I see that the seq is incremented by a call to udpif_revalidate()  - this is trigerred by setting the backer->need_revalidate  
- what is the criteria to set this for flow cache revalidation ?
- is the flow deletion is indeed based on LRU (Least Recently Used) algorithm ?  or flows are deleted when  exceeding a threshold of pps ?

I see that a call to should_revalidate()  is made only if (ukey->reval_seq != reval_seq); What is this sequence ? who increments this sequence number ? inc. frequency ?
