With this commit, forward the translated packet directly to the
specified next-hop if pre-resolve param is enabled in MAP-T.

Prevent malicious packets with spoofed embedded IPv4 addresses
by limiting the IPv6 ingress packets to known MAP-T domains.
Drop spoofed packets.
Add several tests that ensure spoofing isn't allowed.

Remove NAT's implementation of shallow virtual reassembly with
corresponding CLIs, APIs & tests. Replace with standalone shallow
virtual reassembly provided by ipX-sv-reass* nodes.

Type: fix
Ticket: VPP-1804
Fix a regression introduced by 640edcd90.
The port set ID on received IPv6 packets for MAP-T was being
checked against the destination port. It should be checked
against the source port.
Added a new unit test to verify that a v6 packet with a good
source port is translated and forwarded and a v6 packet with
a bad source port is dropped. The important part of the test
which will prevent similar future regressions is that the
source port and destination port are not equal. The existing
unit test used the same source and destination port which is
why it did not fail when the regression was introduced.

This provides a functional interface to IP fragmentation.
Allowing external features to fragment. Supports
arbitrary encap size, for e.g. MPLS or inner fragmentation
of tunnels.
This also removed dual loop in MAP that was fundamentally broken.

This change is part of an effort to unify reassembly code. By removing
shallow virtual reassembly functionality in MAP and using the common
vnet provided shallow virtual reassembly, code size and complexity
is reduced.

This reverts commit 0ae15ed43aaa600a75ca4c154bc62478820c00b4.

- Error where ICMPv6 error code doesn't reset VLIB_TX = -1
Leading to crash for ICMP generated on tunnelled packets
- Missed setting VNET_BUFFER_F_LOCALLY_ORIGINATED, so
IP in IPv6 packets never got fragmented.
- Add support for fragmentation of buffer chains.
- Remove support for inner fragmentation in frag code itself.

Only remaining traces of MAP in the src/vnet is now in buffer.h.
Awaiting a new buffer opaque API (hint, hint).
