I have a question Jiri: What kind of flower is this? ;->
Very nice - Glad Dave pushed you to go this direction.
For a usable classifier that performs reasonably well, i think
this one is going to look good.

My suggestion is to not add TCA_FLOWER_POLICE attribute.
Policers can be added via TCA_FLOWER_ACT (which is the modern
way to do it). Infact i would suggest even in your iproute2
code, please kill the conditional that tries to parse for
TCA_FLOWER_POLICE

Other than that:
