1 - interface-DPO
Used in the Data-plane to change a packet's input interface
2 - MPLS multicast FIB entry
Same as a unicast entry but it links to a replicate not a load-balance DPO
3 - Multicast MPLS tunnel
Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to .
4 - Resolve a path via a local label (of an mLDP LSP)
For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP.
5 - MPLS disposition path sets RPF-ID
For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet.
6 - RPF check with per-entry RPF-ID
An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.

1 - use the SR policy to construct the replicate DPO. Each bucket therein is a SR tunnel.
2 - install a special mfib entry that links via this replicate
3 - forwarding is now mfib-lookup -> replicate -> sr_rewrite (per-tunnel)
no need for a separate sr_replicate node.
4 - Stack the sr tunnel on the forwarding DPO of the first-hop FIB entry.
no need for a second lookup post SR encap.
5 - fix some path-list lock leaks in the MFIB entry.

- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match
- Replication represented via a new replicate DPO.
- RPF configuration and data-plane checking
- data-plane signals sent to listening control planes.
The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast.
'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests.
Updated applications to use the new MIFB functions;
- IPv6 NS/RA.
- DHCPv6
unit tests for these are undated accordingly.
