 87011737b715 ("mlx5: add software counters")
