Meters were introduced to the Linux kernel in 4.15, so earlier versions don't support them.  Unfortunately, all the released upstream kernels have a bug in them that prevents meters from being used properly.  A patch was recently accepted upstream, which means that new releases (including maintained older kernels) should receive the fix.

The OVS 2.10 out-of-tree kernel module will contain meters on all supported kernels.

All of that said, unless you need meters, you can just ignore that message; it's just informational.
