Hi Franck,
 First of all, thanks for your help. I messed up on the Netfilter and OVS.
I have one more doubt, if you can help me I will be very grateful. My
project aims to add Application layer support to OpenFlow, adding one more
field in the flow table; I would like to know if it is viable to create
this support in the ovs (using regex or anything else that matches
application headers like Http). Any help will be appreciated.

Thanks in advance.
