First four vxlan patches extends vxlan so that openvswitch
can share vxlan recv code. Rest of patches refactors vxlan
data plane so that ovs can share that code with vxlan module.
Last patch adds vxlan-vport to openvswitch.

v6 series splits second patch into two and has few style fixes.
v5 series disallow any udp port sharing between
kernel-vxlan and ovs-vxlan as suggested by Stephen Hemminger.
