[dpdk-stable] [PATCH 17/33] net/mlx5: fix ARM build

[Shahaf Shuler <shahafs@mellanox.com>]

From: Yongseok Koh <yskoh@mellanox.com>

[ upstream commit 264713ba1025e18436433a00fb14da8fc3f27101 ]

rdma-core v16 has a bug. The following compilation error occurs on ARM
hosts.

In file included
from drivers/net/mlx5/mlx5_glue.h:16:0,
from drivers/net/mlx5/mlx5_glue.c:11:
/usr/include/infiniband/mlx5dv.h:144:2: error: unknown type name 'off_t'
off_t   uar_mmap_offset;
^

As a temporary fix, sys/types.h is included in PMD. This has been fixed in
rdma-core v17. This can be removed when all the Linux distros are shipped
with rdma-core v17 or back-ported fix. As of now, RedHat 7.5 is known to
have rdma-core v16.
