[dpdk-dev] [PATCH v2 3/6] net/mlx5: flow type check before creating

[Bing Zhao]

When creating a flow, the driver mode needs to be checked in order
to call the corresponding functions. Now the driver mode checking
part is moved out of the flow creating function, then the flow could
be added into the correct tailq list.
