[v1,2/2] net/mlx5/windows: implement sampling actions wrappers
Checks
Commit Message
This commit adds the Windows sampling actions wrappers (currently return
ENOTSUP): mlx5_os_flow_dr_create_flow_action_sampler() and
mlx5_os_flow_dr_create_flow_action_dest_array(). Using configuration
definitions HAVE_MLX5_DR_CREATE_ACTION_FLOW_SAMPLE and
HAVE_MLX5_DR_CREATE_ACTION_DEST_ARRAY the missing sampling DV structs
are added as stubs to windows/mlx5_glue.h file.
