Remove broken special case from l2_input.c:set_int_l2_mode(), which
turns out to confuse the graph dispatch engine.
The loopback TX function needs to push packets to either
ethernet-input or to l2-input, based on bridge / BVI
configuration. Rather than overloading a single graph arc - and making
vain attempts to reconfigure it - create both arcs and use the correct
one.
Rewrote the loopback tx function as an idosyncratic multi-arch
quad/single loop fn.

For L2 ARP termination, use both brodcast ARP request and reply
packets to provide MAC/IP binding events.
For IP4/IP6 neighbor adress resolution, send resolution events
if there is an address resolution attemp with a static neighbor
entry where both IP and MAC matches. This allow probe of an IP
neighbor with a static entry to confirm it is responding with
a reply matching that of the static entry.

A pipe resembles a unix pipe. Each end of the pipe is a full
VPP interface.
pipes can be used for e.g. packet recirculation, inter-BD, etc.

This patch separates setting of hardware interfaec and software
interface MTU. Software MTU is L2 payload MTU (i.e. not including L2
header). Per-protocol MTU for IPv4, IPv6 and MPLS can also be set.
Currently only IP4, IP6 are enabled in adjacency / rewrite code.
Documentation in src/vnet/MTU.md

- Modify the API send_ip6_na and send_ip4_garp to take sw_if_index instead
of vnet_hw_interface_t and add call to build_ethernet_rewrite to support
subinterface/vlan
- Add code to bonding driver to send an event to bond_process when the first
interface becomes active or when the active interface is down
- Create a bond_process to walk the interface and the corresponding
subinterfaces to send garp/ip6_na when an event is received.
- Minor cleanup in bonding/node.c
Note: dpdk bonding driver does not send garp/ip6_na for subinterfaces. There is
no attempt to fix it here. But the infra is now done and should be easy to
add the support.

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.

Use device-input and interface-output feautre arcs to collect unicast, multicast
and broadcast states for RX and TX resp. Since these feature arcs are present only
for 'physical' interfaces (i.e. not su-interfaces) counter collection is supported

The interpose source allows the source/provider to insert/interpose
a DPO in the forwarding chain of the FIB entry ahead of the forwarding
provided by the next best source. For example if the API source (i.e
the 'control plane') has provided an adjacency for forwarding, then
an interpose source (e.g. a monitoring service) couold interpose a
replicatte DPO to copy the traffic to another location AND forward
using the API's adjacency.
To use the interose feature an existing source (i.e FIB_SOURCE_PLUGIN_HI)
cn specifiy as a flag FIB_ENTRY_FLAG_INTERPOSE and provide a DPO to
interpose. One might also consider using interpose in conjunction with
FIB_ENTRY_FLAG_COVER_INHERIT to ensure the interpose object affects
all prefixes in the sub-tree.

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

- Global variables declared in header files without
the use of the 'extern' keword will result in multiple
instances of the variable to be created by the compiler
-- one for each different source file in which the
the header file is included. This results in wasted
memory allocated in the BSS segments as well as
potentially introducing bugs in the application.

For bonded interface in Active/Backup mode (mode 1), we need to
send a GARP/NA packet, if IP address is present, on slave link
state change to up or down to help with route convergence. The
callback from DPDK happens in a separate thread so we need to make
sure RPC call is used to signal the send_garp_na process in the
main thread. Also need to fix DPDK polling so the slave links are
not polled.
