  Implement a generic modify rte flow API as described in RFC:
http://patches.dpdk.org/patch/85384/

This API allows modifying a destination header field with data from
a source header field. Number of bits to use from the source is specified.
Tag, Mark or Metadata can also be used as a source/destination to allow
saving/overwriting an arbitrary header field with a user-specified value.
Alternatively, an immediate value can be provided by a user as a source.

Outermost/innermost packet fields (and Tag array elements) are
accessible via the level parameter to facilitate the modification
of encapsulated packet header fields. The offset parameter provides
the flexibility to copy/set any part of a packet starting the
specified packet header field.
