Initial GENEVE TUNNEL implementation and tests.
Notes on this first implementation:
* First version of the implementation does NOT support GENEVE OPTIONS
HEADER: it isn't well understood what the purpose of the OPTIONS will be and/or
what content would be placed in the variable option data;
Once the IETF work will evolve and further information will be available
it could be possible to modify the frame rewrite to contemplate the
actual GENEVE OPTIONS.
