2017-03-17MPLS performance improvments.Neale Ranns2-31/+119
1 - Quad loop lookup and label imposition. 2 - optimise imposition for the 1 label case 3 - input gets TTL from header directly (no byte swap) Change-Id: I59204c9e5d134b0df75d7afa43e360f946d1ffe7 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-02-21dhcp: multiple additionsNeale Ranns1-0/+5
DHCP additions: 1) DHCPv4 will only relay a message back to the client, if the Option82 information is present. So make this the default. 2) It is no longer possible to select via the API to "insert circuit ID" - since this is now default 3) Remove the version 2 API since it's now the same as version 1. 4) Adding the VSS option is now conditional only on the presence of VSS config (not the 'insert' option in the set API) 5) DHCP proxy dump via API Change-Id: Ia7271ba8c1d4dbf34a02c401d268ccfbb1b74f17 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-02-02Fix SR multicast post mfib commitNeale Ranns1-9/+5
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.

2017-01-27IP Multicast FIB (mfib)Neale Ranns6-2/+931
- 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.

2017-01-05FIB memory leaks (VPP-578)Neale Ranns2-16/+19
1) vec_free the fe_srcs of a fib_entry_t when the fib_entry_t is itself reed 2) in the load-balance fixup if a drop path is required add this to a new vector of next-hops 'fixed_nhs'. This vector is managed by the load-balance function. The caller continues to manage its own set. The function is now const implying that the caller is safe to assume the next-hops do not change.
