I am now confused, it is something in OVS or in Controller or in Plugin, did we 
get to any conclusion ? Anyway Jamo or Mohamed guys plz can you try it on 
actual master or carbon branch with org.opendaylight.openflowplugin.impl DEBUG 
and send me the karaf logs ?

If this issue is still an issue :)

Predmet: Re: [netvirt-dev] [openflowplugin-dev] FW: br-int become slave and 
disconnect from ODL

for those that can reproduce this manually, getting that wireshark would be 
helpful. If we
can pin this as a bug in OVS then we can figure out how to get it fixed there.

for the ODL csit that sees this, we do collect the ovs log but there was 
nothing I saw that
made me think OVS was in the wrong. example here:
