Bug Description

Right now the multicast packets from service interface are dropped unconditionally. This is leading to ARP request getting dropped as well. As a result, traffic originating from service instance can not reach another service instance, as ARP does not get resolved.

Enabling ARP processing on Service interface

To avoid the flooding of packets on service interface, BUM traffic on
service interface is drooped. This is fine as service instance does not
communicate to another sevice instance. This fix enables the ARP processing on
service instance interface so that it can communicate to another service
instance. If ARP algorithm choses to flood the ARP request, it is still
dropped, so that it would not loop.
