The doc mentions out-of-tree module in order to support OVS tunnels,
but we do not support that module anymore, so there is no need to
mention that.  The docs are also listing the kernel version for the
XFRM support, but it is lower than what we require for the tunnel
support in general, so there is no need for that as well.
