  To: dev, Matan Azrad; +Cc: Ophir Munk

File mlx5_nl.c is using Netlink APIs which are Linux specifics.
Move it (including file mlx5_nl.h) to common/mlx5/linux directory.

  To: dev, Matan Azrad; +Cc: Ophir Munk

File mlx5_nl.c is using Netlink APIs which are Linux specifics.
Move it (including file mlx5_nl.h) to common/mlx5/linux directory.

  To: dev, Matan Azrad; +Cc: Ophir Munk

File mlx5_common.c includes both specific and non-specific Linux APIs.
Move the Linux specific APIS into a new file named linux/mlx5_common_os.c.
