[dpdk-dev] [PATCH v1 3/8] net/mlx5: move socket files under Linux directory

[Ophir Munk <ophirmu@mellanox.com>]

mlx5_socket.c file is using APIs which are Linux specifics.  Therefore
move it (including mlx5_socket.h) from net/mlx5 directory to
net/mlx5/linux directory. This commit also updates the Makefile and
the meson files.
