[PATCH 2/4] vdpa/mlx5: Move some definitions to a new header file

From: Eli Cohen
Date: Tue Oct 18 2022 - 07:13:20 EST


Move some definitions from mlx5_vnet.c to newly added header file
mlx5_vnet.h. We need these definitions for the following patches that
add debugfs tree to expose information vital for debug.
