For some unknown reason sometimes calling exec() ends up on weak
exec() defined in src/vat/api_format.c which return -1 instead of using
one few lines above.
Another proof that use of weak symbols is bad idea.
Luckily this can be easily workarounded.

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.

With DPDK plugin, VPP does the DMA page map in IOMMU, only when
DPDK supported ethernet devices are present. As a result, Mellanox NIC
and QAT combo doesn't work. As part of this fix, DPDK supported
crypto device check is added to do the DMA page map.

This patch improves the per dpdk-input loop number of packets
received from the port. The change mimics how packets rx happened
before VPP 22.02/DPDK 21.11: instead of trying to rx huge number
of packets (256) in one go, rx more times with up to 32 packets
max each time.

Deadly combination is clib_{set,long}jmp + lazy linking + tail call compiler
optimization. On the first call to clib_setjmp, dynamic linker executes loader
code which then calls clib_setjmp, so stored stack position contains dynamic
loader data. Tail call optimization simply jumps back to the calling
code when clib_longjump is called and that results in wrong return
address used from the stack.

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: improvement
Currently, when an interface is brought down administratively, IPv4
routes that resolve through that interface remain in the FIB. However,
the kernel removes those routes but doesn't send any notifications about
that. Desynchronization between the kernel and VPP happens.
With this change, when a notification received from the kernel
indicating that an interface was brought down, in addition to bringing
the VPP interface down, walk the IPv4 FIB bound to that interface and
remove any entries that resolve through that interface and were added
with one of the linux-cp FIB sources.

- 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

Type: improvement
Currently, while reading notifications, ENOBUFS error is ignored and
reading continues. This was done to minimize the number of notifications
that are lost due to reopening the socket.
Now that synchronization is implemented to recover from socket errors,
ignoring ENOBUFS and reading as much notifications as possible is not
actual. Before synchronization, all currently enqueued notification are
discarded in any case.
With this change, stop reading notifications if any error occurs.

if original packet was to the link local, then the
fib index in the buffer is that of the LL table, we can't use that

In other case, the fib index we need has been written
