> [OVS]Flow rules to drop Broadcast/Multicast traffic on tunnel ports are not added in
bridge flow table 
> Steps to reproduce:
> ================
> 1.Bring up CS in advanced zone with two hosts in xen cluster
> 2.Add physical network with isolation type GRE
> 3.Create an isolated network offering with connectivity service and OVS asc the provider
> 4.Create a user account and deploy one vm with above network offering and make sure that
vm comes on host1 and VR comes on host2
> 5.Verify the flow table on the ovs bridge created for this network
> Result:
> ======
> flow table rules to drop multicast and broacast traffic on tunnel ports are not added
on the host where VR is running but the same rules are added on the host where vm is running
> VR is running on the following host:
