I think the commit title should reflect that this commit adds support for
GRE and MPLS items to rte_flow, testpmd changes are only a consequence.

API documentation must be updated accordingly, see:
doc/guides/prog_guide/rte_flow.rst
Same comments about RTE_FLOW_ITEM_TYPE_NVGRE added by another series. You
should mention there's a dependency between them.
