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/mlx4: fix initialization of struct members

[ upstream commit d924d6b964d1dd4a720f61051c14507428b62e95 ]

This patch fixes compilation errors with meson and the clang
compiler caused by some of the struct members not being
initialized.

```
../drivers/net/mlx4/mlx4_mr.c:357:37: error: missing field 'end'
initializer [-Werror,-Wmissing-field-initializers]
                struct mlx4_mr_cache entry = { 0, };
                                                  ^
../drivers/net/mlx4/mlx4_mr.c:401:36: error: missing field 'end'
initializer [-Werror,-Wmissing-field-initializers]
                        struct mlx4_mr_cache ret = { 0, };
                                                        ^
../drivers/net/mlx4/mlx4_mr.c:691:35: error: missing field 'end'
initializer [-Werror,-Wmissing-field-initializers]
                struct mlx4_mr_cache ret = { 0, };
                                                ^
```

The compilation errors reproduce with
clang version 3.4.2 (tags/RELEASE_34/dot2-final) on RHEL.

Fixes: 9797bfcce1c9 ("net/mlx4: add new memory region support")
