According to RFC2131:
In the case of a client using DHCP for initial configuration (before
the client's TCP/IP software has been completely configured), DHCP
requires creative use of the client's TCP/IP software and liberal
interpretation of RFC 1122. The TCP/IP software SHOULD accept and
forward to the IP layer any IP packets delivered to the client's
hardware address before the IP address is configured; DHCP servers
and BOOTP relay agents may not be able to deliver DHCP messages to
clients that cannot accept hardware unicast datagrams before the
TCP/IP software is configured.
To work around some clients that cannot accept IP unicast datagrams
before the TCP/IP software is configured as discussed in the previous
paragraph, DHCP uses the 'flags' field [21]. The leftmost bit is
defined as the BROADCAST (B) flag. The semantics of this flag are
discussed in section 4.1 of this document. The remaining bits of the
flags field are reserved for future use. They MUST be set to zero by
clients and ignored by servers and relay agents. Figure 2 gives the
format of the 'flags' field.
this changes means VPP conforms to the:
"SHOULD accept and forward to the IP layer any IP packets delivered
to the client's hardware address before the IP address is configured"
with the caveat that VPP allows DHCP packets destined to the stanard client
DHCP port to be delivered. With this enhancement the control-plane is now
able to choose the setting of the broadcast flag.

- 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

L2 Emulation is a feautre that is applied to L2 ports to 'extract'
IP packets from the L2 path and inject them into the L3 path (i.e.
into the appropriate ip[4|6]_input node).
L3 routes in the table_id for that interface should then be configured
as DVR routes, therefore the forwarded packet has the L2 header
preserved and togehter the L3 routed system behaves like an L2 bridge.

Add API function which enables forwarding of packets not matching
existing translation or static mapping instead of dropping them.
When forwarding is enabled matching packets will be translated
while non-matching packets will be forwarded without translation.

as decsribed in section 2.2
ihttps://tools.ietf.org/html/draft-ietf-bier-mpls-encapsulation-10
with BIFT encoding from:
https://tools.ietf.org/html/draft-wijnandsxu-bier-non-mpls-bift-encoding-00
changes:
1 - introduce the new BIFT lookup table. BIER tables that have an associated
MPLS label are added to the MPLS-FIB. Those that don't are added to the
BIER table
2 - BIER routes that have no associated output MPLS label will add a BIFT label.
3 - The BIER FMask has a path-list as a member to resolve via any possible path.

This allows to use the classifier to steer source routing packets instead
of using the "sr steer" command.
This way we can steer on anything instead of only the dst ip address.
test:
* add add_node_next function to the VppPapiProvider class.
* add simple test scenario using the classifier to steer packets with
dest ip addr == a7::/8 to the source routing insert node.
* use new interface indexes (3,4) instead of (0,1) to prevent a cleanup
conflict with the other tests which attach a specific fib to the
interface.
The test creates interfaces sepsrated from the other tests to prevent a
conflict in the cleaning of the ip6 fib index 1 which causes vpp not to
be able to find a default route on this table.

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.

Notes on this first implementation:
* First version of the implementation does NOT support GENEVE OPTIONS
HEADER: it isn't well understood what the purpose of the OPTIONS will be and/or
what content would be placed in the variable option data;
Once the IETF work will evolve and further information will be available
it could be possible to modify the frame rewrite to contemplate the
actual GENEVE OPTIONS.

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.

The replacement of [] with pool_elt_at_index and subsequent fixing it
was incorrect - it was equivalent to &[], since it returns a pointer to
the element. I've added VPP-993 previously to create a testcase,
so this commit partially fulfills that one as well.

Supports 64K PPPoE sessions
This plugin adds three graph nodes:
1) pppoe-input for PPPoE decapsulation
2) pppoe-encap for PPPoE encapsulation
3) pppoe-tap-dispatch for control plane process
Below is the configuration to make PPPoE CP and DP work:
vim /etc/vpp/startup.conf
tuntap {
enable
ethernet
name newtap
}
create pppoe tap tap-if-index 1
//Configure it after a subscriber's PPPoE discovery and PPP link establishment succeeds:
create pppoe session client-ip 100.1.2.1 session-id 1 client-mac 00:11:01:00:00:01
show pppoe fib
