Operations, Administration, and Maintenance (OAM) ping and traceroute support for SRv6 uSID

We support pinging an SRv6 micro segment Identifier (uSID) to verify that the uSID is reachable and is locally programmed at the target node. We also support tracerouting to an SRv6 uSID for hop-by-hop fault localization as well as path tracing to a uSID. As part of this feature, we support SRv6 uSID ping and traceroute for the following configurations: ? SRv6 IS-IS ping and traceroute for End behavior with NEXT-CSID (uN)/uN+End.X behavior with NEXT-CSID (uA)/uN+End.DT behavior with NEXT-CSID (uDT) SIDs. ? SRv6 IS-IS ping and traceroute for compressed SID (compressed SID to be provided by user) for uN/uA/uDT. ? SRv6 uSID-stack ping and traceroute for uN/uN+uA/nN+uDT SIDs. We've introduced the following commands: ? ping srv6 spring-te micro-sids-stack nexthop-address
