The out of tree OVS module only tries to track the mainline kernel and
backports from a few common distributions.  OVS is included as part of
Linux since 3.3 so you might be able to use it with a version of the
RT patchset from there or newer.

You could use the userspace datapath but the performance is
significantly worse than the kernel version.
