Andre, thank you for your information, It is the first time for me to know 
this, can you share us how we can enable not-use-conntrack option for this? I 
want to try it.

Subject: Re: [sfc-dev] ovs nsh patches have been ported into ovs 2.6.1

FYI, NetVirt can be configured to not use conntrack for security groups.

Hi, folks

Current ovs nsh patches https://github.com/yyang13/ovs_nsh_patches/ are only 
for ovs 2.5.98, so it can’t be built on Linux kernel 4.1 and above, moreover 
this ovs DPDK version can’t support conntrack, NetVirt depends on conntrack to 
implement security group.

Now I have ported https://github.com/yyang13/ovs_nsh_patches/ to ovs 2.6.1, so 
it can be built on almost any Linux distribution (kernel version >= 3.11, <= 
4.8) , to be important, this ovs DPDK version can support conntrack, so we can 
use this ovs DPDK version for NetVirt + SFC integration with vhostuser and 
security group support.

The patchset for ovs 2.6.1 is 
https://github.com/yyang13/ovs_nsh_patches/tree/master/v2.6.1, 
https://github.com/yyang13/ovs_nsh_patches/blob/master/start-ovs-deb-2.6.1.sh 
is used to build and install debian packages on Ubuntu, ODL can adapt to it 
without any change, welcome your tries.
