> When using Verbs flow engine to create flows, GRE Verbs spec was put at
> the end of specs list. This created problems for flows matching MPLSoGRE
> packets. In generated specs list MPLS spec was put before GRE spec, but
> Verbs API requires that MPLS spec must be put in its exact location in
> protocol stack.
> 
> This patch fixes this behavior. Space for GRE Verbs spec is reserved at its
> exact location. MPLS Verbs is inserted at its exact location as well. GRE spec is
> filled after all flow items are parsed.
