In in-network service instance case, when service scaling
is more than one, all the instances are going to have the
same mac address and IP address. Inet route points to
ECMP composite nexthop but FDB route does not point to ECMP
nexthop. So when neighbour request is received from service VM
Vrouter needs to send response on the incoming interface
rather bridging the reply packet, as FDB route points
to arbitrarly any of the service VM encap L2 nexthop.
After preparing the reply packet,bridge lookup is done
and outgoing interface is compared against ingress interface.
If they are not same, reply packet is transmitted on
ingress interface.
