Maybe first mention that it is possible for multiple filters in software
to share the same policer. Something like:

"
It is possible for several tc filters to share the same police action by
specifying the action's index when installing the filters.
    
Propagate this index to device drivers through the flow offload
intermediate representation, so that drivers could share a single
hardware policer between multiple filters.
