[dpdk-dev] [PATCH 07/35] net/mlx5/windows: add stubs for MP requests

[Tal Shnaiderman <talshn@nvidia.com>]

From: Ophir Munk <ophirmu@nvidia.com>

Windows supports the primary process with no secondary process control.
This commit adds stubs for requests to start/stop the data-path to the
secondary process and for requests to start/stop a queue of the primary
process.
