This petch-set extend the modify field action API to support 2 special
cases.
1. Modify field when the relevant header appears multiple times inside
same encapsulation level.
2. Modify Geneve option header which is specified by its "type" and
"class" fields.
In current API, the header type is provided by "rte_flow_field_id"
enumeration and the encapsulation level (inner/outer/tunnel) is
specified by "data.level" field.
However, there is no way to specify header inside encapsulation level.
For example, for this packet:
eth / mpls / mpls / mpls / ipv4 / udp
the both second and third MPLS headers cannot be modified using this
API.
