[dpdk-dev] [PATCH 5/6] net/mlx5: remove the DV support macro checking

Bing Zhao bingz at mellanox.com
Mon Feb 3 14:32:14 CET 2020


Some structures are defined in the mlx5_flow header file and only
used for flows with DV driver type. When using inbox driver, the DV
mode is not supported. But the code is unique and there is no need
to use pre-processing macro since all code could be compiled.
