[dpdk-dev] [PATCH v2 1/4] net/mlx4: enable debug logs dynamically

[Matan Azrad]

From: Thomas Monjalon
> The macro DEBUG was doing nothing if not compiled with
> RTE_LIBRTE_MLX4_DEBUG.
> 
> As it is not used in the data path, it can be always enabled at compilation time.
> Then it can be enabled at runtime with:
>         --log-level pmd.net.mlx4:debug
>
