According to:
https://github.com/openvswitch/ovs/blob/master/FAQ.md
...v3.14 *is* the latest kernel supported by the out-of-tree OVS
kernel module, given that ovs 2.4.x isn't tagged yet and "git
log v2.3..master" doesn't reveal anything obviously aimed at
providing >v3.14 compatibility.
Can you try with the in-tree OVS module?
