Scan IPv4 and IPv6 neigbor pool entries once a minute to keep them
up to date. The neighbor of an entry is probed if its time-stamp
is older than 1 minute. If the neighbor respond, its time-stamp
will be updated. If there is no response from a neighbor, its
entry will be deleted when the time-stamp of the entry become more
than 4 minutes old. Static neighbor entries are not probed nor
deleted.
Implemented CLI and API to enable and disable priodic scan of IPv4,
IPv6 or both types of IP neighbors. CLI is "ip scan-neighbor" and
API is "ip_scan_neighbor_enable_disable". Other IP neighbor scan
parameters can also be changed from their defaults via the CLI/API.

Add API support similar to VPP CLI "ip probe-neighbor" except API
call is asynch and will not wait, as the CLI does, for address
resolution of probed neighbor. The API client can use the APIs
want_ip4_arp_events or want_ip6_nd_events to get notified of the
desired address resolution event.

This change makes ip reassembly an interface feature, while adding
concurrency support. Due to this, punt is no longer needed to test
reassembly.

- support both pipe and uniform modes for all MPLS LSP
- all API programming for output-labels requires that the mode (and associated data) is specificed
- API changes in MPLS, BIER and IP are involved
- new DPO [sub] types for MPLS labels to handle the two modes.

This is a version of the VPP API generator in Python PLY. It supports
the existing language, and has a plugin architecture for generators.
Currently C and JSON are supported.
Changes:
- vl_api_version to option version = "major.minor.patch"
- enum support
- Added error checking and reporting
- import support (removed the C pre-processor)
- services (tying request/reply together)
Version:
option version = "1.0.0";
Enum:
enum colours {
RED,
BLUE = 50,
};
define foo {
vl_api_colours_t colours;
};
Services:
service {
rpc foo returns foo_reply;
rpc foo_dump returns stream foo_details;
rpc want_stats returns want_stats_reply
events ip4_counters, ip6_counters;
};
Future planned features:
- unions
- bool, text
- array support (including length)
- proto3 output plugin
- Refactor C/C++ generator as a plugin
- Refactor Java generator as a plugin

- rename l2_bridged to is_dvr. Including on the ip.api
this was new in the 18.01 release so no compatability issues.
- steal the free space in vnet_buffer_opaque_t for use with flags.
- run the ipX-output feature arc from the DVR DPO

When a DUMP with sw_if_index == ~0 is used to get all Neighbor
entries for all interfaces, it is unclear in the details to
which interface the neighbor belongs.
Clear that up by returning the associated sw_if_index as well.

A UDP-encap object that particiapates in the FIB graph and contributes
DPO to teh output chain. It thereofre resembles a tunnel but without the
interface. FIB paths (and henace routes) can then be created to egress
through the UDP-encap. Said routes can have MPLS labels, hence this also
allows MPLSoUPD.
Encap is uni-directional. For decap, one still registers with the UDP port
dispatcher.

Vat supports setting value for the parameter, but
'not_last' is ignored by ip_add_del_route handler,
so can be removed.
This patch
- updates ip.api,
- removes vat handlers
- updates vpp_papi_provider.py
(also mpls_route_add_del with unused not_last)

This reverts commit f9342023c19887da656133e2688a90d70383b0c5.
Reverting to unblock master. No idea why jjb +1ed this patch! On closer inspection it looks like it -1ed it and subsequently changed opinion. CSIT tests should be fixed before re-merging.

A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.

Paths are given a preference, lowest value is 'best'. Only paths that are up are up contribute to fprwarding - that's unchanged. What's new is that of the path's that re up only those that have the best preference contribute. A poor man's primary and backup. It's not true primary/backup function because the FIB must converge before the lower preference paths are used.

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.

bridging. That is hosts in one sub-net reachable via differenet interfaces.
Introducate a new API command:
ip6 nd proxy <host-address> <interface>
this indicates 2 things;
1) that host <host-address> is reachable out of interface <interface>. VPP will thus install that route.
2) NS requests sent to <host-address> will be responeded to (i.e. proxied).

When handling the IP_DETAILS and IP_ADDRESS_DETAILS replies,
it is almost certainly going to require having both the is_ipv6
and sw_if_index context to handle them properly. Placing these
values in an essentially global location as the current VAT does
isn't thread-safe. Fruthermore, rather than forcing every
API user to hoop-jump to establish these context values, simply
provide them in their DETAILS reply messages.

- 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.
