Ahh, I was thinking the problematic ones, the ones adding extra fields than the 
protocol header, 'rte_flow_item_eth', 'rte_flow_item_vlan' and there was one 
more I guess, but you are right, all needs be updated.

So there are more to be updated, are you planning to work on any more of them in 
this release?

btw, thanks again for addressing this issue.
