* Loopback IP changes for multi ASIC devices multi ASIC will have 2 Loopback Interfaces - Loopback0 has globally unique IP address, which is advertised by the multi ASIC device to its peers. This way all the external devices will see this device as a single device. - Loopback4096 is assigned an IP address which has a scope is within the device. Each ASIC has a different ip address for Loopback4096. This ip address will be used as Router-Id by the bgp instance on multi ASIC devices. This PR implements this change for multi ASIC devices Signed-off-by: Arvindsrinivasan Lakshmi Narasimhan <arlakshm@microsoft.com>
