Cool. I will see them on netdev, but if you are using them for real some 
examples would be usefull on here. It seems like ages ago Thomas was 
doing ematch/meta stuff and until now I've not seen one example.

To Leigh - there are the other things you can do with tc actions like 
pipe/reclassify/continue. They are (partially/minimally) documented in 
iproute2's doc/actions/*.

I do have a problem with actions-general (maybe it's just the way I read 
it), but the comments in the example in that just seem wrong.

They are to do with policers/shared meters more than classification, but 
the comments and the phrase shared meter hold up the possibility of 
doing some cool stuff that in reality turns out to be impossible.
