[dpdk-users] Enable MLX5 driver v20.11

[Raslan Darawsheh]

Hi Gerry,

Starting V20.11 the build system was switched to use meson only,
And if you have necessary packages for MLX5 (a.k. rdma-core) it will be built automatically.

As for your question if you still don't need to bind mlx5 driver that's true, its still valid.

Kindest regards,
Raslan Darawsheh
