You must not change ofp_match, because its format is fixed by the
OpenFlow 1.0 standard and there is no mechanism for extending it.
Instead, you should define and use NXM ("Nicira Extensible Match")
fields, which are extensible. OpenFlow 1.2 adopts an NXM variant
called OXM that includes definitions for MPLS; you should adapt those
to NXM.
