IB/mlx5: Add support for MPLS flow specification
This patch introduces support for the MPLS flow spec and allows the creation of rules that are matching on the MPLS label. Applying the rule matching depends on the flow specs order and the location of the MPLS in the spec list as there are different configurations to be made in the device in the cases of MPLSoGRE and MPLSoUDP vs. non-encapsulated MPLS.
