Hi,

Thanks for your answer. Indeed I build ovs from sources and I didn't 
configure it with those options. Where did you find those options? I 
couldn't find them in the official INSTALL.Debian file (or any other 
file in the git repo).

And if you could tell me, where can I find all the configure options?

Thanks,
