There is no need to verify the checksum for packets that have the IP
checksum offload flag set. This uses the same logic as
ip4_ttl_and_checksum_check.

Checking for existence of source address on interface prevents creating
session before assigning address to said interface. Removing this check

In order to support the requirement of RSS and packet steering of new
protocols, such as GTPU PDU-type and QFI, for 5G UPF, a generic pattern
is introduced in vnet flow. The generic flow pattern is based on DDP
(Dynamic Device Personalization) function and Parser Library module in
DPDK. Using generic flow pattern, we do not need to create new packet
and field type and offset in API parser for every new protocols. We can
create flows for any protocol immediately as long as supported by DDP.
The generic flow can be used to support 5G related protocols in
different scenarios.
The input of this generic pattern are two binary strings for spec and
mask. Spec is the binary presentation of the target packet type, and
mask is used to mark the target fields.
In this patch DPDK plugins is enabled for POC. Next step we will enable
generic flow in native IAVF, which is the main target.
Here is an example. If we want to create a flow for GTPU QFI,
spec is:
00000000000100000000000208004500003C00000000001100000101010102020202000

01010102020202
mask is:
00000000000000000000000000000000000000000000000000000000000000000000000

A naming API POC is created via VAPI to help create the rule with
the target packet format similar to Scapy. It is based on a function
module called PacketForge. In this way, the user no need to create
binary string spec and mask by themselves.

As per IPSec RFC4301 [1], any non-matching packets should be dropped by
default. This is handled correctly in ipsec_output.c, however in
ipsec_input.c non-matching packets are allowed to pass as per a matched
BYPASS rule.
For full details, see:
https://lists.fd.io/g/vpp-dev/topic/ipsec_input_output_default/84943480
It appears the ipsec6_input_node only matches PROTECT policies. Until
this is extended to handle BYPASS + DISCARD, we may wish to not drop
by default here, since all IPv6 traffic not matching a PROTECT policy
will be dropped.

While setting an ACL, a user can specify the adjacency to follow after
the input ACL node. Thus, we may skip a lookup and enter directly a
local node (ex: ip4_local). To prevent the local source check from
failing, we need to specify the fib index. And, we have to do it just
before exiting the input ACL node because the l2_classify object
is overlapping with the fib_index in the vnet_buffer_opaque_t struct.
We could have added a padding to avoid this overlap but there is no
place for that in the structure.

Type: fix
- IPv6 fragmentation did not work if the packet spaneed multiple buffers, because the 'len' calculation to did max out at the size of a buffer
- IPv6 fragmentation did not work when the l2unfragmentable size was non-zero, it was not used in the correct places
- IPv6oMPLS fragmentation would fragment all IPv6, it should do so only for link local
- IPv6oMPLS should send back TooBig ICMP6 for non locally generated

For error conditions, such as TTL expired, dest unreach, etc, Rate limit the sending of ICMP error messages.
The rate limiting is done based on src,dst IP address of the received packet.
the rate limit has been chosen, somewhat arbitrarily, to be 1e-3. This is the same limit as the ARP throttling.

Ethernet frames on the wire are a minimum of 64 bytes, so use the length in the UDP header to determine if the ESP payload is one bytes of the special SPI, rather than the buffer's size (which will include the ethernet header's padding).
In the case of drop advance the packet back to the IP header so the ipx-drop node sees a sane packet.

When the adj subsystem is notified of a BFD session, it attempts to find the appropriate adjacency from the session's key.
This could lead to a mismatch between the adj used by BFD and that of FIB. The BFD session stores the adj it is using, so FIB uses that instead.
Since adj is now using the same adj as BFD, it does not need to maintain its own locks.
In BFD it is necessary to initialise the adj index used in INVALID and ensure it is not unlock before listeners are notified of the session delete.
