From: Leon Romanovsky <leonro@xxxxxxxxxxxx> Direct verbs feature provides fast data path execution by implementing verbs directly over hardware specification. It consists from the two parts: * Exported functions to translate internal mlx5 structures to be accessible by user applications. * Inline functions, enums and defines to simplify programmer's life. This patch adds one header file (mlx5dv.h) with general, CQE and WQE data.
