This adds a device level support for Geneve -- Generic Network
Virtualization Encapsulation. The protocol is documented at
http://tools.ietf.org/html/draft-gross-geneve-00

Only protocol layer Geneve support is provided by this driver.
Openvswitch can be used for configuring, set up and tear down
functional Geneve tunnels.

So all this is really doing is enabling a Geneve socket for use by
Openvswitch.  Do you have any plans to enable a stand alone interface
like what we already have for VXLAN?

Yes, this is the basic protocol code that would be shared by all users
of Geneve. OVS is the first user but John Linville is looking at
adding support for connecting this to 'ip' as a non-OVS user.
