This is in the FAQ.
### Q: Does Open vSwitch support OpenFlow meters?
A: Since version 2.0, Open vSwitch has OpenFlow protocol support for
OpenFlow meters. There is no implementation of meters in the Open
vSwitch software switch (neither the kernel-based nor userspace
switches).

Russell, you had some thoughts about SFC in OVN. I had the impression
that the approach you had in mind was more powerful than what John is
suggesting here, yet still not very complicated. I think you said that
you weren't going forward with it for now because other things were
higher priority.
