[ovs-dev] OpenFlow rule deletion during port destroy

[Zoltan Kiss]

Hi,

I came accross a problem recently, where the destroying of a VM's port 
(with ovs-vsctl del-port) seems to blow away other OpenFlow rules from 
the userspace. It seems to me logical for ovs-vswitchd to delete the 
associated OpenFlow rules when the port is deleted, but I couldn't find 
in the code where it happens. And as far as I can see in the OpenFlow 
connection's monitoring, the controller doesn't do it either.
So my question is, who does delete the rules associated to a port during 
teardown? I might have overlooked something in the ovs-vswitchd code, 
and it happens deferred somewhere else, but can someone point me there?

Regards,

Zoltan Kiss
