2017-10-10punt and drop features:Neale Ranns1-0/+6
- new IPv4 and IPv6 feature arcs on the punt and drop nodes - new features: - redirect punted traffic to an interface and nexthop - police punted traffic. Change-Id: I53be8bf4e06545add8a3619e462de5ffedd0a95c Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-09-20Add ip6-local feature arcPierre Pfister1-0/+1
ip4-local feature arc existed but not ip6-local one. This patch also adds node name to the 'show ip local' command and fixes a minor include issue in vnet/ip/ip4.h file. Change-Id: I9bb8a7159917d58f89afcce974680de20d946a70 Signed-off-by: Pierre Pfister <ppfister@cisco.com>
2017-09-11FIB table add/delete APINeale Ranns1-0/+13
part 2; - this adds the code to create an IP and MPLS table via the API. - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass. Change-Id: Id124d884ade6cb7da947225200e3bb193454c555 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-04-01MTRIE Optimisations 2Neale Ranns1-26/+3
1) 16-8-8 stride. Reduce trie depth walk traded with increased memory in the top PLY. 2) separate the vector of protocol-independent (PI) fib_table_t with the vector of protocol dependent (PD) FIBs. PD FIBs are large structures, we don't want to burn the memory for ech PD type 3) Go straight to the PD FIB in the data-path thus avoiding an indirection through, e.g., a PLY pool.

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-0/+24
- 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.
