[dpdk-dev] [PATCH v3 15/21] net/mlx5: remove useless arguments in hrxq API

[Nelio Laranjeiro]

RSS level is necessary to had a bit in the hash_fields which is already
provided in this API, for the tunnel, it is necessary to request such
queue to compute the checksum on the inner most, this last one should
always be activated.
