Merge branch 'geneve'

Andy Zhou says:

====================
Add Geneve tunnel protocol support

This patch series adds kernel support for Geneve (Generic Network
Virtualization Encapsulation) based on Geneve IETF draft:
http://www.ietf.org/id/draft-gross-geneve-01.txt

Patch 1 implements Geneve tunneling protocol driver

Patch 2-6 adds openvswitch support for creating and using
Geneve tunnels by OVS user space.

v1->v2:   Style fixes: use tab instead space for Kconfig
	  Patch 2-6 are reviewed by Pravin Shetty, add him to acked-by
	  Patch 6 was reviewed by Thomas Graf when commiting
	    to openvswitch.org, add him to acked-by.
