You should see something like this in your dmesg output:

[167126.796728] openvswitch: Open vSwitch switching datapath 2.10.90
[167126.796869] openvswitch: LISP tunneling driver
[167126.796870] GRE over IPv4 demultiplexor driver
[167126.797172] openvswitch: GRE over IPv4 tunneling driver
[167126.797406] openvswitch: GRE over IPv6 tunneling driver
[167126.797526] openvswitch: Geneve tunneling driver
[167126.797528] openvswitch: VxLAN tunneling driver
[167126.797529] openvswitch: STT tunneling driver
