    Hi Darrell, Ben,
    
    Thanks for your reply. Glad to hear that we are approaching useful candidate patch.
    
    What is the plan for disassemble and fragment for OVS+DPDK? Like
       1, received underlay vxlan fragmented packets,
       2, received overlay fragmented packets that will go through conntrack
       3, output packet with size > out_port_mtu


IP frag. is still on the radar:

I have a large dataset of information regarding IP frag usage from a widely 
distributed virtualization product.

However, I would like know your usage requirements for IP frag ?

Do you want it for feature parity reasons with the kernel or does it
solve some problems you are facing; can you explain your specific needs ?

        I think that Darrell (CCed) is working on that for OVS 2.8.  He has
        posted patches before.  I expect to see a revision of it pretty soon.
    
    NAT patches have been out for a while and a minor reversion will come out next week along with a separate series for ftp alg support.
    The NAT patches have been tested by a couple other folks, externally and internally, as well.
